Positive displacement pump flow control

[kmpillai]

Hi all,
I am having a small Positive dispalcement lubricating oil pump with 2 outlets, one is a return line (connected to the tank) and other is connected to the part to be lubricated. I would like to control the flow of this line from 25 % to 100 % at constant speed. Kindly advice.

Advance thanks
KMP

Adding complexity to a lube oil system also adds failure modes, which is not generally a good idea.

What problem are you actually trying to solve?

Look into three-port priority flow controls. Controlled flow out one port, excess flow out the second port.
