In 1955, Jim Wilden revolutionized the pumping industry when he invented the air-operated double-diaphragm (aodd) pump.
Since that time, Wilden® Pump & Engineering Company has forged a long-lasting legacy as the global leader in AODD pump technology. Thanks to a dedication to pioneering new innovations while providing unparalleled excellence in customer satisfaction, our family of AODD pumps is unmatched in reliability, durability, efficiency, and performance.
The Wilden pump range can be found successfully operating in various market and industry segments. Wilden is a world leader in AODD pumping technology and innovation constantly pushing the boundaries of what is possible with air-operated pumps.
The Wilden® Pro-Flo® SHIFT (PS) is the industry’s premier air distribution system (ADS) and your ideal solution to increase productivity, lower energy consumption, reduce air consumption and simplify maintenance. With design benefits unmatched by any other ADS on the market, the innovative, yet simple PS features an air control spool that automatically optimizes air consumption and eliminates overfilling of the air chamber with no reduction in flow rate.
This design conserves energy while maximizing mean time between repair (MTBR) for your air-operated double-diaphragm (AODD) pump. Ideally suited for a wide variety of industrial applications, the PS is your go-to solution to maximize productivity and lower costs.
Pro-Flo® SHIFT Design
A new generation of air distribution systems (ADS) has been designed to eliminate overfilling in AODD pump operation. One such ADS is the Wilden Pro-Flo® SHIFT, which restricts the airflow into the air chamber near the end of each pump stroke so that only enough air is introduced to keep the pumping process going. This is accomplished through the incorporation of an air control spool that automatically optimizes air consumption and eliminates overfilling of the air chamber with no reduction in flow rate.
Features and benefits of the Pro-Flo SHIFT ADS include:
Thanks to the incorporation of the Pro-Flo SHIFT ADS, Wilden PS Series pumps have some of the highest flow rates in the industry while costing less to operate.
Features and benefits of Pro-Flo include:
These FAQs will help — from how AODD pumps work and the energy-saving Pro-Flo SHIFT technology, to handling abrasive fluids and installation requirements. Discover why Wilden leads the industry and how Dowdens’ Queensland team can help you choose, install, and maintain the right pump.

The Wilden® SafeGuard™ is the industry’s first AODD Internet of Things (IoT) enabled remote performance monitoring and alert solution. It is a true game-changer in optimizing AODD pump performance, reliability, cost of operation and maintenance. SafeGuard is an all-inclusive monitoring system that tracks, records and alerts customers to key AODD pump performance indicators at all times of operation via continuous Cloud connectivity as a way to address and prevent operational shortcomings that can result in costly pump failures.
Why is pump monitoring so important?
Unexpected pump failures can be devastating for an operation and could result in much larger issues, including the high cost of downtime, repairs, lost product and product cleanup. This makes monitoring and anticipating potential AODD failure conditions a critical consideration for facility operators.
Wilden SafeGuard is designed to monitor Wilden AODD pumps’ health and performance. It is composed of a single battery-powered sensor (Edge Device) mounted directly onto the pump which communicates to a sensor reader (Gateway Node). The Gateway Node, which can connect up to 10 Edge Devices/Pumps, operates as an encryption router, securely transmitting the data from all pumps to the Cloud. Once stored on the Cloud, real-time and historic operational information can be accessed by the user anywhere in the world through a secure smartphone app or an online portal.
The design and operation of the SafeGuard system allows for complete 24/7 real-time monitoring and alerts related to a number of critical performance parameters for the pump (diaphragms, balls, seats). These readings can show the user such things as:
Wilden AODD pumps’ health and performance is displayed and summarized on the Wilden SafeGuard User Interface service where you can view the status of your whole fleet of connected pumps down to the details of a single pump. Capabilities include:
