Product Description

The LINCOLN 4489 is an air-operated grease pump designed for lubrication service in shop and fleet maintenance environments. Built with an aluminum pump body, it delivers a 40:1 pump ratio and a maximum operating pressure of 4000 psi, making it suitable for high-viscosity grease dispensing from drum or pail containers. The kit ships complete with a 7-foot connecting hose, band dolly, follower plate, coupler, handle, high-pressure control valve, pail cover, and universal swivel, giving a technician everything needed to begin service immediately. The air inlet is a 1/4 NPTF female connection. Total package weight is 20 pounds.

This pump is used in automotive, fleet, agricultural, and industrial maintenance settings where grease must be dispensed from large-format containers. It accommodates containers ranging from 25 to 50 pounds, covering standard shop pails and mid-size drums.
