Description
Davey HP45-05T HP Series Pump with Torrium2
Small pumps designed for tight spots
The lifestyle series HP water pressure systems with Torrium2 offers perfect water pressure with a small water pump that can fit into a tight spot.
The HP water pressure systems have been certified and tested to comply with the requirements of the AS/NZS 4020 standard. The AS/NZS 4020 standard stipulates that products in contact with drinking water do not affect the taste or appearance of the water, do not support the growth of micro-organisms and do not release cytotoxic or mutagenic compounds or metals into the water.
Applications
Ideal for pumping clean, non-volatile liquids without fibres or solids in such applications as household water supply, irrigation, water transfer, washing systems and pressure boosting.
The HP Series Pressure Systems, consist of an HP pump fitted with a Torrium2 controller. The Torrium2 is supplied connected electrically to the HP pump motor for:
- Easy non-tradesmen installation and assembly
- Positive safety under varied weather conditions
The combination of the high pressures supplied by the HP pump and constant flow control provided by the Torrium2, enables consumers to enjoy the benefits of a strong comfortable shower from a pump that does not cycle, plus the reliability of adaptive technology.
The complete HP Pressure System is compact and quiet providing for:
- Easy installation, especially where space is at a premium
- Non-intrusive operation, for consumer enjoyment
All parts of the entire system that are in contact with the water are manufactured from safe, corrosion-resistant materials for:
- Consumer confidence that their water supply will be as good coming out as it was going into the system
- Ability to use the HP pressure system on a variety of water qualities
Pump
- Reliable twin stage impeller design
- All stainless steel construction for reliability and the ability to pump hot water up to 50°C
- Carbon/Ceramic mechanical seal for reliable pump operation
Motor
- TEFC motor constructed from corrosion-resistant materials
- IP55 international protection rating for a high level of resistance to dust and liquid entry.
- Voltage variants:
- 220-240V, 50Hz, 2 pole
- 220V, 60Hz, 2 pole (/P models)
- Class F insulation
- Higher than normal 50°C ambient temperature rating for longer life and improved tolerance to voltage variations for peace of mind, even on the hottest days.
- Protected against both high operating temperature and high current draw by a built-in, automatically re-setting, thermal overload
- Permanently split P2 ‘fail safe’ capacitor design
- Motor and pump are designed for frequent starts

Installation & Priming
- Installations with suction lift require a good quality foot valve to avoid loss of prime – remove in-built check valve.
- To prime, fill pump body and suction line through priming plug hole located above suction inlet and replace plug
