Pump K290/30 and electric pump units based on it

The centrifugal cantilever pumps of K type and electric pump units on their basis are designed for pumping process water (except sea water), as well as other liquids similar to water in density, viscosity, chemical activity with pH=6...9, with the content of solid inclusions not more than 1% by weight, size not more than 0.2 mm.
K type pumps are centrifugal, horizontal, cantilever, with gland or mechanical shaft seal.
The pump casing is a cast iron casting with inlet and outlet connections, spiral-ring outlet and support legs. The inlet connection is located along the axis of rotation, the outlet connection is directed vertically upwards and is located in the same plane as the axis of rotation.
The impeller is centrifugal, one-way inlet, closed type. The liquid supply to the impeller is axial.
The pump shaft is driven by the electric motor through a sleeve-finger coupling. Other types of coupling can be used. The bearings are supported by two radial angular contact bearings or ra...
