Sense of rotation viewed from driverR : RightL : LeftDischarge Flange (D)

Suction Flange (S)Sense of rotation (R/L)

In standard production coupling is on the suction side and direction of rotation is clockwise viewed from driver end ( R 3 / 0 ). Flanges in parallel on the same direction are only possible with 3 or more stages for sizes from 32 to 125.

Bearing TypeSuction Discharge

• 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.

Rotation

• Pump shaft is supported by grease lubricated

rolling bearings. Pumps with oil lubricated bearings

are produced on special request.

Bearings

• In standart production soft packed stuffing

boxes are used for temperatures up to 110 °C. For

temperatures above 110 °C up to 140 °C cooled

soft packed stuffing boxes are used. Depending

on customer requirement mechanical seals are

applicable.
