HFm 5B - centrifugal electric Pump, single phase
Flow rate up to 500 l/min (30 m3/h). Head up to 13.2 m. Motor 0.75 Kw (1 HP).



Pumps PEDROLLO of the line HF medium flow rate, are recommended for civil, agricultural and.
The PEDROLLO HF 5B has a flow rate that varies from 100 to 500 litres per minute with a prevalence from 13.2 to 5 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.
