NKV 65/6-2 T Multistage centrifugal pump DAB.NKV

Product detailed description

The NKV 32,45,65,95 series pumps in AISI 304 stainless steel are vertical centrifugal pumps with coupling designed for pressurization in domestic and commercial environments, 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 are in contact with the liquid are made of AISI 304 stainless steel (AISI 316 version X, on request only). From TYPES with 5,5 kW output, the mechanical seal is removable without dismantling the motor. Mechanical seals for aggressive liquids and different connections (round, oval, Victaulic, clamping flanges) on request. All TYPES are WRAS and ACS certified for use with potable water.
