Is there a preferred method in mounting pumps for a hydraulic system?
A If possible, it is best to use a bell-housing to mount the pump to the motor. Mount the pump outside the reservoir, below the fluid level. On occasion pumps have to be replaced, externally mounted pumps facilitate simple and fast replacement. If the pumps are mounted internally in the reservoir, pump replacement becomes very time consuming and difficult for the maintenance personnel to work over the hydraulic fluid. A further problem is that the large opening will allow dust and debris to fall into the fluid.
