The NKV 32, 45, 65, 95 range of pumps made of AISI 304 stainless steel are vertical centrifugal pumps with a coupling, designed for pressure boosting in residential and commercial settings; they can also be used in agriculture and irrigation systems. The pumps can be used for water circulation in heating and air-conditioning systems. The parts of the pump that come into contact with the liquid are made of AISI 304 stainless steel (AISI 316 version X, on request only). From TYPES with an output of 5.5 kW, the mechanical seal can be removed without dismantling the motor. Mechanical seals for aggressive liquids and various connections (round, oval, Victaulic, clamp flanges) are available on request. All TYPES are WRAS and ACS certified for use with drinking water.
