Pedrollo PQ-BS Pumps with Peripheral Impeller

Description

Pedrollo PQ-BS Pumps with Peripheral Impeller – Side Suction

INSTALLATION & USE

The PQ-BS (Brass Body) Pumps with Peripheral Impeller are designed to suit a wide range of applications, with features including:

– High heads achieved from low motor powers
– Small variations in delivery rates in the event of changes in the pressure demand
– High tolerance to entrained air in the pumped liquid

Designed for pumping diesel/naphtha and clean water free from abrasive particles and non-corrosive liquids that do not harm the pump’s components.
Their hydraulic characteristics, compactness, and small size make them ideal for industrial applications such as chillers, air conditioners, coolers, and boiler feed systems.

We always recommend getting pumps installed by a qualified plumber.
The pump should be installed in an enclosed environment or sheltered from inclement weather.

COMMON APPLICATIONS

For use in water supply systems, air conditioning systems, washing systems, pressurisation filler units, pressurisation sets, cooling systems, ironing system, and as irrigation pumps.

The Pedrollo PQm81-BS can be used as replacement pumps in Flamco Flexfiller, Armstrong 3750 Pressurisation Units & Lowara Presfix Pressurisation Sets.
