Full Description

Product overview

The Pedrollo PQ 81-Bs is a 0.55 kW (0.75 HP) peripheral pump on a 400 V three-phase supply, covering 1 to 24 l/min with a working head of 92 m down to 5 m. The peripheral (turbine) impeller builds pressure in a single stage, so the pump is compact and simple.

PQ pumps suit small domestic pressure sets, boiler feed, transfer and washing duties with clean water, and the Bs (brass body) and PPS versions extend the range to liquids that would attack cast iron. Install indoors or under cover.

Frequently asked questions

Is it self-priming?

No. It needs a flooded suction or a foot valve. The PKS range is the self-priming peripheral pump.

What is the Bs version?

The same pump with a brass body instead of cast iron, for softened water and liquids that would corrode cast iron.

What is the PPS version?

A pump body in PPS technopolymer with threaded brass inserts instead of cast iron, with the same brass impeller.

What water can it handle?

Clean water without abrasive particles; peripheral impellers have tight clearances and do not tolerate grit.
