►

Check / clean the suction strainer regularly.

To protect the pump from coarse contaminant particles there is a suction
strainer in the suction port. Clean the suction strainer regularly.

Suction strainer cleaning interval

The suction screen (2.42) has a much larger absorption capacity at a mesh
width of 300 µm.

Change interval

Suction strainer

- every 250 hours*
- at least monthly*
- at every filter change*

300 µm

*) For heavily contaminated fluid, the maintenance intervals shorten.
