The Pedrollo PQm 81-Bs electric pump is an update of the PQ series and is recommended for industrial use.
A unique feature of this pump is the construction of the pump body which in this case is made of brass.
This pump differs from the PQ series, in that the PQ series is for domestic use and the pump body of that series is made of steel.
The use of CW617N brass guarantees against the formation of rust and oxidation, which consequently allows the pump to last over time.
Thanks to its hydraulic characteristics, small size and compactness, the PQm 81-Bs allows for industrial use in very restricted areas in chillers, air conditioning, cooling or boiler power equipment.
Recommended for pumping clean water without abrasive particles and liquids that are chemically non-aggressive for the materials from which the pump is made.
The flow rate ranges from 2 to 20 liters per minute. The head ranges from 10 to 95 meters.
The PQm 81-Bs must be powered by a single-phase voltage, has a horsepower of 0.75 HP and the temperature of the liquid to be pumped ranges from -10 degrees centigrade up to +90.
