Ingersoll Rand / ARO piston pumps are an ideal solution for pumping motor oil, gear oil, and transmission fluid. Our LM Series pumps are available in 3:1 (2" Diameter Air Motor) and 5:1 (3" Diameter Air Motor) ratios. The older model Series 200 pumps are designed for industrial applications that require 1:1 ratio pumps. The Series 425 pumps use a 4 1/4" air motor to pump products with a 9:1 ratio.
Our LM Series Pumps offer the following advantages:
* Stall-free, ice-free air motor
* In-line serviceability for 3:1 models
* All weather pumping
* Quiet Operation
