Hydraulic components require working parts that are flawless and free of defects. To assure maximum performance and customer satisfaction each cylinder, pump, motor and control valve is disassembled and inspected. After components are visually checked, micrometers and calipers are used to determine proper tolerance and abnormal wear. The results of the inspection are noted on our work order and are thoroughly reviewed with our customers.

With the customer’s approval, HMS then completes the repairs needed using quality replacement parts and experienced personnel. The units are then tested, painted and stamped with a reference number.

HMS is committed to earning your respect, your confidence and your business. We take responsibility as your hydraulic component-reconditioning supplier. We strive to be your most valuable hydraulic resource.
