The Pentax PM range is a family of peripheral positive displacement pumps designed for small household systems and simple industrial jobs. They’re valued for a strong ratio of performance to size, so a compact pump still delivers useful pressure and flow. Both cast iron and bronze body options are available depending on the model you choose.
PM pumps use a brass impeller and a ceramic-graphite mechanical seal, paired with a stainless steel motor shaft. Bronze-bodied models add extra corrosion resistance for more demanding water conditions. Every pump in the range uses a 1 inch outlet, keeping installation straightforward.
PM pumps handle liquid temperatures from 0°C right up to 90°C, so they cover cold mains boosting through to hot water circulation. Operating pressure runs up to 9 bar depending on the model. Both single-phase and three-phase motor options are available across the range.
