Integral, multi-stage, submersible, centrifugal electric pumps for wells from 6” or open wells.

These have been designed for supplying clean water to homes, small farms, sprinkler irrigation systems and pressurisation equipment. 

All parts in contact with water are made of AISI 304 stainless steel, except for the spray nozzles, which are made of thermoplastic. The selected materials guarantee proven reliability and durability with drinking water. 

The motor is manufactured such as to allow effective cooling in the whole range of pumping flows, thanks to its double inner jacket and the special way the top sealing body and the double mechanical closure are achieved. 

The compact design of the pump allows effective cooling of the motor even when installed in open wells, tanks or ponds; it has also been designed so that its suction via the bottom enables better exhaustion of the suction tank. In drilling installations it allows the exploited dynamic level to be increased.
