Gear Pumps FAQ

Q - Can I run your pumps in reverse?
A - You can run all gear pumps except GP-201A in both directions without causing damage or shortening the service life of the pump.

They can be wired to a reversing switch


Q - Do I need to prime your pump before use?
A - You may have to prime the pump initially. After that they do not need to be primed for subsequent use. In most cases where the pump has problems with priming, there is an air leak on the pick-up side of the hoses.

Q - Will the pump handle debris coming from the oil pan or the fuel tank ?
A - All pumps will handle any organic contaminants usually found in fuel and oil tanks. If you are concerned about bigger particles, (sand, metal shavings, etc.) you should consider installing in line stainless steel strainer.

Q - What size hose should I use to connect my oil change system?
A - We recommend a minimum of 1/2” ID hose or piping for all runs under 10 feet, and 5/8” ID or larger for longer runs. Use only high quality Type-A petroleum resistant hose.

Q - Can I pump fuel with your pumps?
A - Our pumps are NOT rated for gasoline. You can pump diesel fuel and oil with the gear pumps.

Q - Can your pumps be mounted in any orientation?
A - Our pumps will work in any orientation.
