Follower Plate, Drum for PN: 11595 GRSPump,1:1,3:1,5:1 Pmps EA

The follower plate is pulled towards the bottom of the drum by the vacuum created by the pump operations and provides the following advantages.

• Keeps the grease clean and free of impurities.
• Compresses the grease which eliminates the formation of air pockets and possibly cavitation of the pump.
• Constructed of heavy duty materials with a double "O" ring seal on the I.D. to prevent air entrainment

For use with P/N 11595, 35:1 high volume grease pumps, 1:1, 3:1 and 5:1 oil pumps to fit 420 lb./55 gal. drums with I.D. between 21.3" and 22.8".
