Precision Air-Powered Grease-Dispensing Pumps


1 Grease Outlet	2 Grease Outlets

4 Grease Outlets	6 Grease Outlets

Powered by your air system, these dispensers release a precise amount of grease in timed intervals, so your machine will never have too much or too little. They’ll dispense the right amount even if changing temperatures affect the grease consistency. Back pressure doesn’t impact these dispensers either. But compared to motor-driven dispensers, they’re more complicated to set up. Besides your air system, you’ll need to attach a three-port solenoid valve and either a timer or programmable logic controller (PLC) to control the valve (all not included). If you use a PLC, they’ll prevent over-lubrication when your machine is down by only greasing when it’s running. This is useful for machines with intermittent downtime. Even without a PLC, you can manually cut off the flow without uninstalling the dispenser.

They’re modular, so install or remove pumps as your lubrication needs change. Each pump has mounting holes drilled through their body. Use a screwdriver to turn each pump’s flow-adjustment screw.

These dispensers don’t come with grease, so use the grease that’s best for your machine.

Air-Powered Container-Mount Grease Dispensers

Dispense from your drum or pail of grease using compressed air. Dispensers include a follower plate that moves down the inside of the container as the grease level drops to compress the grease and prevent vapor pockets. Containers not included.

Dispensers deliver grease at the same pressure as your existing grease system, up to the max. grease outlet pressure.

For 35 lb. Pail


Style A	Style B

With Booster Gun—Dispensers with a booster gun allow you to increase the pressure to the value listed for max. grease outlet pressure with booster.

Styles A and B—Styles A and B have a Z-swivel that connects the outlet hose to the gun and prevents the hose from kinking.

Air-Powered Pistol-Grip Grease Guns

Use compressed air to dispense grease. This gun has a pistol grip that allows for one-hand operation, so it’s better for lubricating hard-to-reach spots than a lever-grip gun. Pull the trigger using small strokes to deliver small amounts of grease; hold the trigger for a continuous flow. The gun has a spring guard on the nozzle to prevent kinking.

Air-Powered Oil Dispensers

Connect these dispensers to your air system to pressurize the oil in the reservoir and atomize the spray. Dual regulators allow you to adjust the pressure of the oil and the atomized spray. Add a spray valve (sold separately) to direct the flow of oil. A removable filter prevents valve blockage. They have NPTF (Dryseal) threads, which are compatible with NPT threads.
