HFm 5ARM - 3 HP single-phase centrifugal electric pump
Flow rate up to 700 l/min (42 m³/h). Head up to 23.5 m. 2.2 Kw (3 HP) motor.




The Pedrollo HFm 5ARM submersible pump is recommended for use in the agricultural and industrial sectors.
It has a flow rate that varies from 100 to 700 litres per minute with a head of 23 to 10 metres.
It must be powered by a single-phase voltage, has a horsepower of 3 HP and the temperature of the liquid to be pumped ranges from -10 degrees centigrade up to +90.
The high efficiency and the possibility of continuous use make the HFm 5ARM advantageous for flow and sprinkler 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 relation to medium-low heads.
