Abstract: A pump is disclosed. The pump may have a housing connectable to a transmission of a machine adjacent a front end of the pump. The pump may also have a flange attached to the housing adjacent a rear end of the pump. The flange may have a longitudinal axis extending along a length of the flange, and a transverse axis extending along a width of the flange. The flange may also have a first mounting hole configured to connect an auxiliary pump to the flange. Further, the flange may have a second mounting hole configured to connect a bracket to the flange. The first mounting hole may be positioned on a first axis inclined at an acute angle relative to the longitudinal axis of the flange.
