Description
Pumps PEDROLLO of the line HF high flow rates, are recommended for civil, agricultural and.
The PEDROLLO HF 20B has a range that varies from 400 to 1700 liters per minute, with a prevalence from 15.5 to 2 meters.
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.
