About HSI...

Hydraulic Specialists, Inc. was established in 1979 with over 200 years of combined hydraulic experience and is proudly celebrating its 32nd year of business.  We are centrally located in Oklahoma City with a 50,000 sf. repair and warehouse facility.  Hydraulic Specialists, Inc. (HSI) is a remanufacturer of hydraulic components such as pumps, motors, valves, and presses.  We remanufacture OEM (Original Equipment Manufacture) lines such as Oilgear, Denison, Rexroth, and Vickers just to name a few.  We specialize in units the OEM's deem OBSOLETE.

HSI prides itself in being a remanufacturer rather than a repair company.  Why have hydraulic pumps or motors remanufactured?  A remanufactured product is better because of the detailed process that is used to refurbish a unit.  Unlike a repair, remanufacturing requires complete disassembly of the unit and inspection of each part for wear and possible failure.  Each part that fails to pass our stringent inspection process is replaced with a new remanufactured part that meets or exceeds the original manufacturer's specification.  HSI can now warrant the unit with confidence knowing that every effort has been made to ensure a quality unit has been produced.  As you can tell there is a difference.  The difference is detail.

HSI provides many benefits to our customers such as:

• 24/7 Emergency Service
• 24 hour "Hot Shot" door to door delivery service
• All units are tested on one of six test stands to meet OEM specs
• HSI offers a 26 month "Double Pumpers Dozen" warranty
• Outright unit, Remanufactured unit or Exchange unit
• Standard repair, Rush "Hot" repair, or Expedited repair
• "Credit Pool" program
• "Exchange Bank" program
• Quarterly Specials
• Discount Terms

These services allow us to accommodate all the needs of our customers.

We are able to give our customers another option rather than calling the OEM's as well.  Average OEM's have minimum lead times of 20 weeks for an outright unit and minimum of 6 weeks for repair units (depending on make and model).  At HSI, with our years of experience in the industry and our independent facilities, we can offer your client a lead-time of 5-7 days.   Because of our large completed inventory we may have the requested outright or exchange unit in our exchange bank which makes for an immediately delivery and minimizes down time and costs associated.
