Commercial Hydraulics Inc Pumps, Motors & Cross-References

Commercial Hydraulics Inc is a hydraulic equipment repair, refurbishment, and service shop in Knoxville, Tennessee, founded in the early 1980s and still active. The company rebuilds and remanufactures hydraulic pumps, motors, cylinders, and valves and supplies replacement components and power units, rather than manufacturing its own pump or motor lines. Northern Hydraulics lists Commercial Hydraulics Inc as a manufacturer-directory entry and does not stock its products. Instead, we cross-reference equivalent and replacement parts so you can keep a machine running when the original source is a repair shop rather than an OEM.

Important: Commercial Hydraulics Inc (Knoxville, TN) is a separate business from Commercial Intertech Corporation, the pump manufacturer founded in 1920 and acquired by Parker Hannifin in 2000. If you are looking for Commercial Intertech 300 Series, PX Series, or Stealth-technology pumps now sold under Parker-Commercial Intertech branding, those are a different line. Send us the casting numbers and we will route you to the correct equivalent.

Commercial Hydraulics Inc Product Lines & Series

Commercial Hydraulics Inc is a rebuild and remanufacture operation, not a series-based component manufacturer, so its work has no published catalog or interchange table. What passes through the shop falls into a handful of categories:

• Rebuilt and remanufactured hydraulic pumps — gear, piston, and vane units returned to service.
• Rebuilt and remanufactured hydraulic motors — drive and wheel motors restored to working spec.
• Rebuilt and remanufactured hydraulic cylinders — reseal, rebore, and rod replacement.
• Hydraulic valves — directional, relief, and control valves serviced and supplied.
• Power units — assembled and reconditioned hydraulic power packs.

Because none of these carry a clean OEM line number, the practical question is rarely “which Commercial Hydraulics part number” and almost always “which current production part does this match.” That is where cross-referencing takes over.

Cross-Referencing Commercial Hydraulics Inc Parts

Parts you received through Commercial Hydraulics Inc often carry no clean OEM catalog number and no published interchange table. That is exactly where cross-referencing earns its keep. Send us the pump, motor, cylinder, or valve you need matched, along with any tag data, bore and stroke dimensions, displacement, port configuration, or photos of the casting, and we will identify a current equivalent or replacement component from the manufacturers we supply.

This is the core of what we do for thin and obsolete-source brands: identify the function and specification, then map it to a part you can actually buy today. When a rebuilt or remanufactured unit reaches end of life, an equivalent from a current production line is usually faster and more reliable than chasing another rebuild. Request a cross-reference quote with your part details and we will return matched options.
