KsD Series Between-Bearings Three-Stage Axially Split Pumps with the Double Entry First Stage
Applications: Designed for handling condensate in the steam and water circuit systems of the thermal power stations that burn organic fuel. May be also used in hot water heating and water supply systems and in metallurgy.
Design: KsD series pump units consist of a centrifugal pump, an induction motor, a rubber-bushed (pin-and-bushing) flexible coupling with a coupling guard, which are mounted on a common fabricated base plate.
The pump units shall be rigidly anchored to the foundation, and piping shall be rigidly connected to the pumps.
Electrically driven horizontal foot-mounted, three-stage axially split volute casing centrifugal pumps with the first stage double entry radial impeller. The pump casing is a locating part of the pumps, which incorporates a lower and an upper casing halves bolted together by means of studs. A flanged suction nozzle is integrally cast with the lower casing half and is oriented vertically to the bottom and a discharge one, horizontally perpendicular to the shaft centerline.
The pump rotor is carried by the oil-ring lubricated antifriction bearings with oil bath.
Shaft sealing: packed glands.
Sense of rotation of shaft in all the pumps is counterclockwise, if viewed from the drive side.
