GENERAL DESCRIPTION
The Aro 2’’ differential 1:1 ratio transfer pumps are intended to be used primarily for oil transfer and delivery systems. It is best to use this pump with low - medium viscosity fluids. It uses carbon steel and other materi- als which make it compatible with most petroleum based lubrication products.
