KSB WKLn 32-6, high-pressure centrifugal pump

Horizontal high-pressure centrifugal pumps in ring sectional design, single- or multistage, vertically split suction, discharge and stage casings. 

Applications

For municipal and industrial water supply in water works, pressure boosting installations, irrigation and sprinkler plants; as boiler feed pumps and condensate pumps, cooling water and hot water circulation pumps; for high pressure water in hydraulic presses, as fire pumps etc.

Construction

Horizontal high pressure centrifugal pumps in ring sectional design, single- or multistage, vertically split suction, discharge and stage casings. The individual casing parts are sealed by O-rings and are clamped together by external tie bolts. The pump feet are cast integrally with the suction and discharge casings, and are arranged beneath the pump.

Bearings

The bearings are enclosed in two bearing housings, flanged onto each end of the pump. On the suction end of all pump sizes a cylindrical roller bearing with spacer sleeve is fitted; on the discharge side of 32 and 40 a deep groove ball bearing, 50 and up an angular ball bearing is fitted. The rotating assembly is hydraulically balanced by means of back vanes or balance holes at the rear of the impeller; the residual axial thrust being absorbed by a ball bearing at the discharge side.

Shaft Seal

The shaft is fitted with renewable protective sleeves in the region of the stuffing box. Uncooled soft-packed stuffing boxes are used for temperatures up to 110ºC. Uncooled mechanical seal up to 110ºC maximum.

Nozzle orientation

The suction nozzle is horizontal, right-hand side when viewed from driving end, and the discharge nozzle is top, vertical. The suction flange is machined according to DIN 2533, NP 16 or BS 4504 table 16/11. The discharge flange is machined according to DIN 2535, NP 40 or BS 4504 table 40/1.

Drive

Direct drive by electric motor through a flexible coupling. The suction end of the pump is the driving end, direction of rotation is clockwise; the shaft stub of the driver is fitted on the discharge side (direction of rotation is counterclockwise), or two shaft stubs can be provided, one at each end.
