Oil Pump Selection Guide

Pressure Ratio 1:1

P/N 32091, 32095, 32071, 32072 and D.D. Pumps

The 1:1 piston pumps are an economical way to transfer new engine oil, hydraulic fluid, transmission fluid and 100% antifreeze for distances of approximately 100 ft. or less. Maximum output pressure is 120 PSI.

Double Diaphragm pumps are ideal for transfer of used oil, as well as fluids mentioned above.

Pressure Ratio 3:1

P/N 20001T, 20073T and 20094T

An excellent choice for pumping engine oil, gear oil, hydraulic fluid, transmission fluid and antifreeze over distances of up to 150 ft. These pumps will service several dispensing points simultaneously. Maximum output pressure is 360 PSI.

Pressure Ratio 5:1

P/N 21100T, 21073T and 21094T

These pumps will do everything the 1:1 and 3:1 pumps do, but can be used to transfer fluid up to 200 ft. and will still service several dispensing points simultaneously. Maximum fluid pressure output is 600 PSI.

High Volume 5:1 Ratio Pumps

P/N 21200 and 21300

These pumps also have a maximum fluid pressure output of 600 PSI but have flow rates more than twice the output of normal 5:1 pumps. These pumps are an excellent choice for high flow applications in truck shops or industry where multiple dispense points are required.

High Ratio Oil Pumps

P/N 21400 and 21500

Higher ratio oil pumps provide additional capability when dealing with long distance oil dispensing, higher viscosities, unusual line restrictions or a combination of these factors. The 21400 pump is a 8:1 ratio pump with flow rates up to 5.5 GPM while the 21500 is a 13:1 ratio pump with a flow rate of 4 GPM. These are both universal stub pumps that can be easily adapted to fit most any tank or drum application.
