These pumps are recommended for the use of transferring low to high viscosity oil and similar for short through medium distances. The delivery capacity of a pump varies according to applications and combinations. The operating pressure may vary between a minimum of 29 PSI and a maximum of 116 PSI. The double-acting air operated pump ensures the delivery of a continuous and constant flow, suitable for installations on distribution facilities.

We recommend using filtered air to optimize the efficiency and the life of our air operated pumps.
