51501-11 Hydraulic Pump
51501-11 Hydraulic Pump
51501-11 “A” Gear Pump — 4.0, CCW
The 51501-11 is an “A” position gear pump identified by the supplier as a 4.0 counterclockwise configuration. Those details matter: displacement class, rotation, side or position, shaft, and porting all influence whether the pump can work safely in the system.
Why This Matters
A gear pump with the wrong rotation can fail to build pressure correctly and may damage the system. Do not infer compatibility from size or mounting alone.
