Hydraulic handheld tools need fluid in order to operate, and STANLEY® hydraulic power units are the market-leading solution. STANLEY®'s HP12 hydraulic power unit is built to provide consistent, high-quality flow and pressure for professional use with Type 2 and Type 3 hydraulic tools. Type 1 and Type 2 hydraulic equipment can benefit from our HP8 hydraulic power unit, which is built for continuous, rigorous use in industrial and commercial environments in municipal applications. Our HP28 features a revolutionary design capable of operating two tools at 8 gpm simultaneously, increasing productivity and versatility like never before. Our other power unit offerings include the HV18 Hydraverter, an alternative way to run hydraulic tools. The Hydraverter utilizes existing hydraulics on equipment such as a backhoe, excavator, or skid steer loader to operate hydraulic tools. STANLEY® is your go-to source for the hydraulic power you need.
