Aro/ingersoll-rand LM2203A-41-C Air-operated Pump 6 Gpm

Product Description

The ARO/INGERSOLL-RAND LM2203A-41-C is an air-operated fluid transfer pump designed for dispensing gear oil, motor oil, and transmission fluid from 55-gallon drums and larger containers. Built with a carbon steel pump body and operating on a 3:1 ratio, it delivers a rated flow of 6 GPM and a free-flow rate of 9 GPM. Maximum operating pressure is 450 psi. A 1/4-inch air inlet and 1/2-inch outlet thread connection make integration into existing lube room and service bay plumbing straightforward. Licensed HVAC techs, fleet mechanics, and lube technicians are the typical installers.

This pump is suited for stationary or portable dispensing setups in commercial garages, fleet maintenance facilities, and industrial lube rooms. It is compatible with 55-gallon drums and containers 400 pounds or larger. Typical applications include bulk gear oil transfers, motor oil fills, and transmission fluid dispensing where a reliable, air-driven solution is required in place of manual pumping. The 3:1 pressure ratio allows consistent delivery across viscous petroleum-based fluids without requiring high input air pressure.

Installation Notes

Installation should be performed by a qualified mechanic or fluid handling technician familiar with air-operated pump systems. Shut off and bleed the compressed air supply before connecting or disconnecting fittings. Verify air inlet and outlet thread sizes match existing lines before final assembly. Follow applicable OSHA and facility safety guidelines for petroleum fluid handling during installation and servicing.
