Follower Plate, 21.3" - 22.8" 420 lb, High Volume 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 11395, 80:1 high volume, high pressure grease pumps and 420 lb. drums with I.D. between 21.3" and 22.8".
