A pump or fluid-powered motor and a flange may include a pump housing defining an inlet and an outlet and internal pump components arranged within the housing and operably coupled to a drive shaft extending out of an end of the housing and defining a longitudinal axis. A pump flange may be arranged on the end of the housing and comprising a generally rectangular plate having a plurality of bolt holes. The pump flange may also include a pilot projection defining a pilot diameter, a torque pin feature, and a through bore with the drive shaft extending therethrough. The plurality of bolt holes may define a rectangular pattern with an X-spacing a Y-spacing. The torque pin feature may be arranged a distance from the longitudinal axis and on the Y-axis, wherein a ratio of the distance to the pilot diameter ranges from approximately 0.50 to approximately 0.70.

A pump/motor and flange may include a housing with a longitudinal centerline, a drive-level bore and an idler-level bore. The drive-level bore and the idler-level bore may be equally spaced away from the longitudinal centerline. The drive-level bore may be spaced apart from the idler-level bore by a pump/motor gauge distance. The pump/motor may also include a drive shaft having a longitudinal axis parallel to and offset from the longitudinal centerline of the housing. A flange may be provided having a drive shaft opening configured to receive the drive shaft. The flange may also include a first mounting hole spaced downward from the drive shaft opening by a first distance equal to the pump gauge distance plus the offset distance. The flange may also include a second mounting hole spaced upward from the drive shaft opening by a second distance equal to the first distance.

A pump or fluid-powered motor may include a housing defining an inlet and an outlet, internal pump components arranged within the housing and operably coupled to a drive shaft having a mechanical coupling mechanism adapted to engage a corresponding mechanical drive mechanism at a mount location. A flange may be secured to the housing and adapted for securing the pump to the mount location and may include a rectangular plate having a through bore and a substantially cylindrical pilot extending therefrom, defining a first diameter, and including a peripheral groove. The flange may also include a plurality of bolt holes extending through the rectangular plate and arranged on a bolt circle with a second diameter. The second diameter may be approximately 240 mm and a distance from a top pair of the bolt holes to a bottom edge of the rectangular plate may be approximately 200 mm.
