12L Foot Operated Grease Pump for High-Volume Workshop Use
The 12L Foot Operated Grease Pump is the large-capacity finisher of our foot-operated line, built for workshops that service fleets, agricultural machinery, construction equipment and production lines. With a 12 liter barrel (approximately 3 gallons), it reduces refill interruptions during long service sessions. The floor-standing body stays planted while you work, and the pedal drive leaves both hands free to hold the grease gun and coupler. For a broader view of how these units compare with other designs, see our guide to different types of lubrication pumps.
How Foot Operation Works
You stand at the pump, seat the coupler on the fitting with one hand, and press the pedal with your foot. Each pedal stroke displaces approximately 5 grams of grease into the 2 m high-pressure hose. Leg force replaces the repeated arm strokes of a hand lever pump, which keeps your upper body steady and helps the coupler stay seated on the fitting. The working range is 20-25 MPa, so the pump covers standard grease points on trucks, trailers, tractors and plant equipment without strain. Because both hands remain on the gun, you can guide the coupler squarely and move from one fitting to the next with less repositioning.

What Is Supplied
Each unit arrives as a complete floor-standing assembly: the 12 liter barrel, the foot pedal and pump mechanism, a 2 m high-pressure hose, and a grease gun. The fill opening accepts standard grease containers, and the follower plate helps push grease toward the pump inlet as the barrel empties. Everything needed to begin servicing is supplied, so you can fill, prime and start work. The unit is the large-capacity member of the foot operated grease pump range. If you are new to this type of equipment, our grease pump overview explains the main operating principles.
Moving the Pump Around a Workshop
At 11.5 kg net weight, the pump is manageable for one person, though a full barrel adds weight and you should move it with care. Wheels and a handle let you roll it between service bays, from the truck bay to the tractor shed, or out to a machine on the shop floor. The wide floor-standing base keeps the unit stable when you pull the hose sideways, which matters when you are reaching around a chassis or under a machine. Park it on level ground, apply steady foot pressure, and the barrel stays planted instead of tipping or sliding.
Grease Grades, Priming and Daily Care
The pump handles NLGI 0-2 greases. In cold weather, a softer grade in the NLGI 0-1 range flows more readily and primes faster; in warm shops, NLGI 2 works well for most fittings. To prime, fill the barrel, fit the follower plate, and pump the pedal slowly until grease appears at the gun. If the pump air-locks, pump a few slow strokes until grease flows steadily. Wipe the coupler after use, keep the hose coiled without sharp bends, and check the follower plate for a good seal. Replacement seals and valve parts are available for routine servicing; contact us for a quote to confirm coverage for your unit.

Frequently Asked Questions
What grease grades can this pump handle?
It handles NLGI 0-2 greases. In cold conditions, choose a softer grade for easier priming and smoother flow.
How much grease does one pedal stroke deliver?
Each pedal stroke delivers approximately 5 grams of grease. Output stays close to that figure under normal load.
Is 20-25 MPa the working pressure or the maximum?
20-25 MPa is the working range for normal operation. It is a working figure, not a peak rating.
What barrel does the pump use?
It uses a 12 liter barrel, approximately 3 gallons. The follower plate helps move grease toward the inlet.
Can one person move it when full?
Yes, one person can roll it using the wheels and handle. A full barrel adds weight, so move it carefully.
Does it come with a hose and grease gun?
Yes. The unit is supplied with a 2 m high-pressure hose and a grease gun.
How do I keep the pump from air-locking?
Fill the barrel, seat the follower plate, and pump slowly. If air locks, keep pumping slow strokes until grease flows.
Are replacement seals available?
Yes, replacement seals and valve parts are available. Contact us for a quote and tell us your pump details.
Is a foot pump better than a hand lever pump?
For high-volume work, foot operation keeps both hands on the gun and coupler. Hand lever pumps suit smaller jobs.
