PM45 - 40:1 pump system with pump hoist and gravity follower plate for 185 kg drums. Includes pump 531 410 and hose connection kit Part No. 534 414. Includes drum retainers. Needs to be secured to the floor. Dimensions: 800 x 900 x 36 mm. PumpMaster 45 grease pumps mounted onto a gravity fed follower plate and an air operated pump hoist for use with 185 kg drums. The air operated pump hoist lifts and lowers the pump, making drums changes easier, faster and safer. The pump lower end is rigidly fixed to a follower plate with a single rubber lip. The weight of the pump, pump bracket and follower plate plus the atmospheric pressure push the assembly against the fluid eliminating channelling and air pocket, keeping lubricant free from contaminants, minimizing waste and aiding pump priming.
