Industrial Pump Repair Service in Knoxville

We repair and rebuild all major types of industrial hydraulic and hydrostatic pumps, including axial piston pumps, bent axis motors, closed circuit pumps, gear pumps, and variable displacement units. Our services cover equipment from hundreds of manufacturers including Sundstrand, Eaton, Sauer-Danfoss, Rexroth, Kawasaki, Komatsu, Parker, Vickers, and many others. We handle pumps used in excavators, bulldozers, mining equipment, manufacturing machinery, agricultural equipment, material handling systems, and specialized industrial applications. If you have an unusual or obsolete pump, contact us—our extensive manufacturer database and parts network allow us to service units other shops cannot.

Turnaround time depends on the extent of damage and parts availability, but most standard rebuilds ship within 3 days of receiving your unit. For critical downtime situations, we offer exchange programs that can get you back online immediately—you receive a remanufactured pump while we rebuild your original core. Rush service is available for emergency situations. Complex repairs requiring custom machining or hard-to-source parts may take 1-2 weeks. We provide status updates throughout the repair process and can expedite shipping to minimize your total downtime. Our mobile service units can also perform certain repairs on-site at your Knoxville facility.

Yes, every pump we rebuild comes with a comprehensive 1-year warranty covering parts and workmanship. This warranty reflects our confidence in the quality of our OEM-spec rebuilds and the expertise of our factory-trained technicians. We also offer a full money-back guarantee on many services—if you're not completely satisfied with the performance of your rebuilt pump, we'll make it right. All repairs are tested and calibrated to manufacturer specifications before shipment, ensuring your equipment performs exactly as it should. Warranty coverage includes both the hydraulic components we rebuild and any replacement parts we install during the repair process.

Absolutely. One of our core strengths is sourcing parts for difficult-to-locate, obsolete, and discontinued hydraulic components. Our extensive manufacturer database and supplier network give us access to seal kits, overhaul kits, control components, charge pumps, internal components, and specialty parts that other shops simply cannot obtain. We maintain inventory for many common wear items and can often fabricate custom components when original parts are no longer available. Whether you're running current equipment or maintaining legacy systems that are 20+ years old, we have the resources and expertise to keep your industrial pumps operating reliably.

We service industrial hydraulic systems from virtually all major equipment manufacturers, including Caterpillar, Komatsu, John Deere, Hitachi, Case, Volvo, Liebherr, Doosan, Terex, Hyundai, Kobelco, XCMG, Sany, and hundreds of others. Our pump repair expertise covers brands like Sundstrand, Eaton, Sauer-Danfoss, Danfoss, Rexroth, Kawasaki, Parker, Vickers, Denison, Linde, and many more. We also service specialized equipment used in mining, railroad, sawmill, manufacturing, agricultural, and material handling applications. If you're unsure whether we can service your specific equipment, contact us with your pump model information—our comprehensive reference database likely includes your system.

Yes, we operate mobile service units equipped to perform many hydraulic repairs directly at your job site or facility. This on-site capability is particularly valuable when equipment cannot be easily transported or when downtime costs make it impractical to remove and ship components. Our mobile warehouses carry commonly needed parts and tools, and our factory-trained technicians can diagnose problems, perform repairs, and conduct system testing without disrupting your entire operation. For more complex rebuilds requiring specialized equipment, we can remove the pump for service at our facility and provide a loaner or exchange unit to keep your equipment operational during the repair.

Repair costs vary significantly based on pump type, extent of damage, required parts, and service level needed. A basic seal kit replacement might cost a few hundred dollars, while a complete rebuild of a large excavator main pump could run several thousand. We provide free quotes after evaluating your specific pump and determining exactly what repairs are needed. Our pricing is transparent and competitive, and we'll explain all options before beginning work. Exchange programs can offer cost savings compared to emergency rebuilds, and our parts supply service helps you budget for preventive maintenance. Contact us at 800-361-0028 or sales@htsrepair.com for a detailed quote on your specific repair needs.

To provide an accurate quote, we need the pump manufacturer, model number, and serial number if available. Photos of the pump nameplate and overall unit are extremely helpful. Describe the symptoms or failure mode you're experiencing—such as loss of pressure, unusual noise, leaking, overheating, or complete failure. Let us know what equipment the pump is installed in (excavator, bulldozer, manufacturing machine, etc.) and its application. If you have the pump removed already, information about visible damage or wear is useful. The more details you provide, the more accurate our quote will be. You can call us at 800-361-0028 or email sales@htsrepair.com with this information to receive your free quote.
