Pedrollo PQ Series Electrobombas with Peripheral Impeller
A new version with reduced noise level by 20%.
Performance Field
- Flow rate up to 90 l/min (5.4 m³/h)
- Head up to 100 m
Uses and Installations
Peripheral electrobomba with radial suction. Recommended for pumping clean water without abrasive particles and liquids that are chemically non-aggressive to the pump materials. The hydraulic characteristics of these pumps, combined with their compact size, suggest their use in the domestic sector.
Limits of Use
