• It is good practice to clean your pump on a regular basis as
this will normally increase the life of your pump greatly.
• Vane wear should be checked every 12 months. A new

• When vane wear exceeds 1/4” the vanes should be
replaced. It is a good idea to have an extra set of vanes,
seals and gaskets on hand at all times.
Determining the rotation of the pump
As one faces the drive end of the pump:
• For 1000 RPM pumps with the oiler on the right side, the
pump shaft turns clockwise.
• For gear driven pumps (540 RPM) with the oiler on the right
side, the pump shaft turns counterclockwise.
• If you must change the rotation of your pump contact the
factory for instructions before attempting it.
