Speroni CS 40 is a monobloc centrifugal electric pump with the pump body connected to the motor via a support. It also has flanged suction and delivery ports (PN 10) and threaded counterflanges . This electric pump is suitable for pumping clean water and other chemically and mechanically non-aggressive liquids. It can also be installed in any position , except for those with the suction port facing upwards.
This Speroni CS 40 electric pump is equipped with a three-phase IE3 motor , a high-efficiency electric motor that complies with the IE3 energy efficiency class according to the international standard IEC 60034-30 . An IE3 motor consumes less energy than an IE2 or IE1 motor to produce the same power.

Suitable for the most varied needs in the civil , agricultural , industrial or general plant engineering fields, water supplies , sprinkler or flow irrigation, autoclave feeds and pressure boosters , heating and air conditioning, any other use that involves the transfer of clean liquids in general.

Speroni CS 40 can vacuum liquids up to 35°C (domestic use according to EN 60335-2-41 ) from a height of up to 7 metres , and up to 90°C for other uses. It also operates at a maximum ambient temperature of 40°C in continuous operation. CS 40 is equipped with a 2-pole induction electric motor (n = 2850 min-1), insulation class F and IP 55 protection.
