Designed for forced circulation of superheated boiler water within a closed-circuit systems in the exhaust-heat boilers. May be also used for handling liquids similar to the same in viscosity and chemical activity.

Description:

KO series pump units consist of a centrifugal pump and an induction motor, which are connected by means of a rubber-bushed (pin-and-bushing) flexible coupling and mounted on a common fabricated base plate.

The pumps are electrically driven, horizontal, centreline-supported, back pull-out, radially-split, single stage volute-casing centrifugal pumps with overhung impeller and bearing pedestal.

Flanged suction and discharge nozzles integrally cast with the pump casing are vertically to the top.

A casing cover is provided with a thermal barrier chamber.

The pump rotor is carried by oil-bath lubricated antifriction bearings. Inner space of the bearing pedestal serves as their oil sump. The design provides for its cooling with liquid supplied into a special chamber of the bearing pedestal.

Shaft sealing: stuffing box (packed gland) fed with cooling and sealing liquid from an external source.
