SKM-DGeneral information

Handled Liquids :

SKM-D Type pumps are suitable for clean liquids with low viscosity.

Horizontal ring section multistage centrifugal

pumps with closed impellers and diffusers.

6 models from DN 65 to DN 200.

Suction nozzle flanges are according to DIN

2533 / PN 16 and discharge nozzle flanges are

according to DIN 2535 / PN 40 (DIN 2546 / PN

64).

In standart production suction flange is placed

on the right side and close to the coupling and

discharge flange is at the other end and at top.

Suction and discharge nozzle can be turned in

multiples of 90o.

Axial thrust is balanced by balancing disc.

In standard production coupling is on the

suction side and direction of rotation is clockwise

viewed from driver end. Pump driven from the

discharge side can be manufactured on special

request. In this case direction of rotation is

counter clockwise viewed from the driver end.

Pump shaft is supported by grease lubricated

NU type roller bearings.

Pump impellers are statically and dynamically

balanced.
