Westward 21EM09 Lever Grease Pump
The Westward 21EM09 is a lever-operated grease pump rated to 4000 PSI for dispensing lubricants up to NLGI grade 3. It suits maintenance technicians and machine-shop personnel who need high-pressure grease delivery from a portable unit. The aluminium, brass, nitrile and steel housing resists corrosion from compatible grease chemistries. This pump is not for buyers who require automated or battery-powered dispensing systems.
Installation and common issues
The pump connects to a grease reservoir via its standard inlet and is primed by operating the lever until flow is steady. Air pockets in the suction line are the most frequent cause of lost pressure; bleeding the line usually restores performance. Worn nitrile seals can admit air or leak grease, so inspect them if pressure drops unexpectedly. Over-tightening the lever pivot may bind the mechanism and reduce stroke efficiency.
Pre-order checks
Confirm that your grease inventory matches the NLGI 3 maximum viscosity rating stated for this pump. Verify that the reservoir or drum opening accepts the pump’s inlet dimensions without adapters. Ensure the application does not exceed the 4000 PSI pressure limit of the unit. Check local regulations for the Proposition 65 chemical warnings listed by the manufacturer before purchase.

Questions about this item
How do I confirm the pump reaches 4000 PSI after setup?
Operate the lever through its full stroke and feel for firm, consistent resistance at the nozzle; a steady, high-pressure grease stream without foaming indicates the pump is delivering its rated pressure.
What comes with the 21EM09 lever grease pump and what must I supply?
The pump body with aluminium, brass, nitrile and steel housing is included; you must supply NLGI 3 or lighter grease and a compatible coupler or hose for your application.
Which version of the Westward 21EM09 should I choose for NLGI 3 grease?
The single model listed handles grease up to and including NLGI 3, so no alternative capacity or version is required for that grade.
