has anyone used an orbit mtr as a pump? I have a few char Lynn motors that I would like to use a pump.In Principle it should work,but as the inlet pressure is ATM,I wonder.

What is ATM?

Yes but watch your inlet conditions very carefully. With atmospheric inlet you might be able to run this as a pump at half of its rated RPM.

Parker link said this, and other data.

Epicyclic Gear Motor
Epicyclic gear motors are also called orbit motors, gear ring motors or gerotor motors. Unlike gear motors, the orbit motor has very low oil leakage. The motor can produce large torques at very slow speeds (approximately 5 rpm).


Excerpt:

Conceptually, a hydraulic motor should be interchangeable with a hydraulic pump because it performs the opposite function - similar to the way a DC electric motor is theoretically interchangeable with a DC electrical generator. However, most hydraulic pumps cannot be used as hydraulic motors because they cannot be backdriven. Also, a hydraulic motor is usually designed for working pressure at both sides of the motor.[1]

This kind of motor can be used as a pump or motor.
