A question about engine prelube pumps
A question about engine prelube pumps
(OP)
I tried the google thing and get no where with it.
Looking for a motor driven geroter or similar pump to prelube a large gasoline engine. Something regulated to say 40 psi, and the oil is equivalent to SAE 60.
Anyone know where to look for one?
Thanks.

Made a simple control circuit that when you turned the key to crank the engine, the pump came on and when pressure built, a Hobbs switch closed and allowed engine crank, a bypass button was installed so if you needed to start right away or the engine oil was hot you could bypass the Hobbs switch and crank. The pump control circuit was interlocked so you could not run the pump with the engine running.
If it's a turbocharged engine you may want to consider adding the ability to do post lube for a short duration as well.

An I-R air motor, MVA017B, which has a keyed 5/8" shaft,
and a Viking internal gear pump, which has a 5/8" female keyed hole in its center. It appears to be a custom part for Waukesha, and bears part number WED-208478.
They just bolt to each other around a piloted flange; no coupling required.
