The High-Pressure Hand Grease Pump 200 Bar is a lever-operated, drum-suction hand pump that fills bearings directly from standard drums and pails, generating up to 200 bar (2,900 PSI / 20 MPa) at the outlet. It covers 12 – 50 kg drums, a 120 lb drum, and a 5 gallon pail through one strainer-fitted suction tube, with no cartridge to swap. With compressed air and repetitive, high-volume filling, see the pneumatic drum pump system design guide; this page stays with the manual lever pump.
200 Bar Drum Pump at a Glance
A hand lever drives a single-acting piston that draws grease from the drum, pressurizes it, and pushes it through a wire-braided hose to a 4-jaw hydraulic coupler on the bearing nipple. No external power or compressed air is needed.
| Item | Specification |
|---|---|
| Working pressure | 200 bar (2,900 PSI / 20 MPa) maximum output |
| Proof pressure | 300 bar stated against the 200 bar working figure |
| Output per stroke | 2 cc (2 mL) per lever stroke |
| Working pace | 30 – 40 strokes per minute, operator dependent |
| Suction inlet | Strainer-fitted suction tube for 12 – 50 kg drums, 120 lb drum, or 5 gallon pail |
| Outlet thread | 1/4″ NPT or BSPP female |
| High-pressure hose | 1.8 m (6 ft) x 1/4″ ID, wire braid reinforced, minimum burst pressure 600 bar |
| Coupler | 4-jaw hydraulic type, hardened alloy steel jaws, for 6.5 mm taper-head nipples |
How Grease Reaches the Bearing
The grease path runs in one straight line: Drum – Suction Tube – Piston Pump – High-Pressure Hose – 4-Jaw Coupler – Bearing Nipple. When delivery drops, check the chain in that order.
Drum Suction and Container Fit
The strainer-fitted suction tube draws grease and keeps debris out. It fits 12 kg, 20 kg, and 50 kg drums, a 120 lb drum, and a 5 gallon pail. Name your drum size when ordering so the tube matches.
Output per Stroke and Working Pace
Every lever stroke moves a fixed 2 cc (2 mL). A typical working pace is 30 – 40 strokes per minute, operator dependent; under sustained, continuous stroking the theoretical maximum output is 60 – 80 mL/min.
Operating Notes for Field Use
Cold grease raises suction resistance. With NLGI 2 in a cold drum the lever turns heavier as the grease stiffens; that heavier lever is a signal to adjust the setup, not a pump fault.
Honest Limitations of a Manual Pump
This manual lever pump has real boundaries:
- No motor or air drive: with shop air and repetitive, high-volume filling, a pneumatic drum pump fits better; see the pneumatic drum pump system design guide.
- Output follows the operator: continuous heavy filling at pace demands steady lever work, and breaks in rhythm lower real delivery.

Frequently Asked Questions
Pneumatic drum pump or this manual pump – how do I choose?
Air supply and workload draw the line: a manual pump fits field maintenance and single-point filling with no shop air on site, at low purchase cost; a pneumatic drum pump fits repeated, high-volume filling where air is available.
What does the 200 bar figure actually mean?
200 bar is the maximum pressure the pump generates at its outlet; pressure at the bearing is limited by the lowest-rated part in the chain: hose, coupler, or fitting. The 300 bar proof pressure is a factory verification figure, not an operating pressure.
How much grease does the pump deliver per stroke?
One lever stroke delivers 2 cc (2 mL). A typical working pace is 30 – 40 strokes per minute, operator dependent; under sustained, continuous stroking the theoretical maximum output is 60 – 80 mL/min.
Which drums and pails does the suction tube fit?
It fits 12 kg, 20 kg, and 50 kg drums, a 120 lb drum, and a 5 gallon pail. Replacement tubes come in sizes for other drum diameters; name your drum size when ordering.
What if cold NLGI 2 grease is too stiff to pump?
In a cold drum NLGI 2 grease stiffens and the lever turns heavier as suction resistance rises: a signal to adjust the setup, not a pump fault. Warm the drum or move to a softer grade.
What if the coupler will not release from the nipple?
Release the pressure first: trapped grease keeps the 4-jaw coupler clamped on the nipple, and pulling against pressure locks it harder. Stop stroking, release at the pump or hose connection, and it comes free.
Why has the pump stopped drawing grease?
Suspect a clogged strainer, a nearly empty drum, or a loose suction-side joint drawing air. Clean the strainer, confirm the drum level, tighten suspect joints, and try again.
What coupler does the pump use?
A 4-jaw hydraulic type with hardened alloy steel jaws. It locks onto standard 6.5 mm taper-head nipples built to DIN 71412 and connects to the 1/4″ hose end fitting.
How do I get replacement seals or spare parts?
Seal kits, replacement suction tubes, and strainer screens are available. Give the pump model when ordering so the right parts ship, or send us your pump model.
