Description, Care and Maintenance

Hydraulic Powered Centrifugal Pump

Grease cup instructions (Fig.5)

Fill the grease cup through the grease fitting with No. 2 lithium base grease until grease escapes from the
relief hole. Turn the grease cup arm counterclockwise until it is at the top of the stem; this will release the
spring to apply grease to the seal.

NOTE:

Some smoking and leakage may occur after installing

a new seal assembly. This should stop after the pump

has run a while and the lapped seal faces have seated

in.
