Gear Pump Repair

Gear Pump Repair

Gear pump repair for hydraulic and process pumps — external and internal gear designs, wear plates, bushings, seals and gear sets.

Gear Pump Repair — what it covers

Gear pump repair covers both external gear pumps (two meshing spur or helical gears in a close-tolerance housing) and internal gear designs. Loss of flow, cavitation noise, shaft seal leakage and pressure fade almost always trace to the same short list: worn gear faces, scored wear plates, worn bushings or bores, and failed shaft seals.

Rebuild scope typically includes disassembly and cleaning, dimensional check of gear OD and face width against print, wear plate and bushing replacement, housing bore inspection and restoration, new shaft seals and gaskets, reassembly to running clearance, then a flow and pressure test on the bench before shipping.

Hydraulic gear pumps on mobile and press equipment, process gear pumps on asphalt, polymer, adhesive and chemical duty, and lube-oil gear pumps on turbines and compressors are all routine work. Where a pump is inexpensive and in stock, we say replace it — you get the repair number and the replacement number side by side.

Gear Pump Repair questions

Is a gear pump worth repairing?
It depends on size and availability. Small hydraulic gear pumps are often cheap enough new that replacement wins. Larger process and lube-oil gear pumps, and any obsolete or long-lead unit, are routinely worth rebuilding at a fraction of new cost. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
What causes gear pump failure?
Most commonly contamination and lubrication problems: dirty fluid abrades gear faces and wear plates, low viscosity or aeration causes cavitation damage, and misalignment or overhung load kills shaft seals and bushings early. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
How long does gear pump repair take?
Typically 5–10 business days, faster than most gearbox work because the parts count is lower. Emergency turnaround is available. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
