CPm 170-ST4 - Single-phase stainless steel centrifugal electric pump 1.5 HP
In AISI 304 stainless steel. Flow rate up to 140 l/min (8.4 m³/h). Head up to 41 m. 1.1 Kw (1.5 HP) motor.




It is recommended for pumping clean water and liquids that are not chemically aggressive towards the materials from which the pump is made.
Due to its construction features, this centrifugal pump is recommended for use in the domestic, agricultural and industrial sectors.
All components in contact with the pumped liquid are made of AISI 304 or AISI 316L stainless steel to guarantee total hygiene and maximum resistance to corrosion.
Installation must be carried out indoors or in any case protected from the elements.
