Description

The Pedrollo HF 50A centrifugal electric pump is suitable for those who require high flow rates at the expense of head.

Recommended for use in the agricultural and industrial sectors, particularly for surface and sprinkler irrigation, and for drawing water from lakes, rivers and wells.

Advantageous as it is reliable and constant even during long watering sessions.

Pedrollo has created a solid and robust product: the HF 50A is made from materials such as cast iron and AISI 304 and 431 stainless steel.

The flow rate ranges from 50 to 300 litres per minute while the head ranges from 6 to 12 metres.
