Alemite 7538-4 Lever Hand Grease Pump 500 Psi

Product Description

The ALEMITE 7538-4 is a lever-operated hand pump designed for grease lubrication applications in industrial and commercial maintenance environments. Built from steel, aluminum, and stainless steel, it delivers up to 500 psi of operating pressure, making it suitable for high-resistance grease fittings and long-line delivery setups. Weighing 19 pounds, the unit is robust enough for shop and field use. It ships as a complete assembly, including a cover, flexible follower, loader coupler, and loader extension, so it is ready to put into service without sourcing additional components. Licensed mechanics, lubrication technicians, and industrial maintenance crews are the primary installers.

This pump is configured for use with 120 lb grease containers and is rated for compatible container sizes ranging from 40 to 399.9 lb. It suits stationary shop installations and mobile lube truck setups where bulk grease dispensing is required. The lever-action mechanism provides mechanical advantage for consistent output pressure across a range of grease viscosities. It is commonly used in fleet maintenance, heavy equipment servicing, and manufacturing facilities where high-volume grease lubrication is a routine task.

Installation Notes

Installation is typically performed by lubrication technicians or industrial maintenance mechanics. Before mounting, relieve any residual pressure in existing lube lines and ensure the container is seated on a stable, level surface. Follow the equipment manufacturer guidelines and applicable OSHA lockout/tagout procedures when servicing pressurized lubrication systems. Do not exceed the 500 psi rated operating pressure of this pump.
