Remote Solar Pump & Tank Installation

Case Study

Customer: QLD Cattle Grazier

Location: Kalapa, QLD

Specifications & Features:

A Rockhampton regional cattle grazier (located in Kalapa, QLD) employed Dowdens Pumping & Water Treatment [Rockhampton] to design, install and commission an economical yet efficient pumping solution to supply water for 50 head of cattle in a remote paddock.

The paddock in question has no access to mains electricity or town water so Dowdens needed to find a way to efficiently pump the water drawn from a 12m deep well into a newly installed poly water tank, eliminating the need to use the old onsite windmill. A solar powered pump and controller unit needed to be used.

Nu-Tank RockhamptonDowdens contacted local business Nu-Tank to float the idea of establishing an ongoing Rockhampton-based partnership to manufacture and deliver Dowdens dedicated solar pumping solutions in unison with their locally manufactured reliable one piece water tanks to farmers, graziers and local industry alike.

Working in partnership with Stephen Trail [Manager] from Nu-Tank Rockhampton the Dowdens Pumping & Water Treatment Rockhampton branch were able to co-design, test and develop specialised poly lugs that can be welded to the top of each tank. This has allowed Dowdens wide range of solar panels to be fitted safely and securely to the top of Nu-Tank's dedicated solar pumping water tanks.

"Partnering with Dowdens Pumping & Water Treatment [Rockhampton] has allowed both companies to better service the farming and grazier community with specialised solar pump / tank systems. Combining Nu-Tank's quality storage solutions with Dowdens years of solar pumping expertise has seen the development of our unique and reliable solar pump / water tank products. We look forward to working closely with Dowdens in the years to come supplying affordable solar pump and tank solutions to farmers, graziers and local Rockhampton businesses."

Dowdens Pumping & Water Treatment - Nu-Tank Remote Solar Tank and Pumping Installation [Kalapa, QLD]

Details:

The solar pumping system was designed to keep overall costs down whilst still delivering a regular supply of water to the cattle with negligible ongoing service or labour required.

A 3HRSS Waterboy submersible solar pump was installed in the onsite well at a depth of approximately 12m. The solar pump then transfers artesian bore water via metric poly pipe to the nearby specially adapted Nu-Tank poly water tank. The tank then gravity feeds a series of troughs throughout the paddock sufficiently watering the 50 head of cattle.

The Nu-Tank PWT3300 15,000L poly water tank was fitted with a PC500 Waterboy pump controller allowing the pumps flow rate and pressure to be easily managed via the easy-to-use electronic interface. The daily flow into the water tank is now approximately 6,000L - which is more than enough to properly water the 50 head of cattle in the paddock.

The top of Nu-Tank poly water tanks are rated to hold a much greater weight than the installed solar panels - meaning the environmental footprint of the entire solar setup was minimised and the grazier saved money on the total project costs.

Cannonvale Medical Centre Water Treatment System post Cyclone Debbie

Wednesday, 19 April 2017

Severe Tropical Cyclone Debbie made landfall near Airlie Beach on the Nth QLD coast 28th March 2017. It was a slow-moving category 4 system that generated wind gusts exceeding 160 km/hr, heavy rainfall and storm surges along the Nth QLD coastline. 27 hours later, after having tracked inland over Airlie Beach, Proserpine, Cannonvale and Collinsville it was downgraded to a Tropical Low. Dowdens Pumping & Water Treatment's Proserpine Branch is again open for business.

Cannonvale was amongst the hardest hit regions during Cyclone Debbie, so it was no surprise to Dowdens Pumping & Water Treatment's Proserpine Branch to hear Queensland Health had been advised they couldn't be guaranteed potable water supply to their Whitsunday Community Health Centre located in Cannonvale immediately after Cyclone Debbie.

Luckily Dowdens Pumping & Water Treatment's Head Office in Mackay had a portable Ultrafiltration Treatment System available, capable of supplying up to 70,000 litres of potable water per day. Queensland Health and the Whitsunday Community Health Centre in Cannonvale instructed Dowdens Pumping to supply/install the unit immediately on a temporary 'Hire' agreement in-case all mains water supply was lost.

There were two water sources available at the time - the mains water supply or bore water from the Proserpine Hospital. Queensland Health instructed Dowdens to connect the UF Treatment System to the bore water supply, in an effort to remain as self-sufficient as possible post-Cyclone Debbie.

PURION - Water Treatment Products by the Dowdens Group

Dowdens Pumping have previously completed numerous bore water filtration systems treating bore water with our own brand of PURION Iron Removal Filters, so this emergency UF Treatment System was quick and easy to install. PURION Iron Removal Filters pre-treat the bore water before running it through the Ultrafiltration System which then doses the filtrate with liquid chlorine to further disinfect.

Once treated Dowdens Pumping manually transported numerous loads of the potable water from the Proserpine Hospital (where the UF System was installed) directly to the Whitsunday Community Health Centre in Cannonvale, where it was stored in a potable water grade storage tank. The treated water was then used to supply the medical centre. The entire supply/installation and commissioning was successfully completed on Saturday 1st of April - only 4 days after Cyclone Debbie had hit.

If you are ever in need of potable water during a storm or emergency contact Dowdens Pumping & Water Treatment. Dowdens only require access to a reasonable source of water (bore, dam, creek) and power (generator or mains power) and we can guarantee same day potable water supply, in any situation!

Location: Port Douglas, QLD

Specifications & Features:

Sheraton Mirage Port Douglas Resort

Dowdens Pumping & Water Treatment's Proserpine branch provide a range of products and services to island resorts throughout the Whitsundays and Northern Queensland; supplying and servicing everything from pool pumps to major sewage treatment / pumping stations and irrigation systems. We pride ourselves on being able to provide a large range of products across all facets of resort infrastructure.

Dowdens Pumping & Water Treatment's Proserpine branch regularly service customers across local off shore resorts, as well as working extensively with mainland tourist attractions and resorts for both sales and servicing. With extensive knowledge and experience in this area we are confident that our team of experts can provide solutions to clients problems. Dowdens Pumping carries a large range of spare parts and our service team are proud to provide comprehensive and professional after-sales service.

Recently Dowdens Proserpine were engaged by Fullshare Holdings (owner / operators of the Sheraton Grand Mirage Resort Port Douglas) to upgrade 5 existing onsite pump stations that had reached the end of their service life. At the projects inception Dowdens Proserpine conducted a thorough audit of the onsite pumping systems - the subsequent detailed report submitted to Fullshare Holdings resulted in Dowdens being awarded the contract to replace the ageing sewage pump stations. Dowdens Proserpine then set about designing a more efficient and reliable sewerage pump system that was to include smaller and more energy efficient Grundfos pumps, resulting in a reduction in the required maintenance and considerably lower overall energy use onsite. Dowdens Pumping & Water Treatment are Authorised Grundfos Dealers throughout the Whitsundays / Mackay / Rockhampton regions.

"Fullshare (owners of Sheraton Grand Mirage Resort & Mirage Country Club) recently engaged Dowdens Pumping & Water Treatment's Proserpine branch to carry out an on-site audit & submit a report on the condition & performance of our 30 year old sewage pump stations. This audit & subsequent detailed report was thorough & included recommended actions, therefore allowing Fullshare to be fully informed on the condition & improvements required to improve the condition & performance of these important components of our asset. Following a Tender process, we engaged Dowdens Pumping & Water Treatment to carry out the recommended upgrade works to the sewage pump stations.

The challenges of the project were met well by Dowdens Pumping & Water Treatment under the management & extensive office / site based efforts of Kevin Krog (Dowdens Proserpine branch) & his industrial workshop team. Such challenges faced were a fully operational Resort & Country Club, difficult access to some stations, 30 year old supporting infrastructure & services including power supplies as well as contending with it being the wettest & most humid time of the tropical year. Kevin was also excellent at assisting us to liase with the Douglas Shire Council for these works. We will continue to utilise Dowdens Pumping & Water Treatment's expertise & personnel at this property when the need arises & would thoroughly recommend them for these types of works."

Fullshare Holdings - Sheraton Mirage Port Douglas Resort

Once the design was accepted Dowdens began works that would see 10 new Grundfos sewerage pumps being installed in 5 existing pump stations. The projects scope included supplying and fitting all rails, brackets, lifting chains, concrete pump station lids and non-return valves. Together with the design and installation of Grundfos electronic control panels (Grundfos CU362 Waste Water Controllers) & remote monitoring systems (Grundfos Remote Management [GRM]) which allows for SMS & Email to be sent to relevant site operators alerting them to any faults. The GRM system also allows for system alarms to be reset and pump duties to be modified remotely via any smart-phone or PC. Full product and system descriptions can be viewed below.

The aim of this project was to provide a modern and efficient sewerage pumping system that was energy efficient, reliable, had improved remote monitoring capability and increased level of safety for Dowdens Servicing and onsite technicians. The Dowdens Infield Service Crew began by removing the existing 30-year-old pumps, rails, brackets, lifting chains, heavy concrete lids and control panels. These were replaced with more efficient and reliable Grundfos pumping and monitoring equipment. During installation and commissioning Dowdens had to schedule works to meet the resorts strict operation requirements, ensuring the project proceeded with little to no impact on the resort guests.

The existing concrete lids were damaged and unsafe and needed to be replaced. Dowdens provided 'light lift' aluminium lids with integrated safety grates (pictured below) to minimise the risk of falling into the wet well whilst servicing the pumps. 3 out of the 5 existing control panels were deemed unsafe by Dowdens Electricians and required replacement with new stainless steel panels incorporating the Grundfos CU362 Pump Controllers and Grundfos Variable Frequency Drives on the 2 main pump stations. Dowdens also provided Sheraton Grand Mirage Resort Port Douglas with scheduled servicing of the Grundfos SEV & SE1 pumps; Grundfos CU362 Waste Water Controllers; Grundfos Remote Management [GRM] Systems; Dowdens custom built aluminium lids with safety grates; Stainless steel pump rails; 800kg rated lifting chains & the Backflow protection on wash down taps. The entire project was delivered on time and within budget.

Dowdens Pumping & Water Treatment design philosophy for this project was: Cost Effectiveness - Current Best Practice - Ease of Installation - Simple & Effective Plant Operation - Pump Station Reliability - Advanced Remote Management Capabilities - Reduced Ongoing Maintenance.

Game changing GRUNDFOS SCALA2 PUMPS now at Dowdens

Tuesday, 14 March 2017

Dowdens Pumping & Water Treatment are your local pump experts and are Authorised Grundfos MASTER DEALERS. Dowdens are Mackay's ONLY Authorised Grundfos MASTER DEALERS & Dowdens Rockhampton branch is also an Authorised Grundfos MASTER DEALERS. Grundfos pumps are market leaders, committed to providing new and innovative products that take comfort and simplicity to the next level, for these reasons we sell and recommend the new SCALA2 domestic pump.

Grundfos has long been regarded for their high quality and reliable pumps. The Grundfos SCALA2 takes design innovation, comfort and simplicity to the next level and is set to be a game changer in domestic boosting. The NEW Grundfos SCALA2 is a robust, fully integrated, self-priming pump suitable for use from both above and below ground water sources. The compact system features a pump, motor, tank, sensor, drive and non-return valve in one compact unit that is quick and easy to install.

The SCALA2 is an energy efficient pump featuring an integrated speed controller that ensures constant water pressure regardless of variations in demand or inlet pressure. For those living in areas of poor power supply or those that are sometime affected by power outages, the SCALA2 can also be run on a generator, due to its ability to be able to handle varying voltages.

The variable speed controller also matches the power consumption with the required water output, which also helps to conserve energy and reduce your energy bills. To protect the pump and help ensure a long life, the SCALA2 includes a range of protective features. Dry run protection automatically stops operation when the water source runs out, to help prevent damage, and the anti-cycling feature detects any unnatural cycling and alerts the user via the protection indicator on the control panel.

Another unique benefit of the SCALA2 is its quiet operation, thanks to the permanent magnet motor and water cooling technology. The high efficiency motor is significantly quieter than traditional speed-controlled motors and the SCALA2 is cooled by the water it pumps, eliminating the need for a noisy fan. This makes the SCALA2 one of the quietest domestic boosting pumps currently available on the market.

For ease of selection, the SCALA2 suits most domestic pressure boosting applications and is capable of supplying water for small single level homes up to larger multi-storey homes.

Coppabella Township Sewage Treatment Plant Upgrade

Case Study

Customer: Aurizon Holdings Limited

Location: Coppabella, QLD

Specifications & Features:

Aurizon Holdings Limited

Following on from the successful construction and commissioning of the Coppabella Water Treatment Plant Aurizon Holdings Limited engaged Dowdens Pumping & Water Treatment [Mackay & Brisbane Branches] to deliver a much needed Sewage Treatment Plant (STP) Upgrade at their Coppabella Township, located on the Goonyella Rail Corridor (the world's largest metallurgical coal rail system) - 159 kilometres South West of Mackay, QLD. The Coppabella STP Upgrade project entailed the addition of an Ultra-Filtration (UF) 'Polishing' Plant onto the existing STP. Dowdens new UF 'Polishing' Plant can produce up to 180 kL/day of treated Class A effluent.

The township of Coppabella was primarily designed and built to service the junction of two railway lines (one from Goonyella Coal Mine and one from Saraji Coal Mine) and to provide accommodation to the regions coal mine workers in work depots. The town is wholly owned and operated by Aurizon Holdings Limited and contains: stations, residences, single-quarters, work depots, hotel, a shop, swimming pool, football oval, caravan park, school, ambulance, fire brigade, the recently completed Dowdens whole-of-town Water Treatment Plant and of course the upgraded Sewage Treatment Plant which is now capable of producing 180kL of treated Class A effluent per day for above ground irrigation applications. The local Coppabella Golf Course is one area where this treated effluent is used for irrigation.

After successfully completing various projects for Aurizon Holdings Limited, Dowdens won the tender to provide the process design together with equipment supply, civil construction, installation, commissioning and training for the STP plant operators. The construction phase of the project began with extensive civil works being undertaken to raise the ground level for the new STP components. The pre-existing STP has historically been subject to flooding during heavy rainfall events due to the sites proximity to the local creek. Upon surveying the sites substrate a water table was discovered 1m below ground level.

Working with local Civil Engineers Cardno a substantial foundation was designed / laid to ensure the new buildings, plant components and 4,000 tonne water tank would be stable and remain above the flood plain even during heavy rainfall. Once foundations were laid Dowdens began construction of the 400,000L lined stainless steel water tank, new building to properly house the STP process equipment, an operators office, laboratory facilities and a back-up generator used to power the entire STP in the event of power loss.

Dowdens Pumping & Water Treatment Coppabella Township Sewage Treatment Plant Upgrade [Coppabella, QLD]

Details:

After extensive effluent testing and thorough examination of the existing STP process a UF 'Polishing' Plant was designed by Dowdens inhouse Water Treatment Engineering Dept. capable of processing up to 180kL of partially treated sewage effluent per day. The partially treated sewage effluent was rated as Class C and needed to be treated to an acceptable level (Class A) to then be used for above ground irrigation. This treatment process consists of three stages of filtration and sterilisation, including UF. This three-stage process runs as follows:

  • Primary treated effluent from the existing STP (Class C quality) is transferred to a 45,000L Glass Media Filtration (GMF) feed tank via duty / stand-by submersible pumps on demand.
  • In Stage 1 the clarified effluent from the existing STP process is first dosed with sodium hypochlorite as primary disinfection, to reduce biofouling of the Glass Media. It is then passed through the duty/stand-by Glass Media Filters which reduce particulates, suspended solids and turbidity from the GMF filtrate stream. This ensures no large particles damage the UF membranes in Stage 2.
  • In Stage 2 the GMF filtrate is then passed through UF treatment process which incorporates 5% 'cross-flow' to maximise the filtration run-time between back flushes (triggered by high trans-membrane pressure). The systems consists of 8 individual outside-in PVDF membranes which reduce turbidity to less than 1 NTU (Nephelometric Turbidity Units) whilst removing any particles greater than 0.0002mm from the permeate stream. The UF feed is again dosed with sodium hypochlorite to assist with cleaning the UF membranes from biological and organic fouling between the backwash and Chemical Enhanced Back Flush (CEBF) cycles.
  • In Stage 3 the UF filtrate is passed through duty/stand-by Activated Carbon Filters (ACF) on demand to reduce colour and odour (by removing aromatic compounds) as a final 'polish' before being fed to the treated effluent tank. The ACF filtrate is then dosed with sodium hypochlorite as a final disinfection of the treated effluent prior to it entering the treated effluent storage tank for dispersal via above ground irrigation systems. Dowdens provided a centralised, custom designed / fabricated, packaged chemical dosing system for this UF 'Polishing' Plant which included a 1000L Chemical Storage tank, a splash-proof racking area housing 5 individual Chemical Dosing pumps - complete with an internal bund and double containment dosing line connections.

When the treated effluent arrives in the 400kL stainless steel tank a recirculation system pumps it through a chlorine analyser and back to the treated effluent tank. The chlorine analyser then controls the residual free chlorine level in the treated water and will start / stop a chemical dosing pump as required to maintain the pre-set residual free chlorine level.

Each of the GMF, UF and ACF processes are periodically backwashed and cleaned, with residual waste being fed to a nearby buffer dam where chlorine is allowed to dissipate. Based on the level in the buffer dam and the level in the treated effluent tank, the water may then be returned to the pump station at the front of the STP for reprocessing.

With a history of successful installations over the past 20 years throughout the Queensland Mining Sector Dowdens Pumping & Water Treatment have the ability to expertly design / manufacture / install and commission specialised pumping and water treatment solutions that are built primarily in-house & onsite to client's specific unique requirements. The Coppabella STP Upgrade project is yet another example of Dowdens unparallelled capability to deliver specialised long-term engineered fluid handling solutions from project inception through to final commissioning / handover.

Cattle Feed Paddock Irrigation System

Case Study

Customer: Arabon Seafoods

Location: Bowen, QLD

Specifications & Features:

Arabon Seafoods employed Dowdens Pumping & Water Treatment [Mackay] to deliver a broad acre irrigation system watering their cattle feed pasture located in Bowen, QLD. Arabon Seafoods are a proud Queensland small business specializing in the sale and export of locally sourced live, chilled and frozen seafood.

Dowdens designed an efficient energy and water use irrigation system for Arabon Seafoods that utilises a Valley Two-Wheel-Linear Irrigator - the ideal irrigator for smallholder growers with limited access to electricity - together with a Nelson S3000 Spinner Sprinkler Package, Nelson 110VAC Shut-Off Valve, Valley Autopilot GPS Ready Control Panel and a Yanmar 10kVa 3-Phase Diesel Generator Set.

The Valley Two-Wheel-Linear Irrigator is a fairly standard machine in it's configuration but it's application to Arabon's cattle feed pasture is a departure from local practice. Most irrigation in this region is normally provided by low pressure boom type irrigators which are far less efficient in regards to energy and water consumption when compared to the Valley machine.

The system is required to pump water directly from onsite bores to the Valley Two-Wheel-Linear Irrigator watering 3.5 ha of cattle feed pasture. The irrigator's purpose is to provide water to a 'baleable' hay crop which is periodically onsold to local graziers as stock feed. The installation of a Valley linear irrigator has greatly reduced the number of irrigation runs that Arabon Seafoods has previously undertaken with their smaller boom type irrigator to water the same area of crop. Valley Two-Wheel-Linears deliver the ability to easily tow or swing the machine around to cover more acres.

Valley's 'easy to operate' Valley Autopilot GPS Ready Control Panel has enabled other Arabon Seafoods personnel to operate the irrigator which had always proved difficult in the past using a more dated irrigator. The GPS Ready Valley Autopilot Control Panel allows linears to automatically perform functions similar to a center pivot. The AutoPilot Linear measures the lateral position and direction of travel of the linear, allowing functions to be easily programmed to run automatically.

Dowdens Pumping & Water Treatment [Mackay] are the sole Valley Irrigation Master Dealers for the Mackay / Whitsunday region enabling the best possible pricing and unmatched product support for all of our customers.

Dowdens Pumping & Water Treatment Broad Acre Cattle Feedlot Irrigation System [Bowen, QLD]

Details:

Arabon Seafoods contacted Dowdens Mackay in mid-2015 and requested a site visit and quote. Within a week the Dowdens Ag Sales Team were onsite taking measurements and discussing options with the business owners. A system was designed to suit the area and application, and the quote was delivered. Arabon Seafoods was happy with the design and pricing and instructed Dowdens they would budget for this system in 2016.

Fast forward to mid-2016, working closely with the business owners Dowdens had successfully refined the quote and sourced all materials to be supplied. The purchase order arrived with Dowdens in late May 2016 - the irrigator was delivered to site on Friday 24th of June. The installation commenced Monday 27th of June and the machine was fully operational and commissioning was completed by Wednesday 29th of June.

Dowdens Pumping & Water Treatment's design philosophy for this project was: Cost Effectiveness - Current Best Practice - Ease of Installation - Simple & Effective System Operation - System Reliability & Delivering Reduced Ongoing Maintenance Requirements.

Emergency Irrigation Pivot Repairs

Case Study

Customer: Racecourse Projects

Location: Marwood, QLD

Specifications & Features:

Racecourse Projects - Dowdens Emergency Infield RepairsRacecourse Projects recently engaged Dowdens Pumping & Water Treatment's Mackay 'Infield Service Crew' to undertake emergency repairs to a damaged Valley Irrigation Centre Pivot Irrigator at their Sugar Cane Farm located in Marwood, QLD.

This project began, like most emergency repair jobs do with an unexpected call from our customer. Racecourse Projects rang the Dowdens Pumping Agricultural Sales Team to inform them a Cane Haul-Out Truck had struck the first span of their Valley Centre Pivot. The pivot was now hanging precariously and needed to be repaired immediately. Daryn Gray (Dowdens - Industrial Workshop [Engineering Support]) and Brett Hayes (Dowdens - Agricultural Sales) promptly attended the Marwood site and assessed the pivot. Dowdens advised the pivot needed to be supported or it may have collapsed further. Straightaway the Dowdens 'Infield Service Crew' were onsite to elevate and secure the damaged span.

After speaking directly with the manufacturer of the damaged Valley Centre Pivot (Valmont Industries - Australia) Dowdens confirmed with Racecourse Projects there were no suitable spans for that machine currently available anywhere in Australia. This meant repairs needed to be undertaken promptly before the machine potentially collapsed completely - making any further repair work impossible. Dowdens then promptly engaged a local subcontractor to work alongside the Dowdens 'Infield Service Crew' repairing the machine in situ (whilst still suspended in the air). As the repairs had to be effected whilst the machine was still standing, this required coordination between 2 cranes and a telehandler forklift, along with a man box (attached to the all terrain telehandler) for 2 men to carry out the repairs. All the repairs and commissioning of the irrigator were successfully completed within 2 days of the accident!

Dowdens Pumping & Water Treatment [Mackay] are the sole authorised Valley Irrigation Master Dealers for the Mackay / Whitsunday region enabling access to the best possible pricing and product support, an unmatched range of spare parts & fast-turnaround repairs for all of our customers irrigators.

Longwall Boost Pump Station

Case Study

Customer: Anglo American - Australia

Location: Moranbah North Coal Mine - Moranbah, QLD

Specifications & Features:

Anglo American Moranbah North Coal Mine

Dowdens Pumping & Water Treatment's Mackay branch was engaged by Anglo American - Moranbah North Coal Mine to design, engineer and build a boost pump station to supply raw water to the longwall area. Dowdens Pumping & Water Treatment designed and built the longwall boost pump station utilising dual variable speed pumps to enable the station to cater for varying duties as the underground workings progress further away from the station.

Anglo American's Moranbah North coal mine began operation in 1998 as an underground longwall mine and currently supplies 4.5m tonne annually of high fluidity premium hard coking coal mainly for export to iron and steel manufacturers in Japan, Korea and Taiwan.

All design, fabrication, installation & commissioning of the longwall boost pump station was undertaken by Dowdens Mackay's in-house Engineering, Fabrication & Workshop Departments and all electrical componentry of the longwall boost pump station was supplied, installed and commissioned by Major Electrical. With a history of successful installations over the past 20 years throughout the Queensland Mining Sector Dowdens Pumping & Water Treatment have the ability to expertly design / manufacture / install and commission specialised pumping and water treatment solutions that are built primarily in-house & onsite to our client's specific unique requirements.

Dowdens dedicated departments of industry trained engineers, draftsmen, project managers, sales staff and tradespeople including fitters, mechanics, polywelders, machinists, plumbers, electricians and boiler makers enable us to offer an unmatched range of world-class engineering solutions for any type of water management project. We truly are Queensland's premier one-stop-shop for pumping and water treatment systems!

"The longwall booster pump station was taken underground into immediate service after only a couple of days. There is normally a one or two month delay with above ground commissioning for all new units. Since the pump powered up after the first run it has not stopped running and is sitting at only 10% duty. The longwall has cut 128,000 tonnes so far which is exceptional. Any future boost pump orders from Dowdens Pumping & Water Treatment will not require any changes to the design or manufacture saving us both time & money."

Moranbah North Coal Mine - Longwall Boost Pump Station

Details:

The pump station boosts water pressure to the longwall currently some 6,000m away. Comprehensive 'pre-challenge' testing was completed prior to the station being transported to site, with all parameters being set during this time. Dowdens internal teams of specialised engineers, CAD draftsmen and tradespeople were able to design and build the station on time and to a tight budget, with Anglo American extremely happy with the work undertaken and product supplied.

Key Pump Station Features:

  • All wiring / electrical installation & commissioning on these pump stations was undertaken by Major Electrical Pty Ltd
  • KROHNE flow meter
  • Pump station utilises four pressure transducers to feed real time pumping data to the computer control
  • Two vertical stage pumps directly coupled to two 45kW motors
  • As the booster pump station was dealing with high pressures all piping and flanges have a 3,000kPa rating
  • Pump station fitted with QDS (Quick Detachment System) lift points - allowing the station to be transferable via the underground Line Eimco
