Product Information
Full details
This Draper high-pressure hand grease pump (43958) is designed for professionals and serious DIYers needing to apply grease efficiently to machinery and components. Its key benefit is delivering a consistent 1.2g of grease per stroke at high pressure (3500psi), ensuring thorough lubrication. A potential caveat is its suitability primarily for NLGI 2 grease and UK 12.5kg pails, requiring users to confirm compatibility with their existing supplies.

FAQs
What type of grease is recommended for this pump?
This Draper grease pump is designed for use with NLGI 2 grade greases.
What size grease pails does this pump fit?
It is compatible with UK 12.5kg grease pails.
How much grease does the pump deliver per stroke?
The pump delivers approximately 1.2 grams of grease per stroke.
What is the maximum pressure the pump can achieve?
The pump can achieve a maximum pressure of 24MPa, which is equivalent to 3500psi.
Does the pump come with a grease cartridge?
No, this is a hand grease pump designed to draw grease directly from a compatible grease pail. The grease pail and grease are sold separately.
How do I prime the pump?
To prime the pump, operate the lever several times until you feel resistance and grease begins to flow through the hose. This expels any air from the system.
What maintenance is required for the pump?
Regular cleaning with a dry cloth after use and proper storage in a clean, dry place are recommended. Inspect components for damage periodically.
Troubleshooting
Grease not being delivered
Ensure the pump is properly seated on the grease pail. Check for air locks by operating the pump lever rapidly for a few strokes. Verify the NLGI 2 grease is being used and that the pail is not empty. Inspect the suction tube for blockages.
Low pressure output
Check if the pump head or steel pumping chamber is damaged. Ensure the coupler is securely attached to the grease fitting and not leaking. The grease may be too thick or cold; try warming the pail slightly.
Hose or coupler leaking
Inspect the flexible hose for cracks or damage. Check the connection points of the hose to the pump and coupler. Ensure the four-jaw coupler is fully engaged on the grease fitting and that its seals are intact. Replace damaged components.
Pump difficult to operate
The grease may be too viscous or cold. Try warming the pail. Ensure the pump mechanism is clean and free of debris. Check for internal obstructions within the pump chamber.
