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
refer to Series 45 Axial Piston Open Circuit Pumps Technical Information TIM 520L0519.
