Where the PKm handles small domestic jobs, the PQ series steps up for applications needing more pressure from a compact footprint — think elevated storage tanks, small industrial cooling loops, or air conditioning systems needing consistent low-flow, high-head performance.
Pedrollo PQ Series Pumps with Side-suction design — why it matters.
The PQ uses a side-suction peripheral design, rather than the end-suction layout found on the smaller PK series. This changes the inlet and outlet orientation on the pump body, which in turn allows for more flexible installation. In many installations, the pump head itself can be rotated to suit tight or awkward pipework layouts — a genuinely useful feature when retrofitting a pump into an existing system where pipe positioning isn’t ideal.
What the Pedrollo PQ pump is built for.
Like all peripheral pumps, the PQ isn’t a solids-handling unit — it’s engineered purely for clean water and non-aggressive liquids. The peripheral impeller design (fluid moved around the outer edge of the impeller, rather than through the center as in a centrifugal pump) trades flow volume for pressure. This makes the PQ especially well-suited to:
- Elevated water storage tanks need consistent pressure at low flow
- Small-scale air conditioning and cooling loop circulation
- Boiler feed and hot water recirculation systems
- OEM equipment requiring a compact, self-contained pressure source
- Small industrial processes needing steady, low-volume, high-pressure water
Why installers and OEM builders choose Pedrollo PQ pumps.
Its value lies in delivering high pressure from a small, energy-efficient motor. Because the PQ is compact and self-priming, it’s frequently specified by OEM equipment builders needing to integrate a pressure source directly into a larger machine or system, as well as by small-scale industrial installers who need pressure rather than raw volume. Combined with straightforward maintenance access and Pedrollo’s standard build quality, the PQ has become a reliable mid-tier choice between basic domestic peripheral pumps and larger, more expensive centrifugal alternatives
