Lincoln 4417 Air-operated Grease Pump 40:1 4000 Psi Aluminum

Product Description

The LINCOLN 4417 is an air-operated grease pump designed for high-volume lubrication service in industrial and fleet maintenance environments. Operating at a 40:1 pump ratio, it delivers up to 5 cubic inches per minute of grease flow and reaches a maximum operating pressure of 4000 psi (413 bar). The pump body is constructed from aluminum, keeping weight manageable while resisting corrosion in shop environments. This unit ships as a complete kit, including a 7-foot connecting hose, band dolly, coupler, drum cover, follower plate, high-pressure control valve, and universal swivel, giving technicians everything needed to get a drum station running quickly.

The 4417 is sized for 120-pound grease drums and is compatible with containers ranging from 40 to 399.9 pounds. It is well-suited for automotive service bays, heavy equipment shops, and fleet maintenance facilities where centralized grease dispensing from a drum is standard practice. Licensed mechanics and lube technicians are the primary installers, typically integrating this pump into a fixed or mobile drum cart station fed by compressed air.

Installation Notes

Installation is typically performed by a licensed mechanic or lubrication equipment technician. Disconnect and bleed the air supply before servicing any fittings or changing the drum. Ensure the follower plate seats squarely on the grease surface before pressurizing to prevent air entrainment in the pump. Verify all high-pressure hose connections are rated for 4000 psi before putting the system into service.
