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 materi­als which make it compatible with most petroleum based lubrication
products.
