The PWR-Flo range is built on an asymmetrical spool design, and Nomad make no secret of the reason: it is one of the most air-efficient systems on the market. Compressed air is expensive to make, so a pump that does more work per cubic metre pays for itself over a shift pattern. PWR-Flo pumps cover sizes from 1/4 inch up to 3 inch, with flow reaching well over 800 litres a minute on the largest models. Maximum air supply pressure is 8.6 bar.
The other half of the asymmetrical spool story is reliability on stop-start work. Filling and batching duties cycle a pump constantly, and that is precisely where a marginal air valve will hang up mid-stroke and cost you a line stoppage. PWR-Flo is engineered to shift positively every time. The air valve and centre section are moulded in chemically resistant polypropylene, which also stands up well to aggressive atmospheres around the pump itself.
Wetted bodies are offered in aluminium, cast iron, 316 stainless steel and polypropylene, with centre sections in aluminium or polypropylene. Diaphragms cover nitrile, EPDM, neoprene, FKM, polyurethane, Santoprene, TPE and PTFE, plus PTFE-faced combinations and one-piece integral piston versions. Porting comes in BSP, NPT, flanged and Tri-Clamp, and many of the pumps listed carry an ATEX rating.

It is the air distribution system at the heart of every PWR-Flo pump. The asymmetrical spool arrangement is engineered to deliver a highly efficient air system while positively preventing the pump from stalling mid-stroke. In practical terms that means lower compressed air consumption and dependable restarting on repeated on-off duties.
Yes, that is one of their strongest use cases. The anti-stalling design gives reliable performance in repeated on-off liquid transfer, which is exactly what filling and batching operations demand. If your process starts and stops the pump hundreds of times a shift, this range is worth a close look.
The PWR-Flo pumpscome in aluminium, cast iron, 316 stainless steel and polypropylene wetted bodies. Aluminium is the general-purpose default, cast iron suits abrasive heavy duty, stainless steel handles corrosive and hygienic media, and polypropylene is there for aggressive chemistry.
Many pumps in this category carry an ATEX rating. If you need a pump for a zoned area, filter by certification or contact our team with your zone and equipment category requirements and we will identify the right build codes.
