Wilden Pro-Flo Pumps
As the industry's workhorse, the Wilden Pro-Flo® Series combines elegant simplicity with robust and reliable performance that end users have come to depend on for more than 20 years.
The Wilden Pro-Flo® SHIFT (PS Series) sets a new standard in air-operated double-diaphragm (AODD) pump efficiency and reliability. Engineered by Wilden, a PSG Dover brand, it delivers up to 60% air savings and 34% higher flow rates compared to conventional AODD pumps. Ideal for chemical, industrial, hygienic and wastewater applications, the Pro-Flo SHIFT is designed for low energy use, high throughput, and simple maintenance.
Pro-Flo SHIFT Air Distribution System (ADS)
A patented air-control spool optimises air flow, eliminating over-charging and stalling while delivering full-stroke performance. The result: maximum productivity with minimum air consumption.
Streamlined Flow Path
Optimised wetted-chamber geometry ensures smooth flow, high suction lift, and efficient solids handling.
Durable Design
Few moving parts and corrosion-resistant materials mean longer service life and less downtime. Available in metal (aluminium, stainless steel, alloy C) or plastic (PP, PVDF) constructions with bolted or clamped configurations.
