Since 1968, CRS Service, Inc. has manufactured and distributed replacement pumps and hydraulic components, with much of its precision work handled in-house at its Rochester Hills, Michigan facility. The company began making hydraulic vane-pump components in 1972 and expanded that expertise by acquiring the Gresen line in 2003, improving the pumps’ efficiency, noise level and durability. CRS also pairs its manufacturing operation with a large inventory, same-day shipping on stocked orders and fluid-power application consultation and training.
