Description
Pumps PEDROLLO of the line HF medium flow rate, are recommended for civil, agricultural and.
The PEDROLLO HF 51B has a range that varies from 50 to 300 litres per minute, with a prevalence from 17.2 to 5.4 metres.
The high yields achievable and the possibility of a continuous use make it beneficial to the use of this pump for the irrigation or rain, for the withdrawal of water from lakes, rivers, wells and for a wide range of industrial uses that are characterized by the need to achieve large flow in the prevalence ratio low-medium
The installation is to be carried out indoors or otherwise protected from the weather.
