Eaton gear pumps are the most reliable part of most forklifts — simple, few moving parts, and engineered for continuous duty cycles. When they fail, it's usually because of contaminated hydraulic oil or a seal that's been leaking slowly for too long. The fix is straightforward: a properly refurbished Eaton 4623 or 5421 with new gears, bearings, and seals restores full mast lift performance. PumpGrid does this with a written flow test to confirm output before dispatch.

What Gets Replaced in an Eaton Gear Pump Refurbishment
The primary wear component. New gears restore full volumetric efficiency — meaning full flow at rated RPM.
Shaft seal is always replaced — this is the most common external leak point in any gear pump.
Every sealing element in the pump body is renewed. No carry-forward seals.
Bushings and bearings inspected — replaced if showing wear or roughness on rotation.
Port plates (the wear faces that control internal leakage) are inspected and replaced if worn beyond spec.
Actual flow output measured and documented in the test report. If flow is below spec, the pump is reworked.

Gear Pump Refurb: Best Value in Hydraulics
Of all hydraulic pump types, gear pump refurbishment gives you the highest confidence of near-new performance at the lowest cost. The design is simple, the wear points are known, and the fix is reliable.
