Do I need an air regulator on my oil and grease pumps?
Yes, absolutely yes! Every oil and grease pump needs an air regulator. Too little air and the pump won’t pump. Too much air and the pump will wear out sooner and you will have control problems.
Pumps should be set somewhere between 60 PSI and 90 PSI. If you are running a thin product like ATF, then set your air regulator closer to the 60 PSI mark. But if you are running a thicker product like gear oil, then set your air pressure closer to the 90 PSI mark.
Finally, if your pipe runs are long, say over 150 feet and your output on the far end is slow, you can turn up the air pressure to push the extra distance.
Hope this helps!
