Auxiliary mounting pads
Auxiliary mounting pads are available for all radial ported Series 45 pumps. These pads are typically used
for mounting auxiliary hydraulic pumps.
Since the auxiliary pad operates under case pressure, an O-ring must be used to seal the auxiliary pump
mounting flange to the pad. The drive coupling is lubricated by oil from the main pump case. For details
