Parker Hannifin J501 Hydraulic Pump Motor with Reducer

Parker Hannifin J501 hydraulic pump motor with a HECO 5.2:1 reducer and a 2.250" J501 tapered shaft is a compact hydraulic drive assembly designed for industrial power units and machinery that require a motor-driven hydraulic pump with integrated gearing. The HECO reducer provides a 5.2:1 gear ratio, which lowers output speed while increasing torque to meet demanding hydraulic loading without over-stressing the drive motor. The 2.250" J501 tapered shaft specifies the shaft interface, supporting compatible couplings and drive trains in Parker-compatible systems. This configuration is suitable for applications where consistent torque, predictable speed control, and reliable hydraulic actuation are needed, such as hydraulic power units, material handling equipment, and other machinery that depend on a robust Parker-driven hydraulic drive. The assembly consolidates a pump and reduction stage in a single package, simplifying installation in compatible hydraulic circuits and enabling straightforward integration with standard Parker components and ancillary drive hardware.
