Description

The PEDROLLO pumps of the HF high flow rate line are recommended for civil and agricultural environments.

The PEDROLLO HF 20A has a flow rate ranging from 400 to 1800 litres per minute with a head from 18.5 to 2 metres.

The high achievable yields and the possibility of continuous use make the use of this electric pump advantageous for flow or rain irrigation, for drawing water from lakes, rivers, wells or for the most varied industrial uses characterised by the need to achieve considerable flow rates in a medium-low prevalence ratio.

Installation must be carried out indoors or in any case protected from the elements.
