Alemite 9961-1 Air-operated Oil Pump 4 Gpm 5:1 Ratio

Product Description

The ALEMITE 9961-1 is an air-operated drum pump designed for dispensing oil and petroleum-based fluids from 120-pound or 16-gallon containers. Built with a steel, aluminum, and stainless steel construction, it delivers a flow rate of 4 GPM at a 5:1 pump ratio. The 1/4 NPTF female air inlet connects directly to a shop air supply, and the 1/2-inch hose diameter supports steady, controlled fluid transfer. This unit ships as a complete kit, including a 5.5-foot material hose, control valve, drum cover, inline electronic meter, and steel dolly. It is intended for installation and use by lubrication technicians, fleet maintenance crews, and industrial service professionals.

The 9961-1 is suited for use in automotive shops, fleet service bays, manufacturing facilities, and industrial maintenance environments where controlled dispensing of lubricants is required. Compatible fluids include cutting oil, gear oil, hydraulic oil, machine coolants, motor oil, petroleum-based fluids, and transmission fluid. The unit is designed for use with 120-pound drums and 16-gallon containers, covering a compatible container size range of 40 to 399.9 pounds. The included steel dolly and drum cover support organized, stationary drum setups.

Installation Notes

Installation is performed by lubrication technicians or maintenance professionals familiar with drum pump systems. Before connecting to the air supply, confirm the shop air pressure is within the pump manufacturer's specified operating range and that all fluid line connections are secure. The air inlet requires a 1/4 NPTF female connection — use appropriate thread sealant and verify the fitting is fully seated before operation. Always relieve air pressure from the system before servicing or disconnecting any component.
