Pedrollo PQ Pumps with Peripheral Impeller – Side Suction

Description

Pedrollo PQ Pumps with Peripheral Impeller – Side Suction

INSTALLATION & USE

Peripheral pump with radial suction.
Designed to transfer clean water free from abrasive particles and liquids that will not damage the pump’s components. Its compact design and efficient hydraulic performance make it ideal for domestic applications.

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, pressure systems, cooling systems, ironing systems, and as irrigation pumps.
