Eaton built their hydraulic pump reputation on simplicity. The 4623, 5421, and 72400 gear pump series have fewer moving parts than axial piston pumps, tolerate somewhat less-than-perfect hydraulic fluid conditions, and are straightforward to maintain and refurbish.
That simplicity is exactly why refurbished Eaton pumps are such a smart buy. A gear pump refurbishment involves replacing the gear set, bearings, and all seals — the result is essentially a new pump in the original housing. The refurbishment cost is low, the parts are readily available, and the performance is fully restored.
For forklift operators, tipper truck fleet managers, and agricultural equipment owners, a refurbished Eaton gear pump from PumpGrid delivers the performance they need at 40-60% less than a new unit — with a written test report and 3-month warranty backing the quality claim.
Why Gear Pump Refurbishment Gives You Near-New Performance
Unlike axial piston pumps where wear occurs across multiple precision components, gear pump wear is concentrated on the gear teeth, bearing bores, and port plates. Replace these components — which we do as standard — and you have a pump that performs identically to a new unit. Eaton's simple design makes this one of the most reliable refurbishment outcomes in the hydraulic pump world.

Our Eaton Quality Guarantee
Gear Set Replaced as Standard
In every Eaton gear pump refurbishment, the gear set (drive and idler gears) are inspected and replaced if showing wear. This is the primary wear component in a gear pump — replacing it restores pump efficiency to original specification.
New Bearings and Port Plates
Eaton gear pump bearings and port plates (which control internal leakage) are replaced in every refurbishment. This directly restores volumetric efficiency — meaning full flow at rated pressure, confirmed in the test report.
Flow Rate Verified at Rated RPM
Eaton gear pump performance is measured by flow output (LPM) at rated RPM. We test and document actual flow rate — if it doesn't match rated specification, the pump is reworked before dispatch.
3-Month Warranty
Minimum 3-month warranty on all refurbished Eaton pumps. For forklift and tipper fleet operators ordering multiple units, extended warranty options and volume pricing are available — ask at the quote stage.
