How do I choose the correct excavator hydraulic gear pump?
Short Answer
Choose the correct excavator hydraulic gear pump by matching pump nameplate, shaft type, rotation direction, mounting flange, port size, displacement, pressure rating, and the function it supplies. JIAJUE confirms these details before quoting because a gear pump may serve pilot, steering, charge, cooling, or auxiliary circuits, and the wrong rotation or shaft can fail immediately.
What To Check
- Send pump tag photos, shaft photos, mounting flange, inlet and outlet ports, hose layout, and machine serial number.
- Confirm clockwise or counterclockwise rotation, spline or keyed shaft, port thread, displacement, and whether it is a single or tandem gear pump.
- Check oil contamination, broken coupling, suction restriction, relief setting, and whether the pump failed after another hydraulic repair.
