Aro/ingersoll-rand LM2305A-11-B Air-operated Pump 6 Gpm

Product Description

The ARO/INGERSOLL-RAND LM2305A-11-B is an air-operated fluid transfer pump built for professional lubrication service applications. Operating on a 5:1 pump ratio, it delivers a rated flow of 6 GPM and a free flow of 9 GPM, making it well-suited for high-volume fluid dispensing in shop and fleet environments. The wetted components are constructed from carbon steel, providing durability when handling petroleum-based lubricants. This unit requires oil lubrication and is designed for installation and service by qualified technicians in automotive, industrial, or fleet maintenance settings.

This pump is intended for transferring gear oil, motor oil, and transmission fluid in both commercial and light industrial environments. A 1-1/2 inch air inlet thread connection and a 1/2 inch outlet thread connection allow integration with standard shop air supply lines and fluid delivery hoses. Typical installations include lube bays, service pits, and fluid dispensing stations where consistent, metered output is required for multiple fluid types.
