Hi
Can anyone tell me the advantages/disadvantages of one vs. the other when used in a closed loop hydrostatic drive?
Is one more suitable for high torque/low speed like the 2000 ft-lb 400 rpm range?
How do the efficiencies generally compare?
Any information would be helpful.
Just to give a little more information, the pump drive shaft is attached to the engine with a flexible coupler.
Its actually a tandem piston pump so it has two pumps in one housing which drives a set of ground drive motors in a mobile unit.
The engine vibration is the driving acceleration at...
Thanks for replying.
The pump is bolted to a plate which is bolted to the engine flywheel housing so the two are inline.
There is no additional support for the pump, in hangs freely from the flywheel cover so the vibration accelerations from the engine are being amplified.

I have a hydraulic pump assembly mounted to a 4 cyl. engine which analysis shows 2nd order vibrations in excess of 5g at the pump CG.
Given this information, how can I determine how this affects pump duty cycle and durability.
