Gear Pump Volume Formula
Gear Pump Volume Formula
(OP)
Could some kind soul point me in the correct direction please.
I need to find the capacity of an automotive transmission gear pump, the engine driver gear measures 2.364" driven gear=1.694" gear width=.472" and dimension between centres =1.574"
The formula I have is for gears of equal OD
Thank you for any & all advice

RE: Gear Pump Volume Formula
Doesn't say anything about the output flow of the pump. Need to know the displacement of the pump, in^3/rev.
Need to know the speed of the driver gear.

Pump speed will be from 735 to 8820 rpm.
Can not calculate pump displacement from speed or gear ratio unless you know pump flow at a pump speed.
