Oil Inspection and Change Procedures

Oil Inspection

Remove the oil plug and take out a small

amount of oil. The oil can be extracted easily

by tilting the pump so that the oil plug faces

downward.

If the oil appears milky or intermixed with

water, a likely cause is a defective shaft sealing

device (i.e. mechanical seal), which requires

that the pump be disassembled and repaired.

Changing Oil

Remove the oil plug and drain the oil

completely. Pour a speciﬁed volume of oil into

the oil inlet.

Note:

The drained oil must be disposed of by waste disposal contractors in compliance with the

laws of the respective country in which the pump is being used.

The packing and the O-ring for the oil plug must be replaced with a new part at each oil

inspection and oil change.
