Hydro-Gear PK-3KBQ-GV1B-XXXX 12cc Hydraulic Pump

Restore dependable hydraulic performance with the exact PK-Series build. The Hydro-Gear PK-3KBQ-GV1B-XXXX is listed as a PK-Series variable-displacement hydraulic pump with a supplier-listed displacement of 12 cc.

Displacement alone does not establish fitment. Rotation, shaft, control, ports, mounting, and the complete build code all matter.

Why This Matters

Pumps with similar housings can differ in rotation, shaft, controls, ports, mounting, and internal configuration. The wrong unit can cause erratic operation, overheating, weak performance, or system damage.
