Product Description
HPV55 & HPV135 Series Closed Circuit Variable Displacement Pump
Product Overview: The HPV series (including HPV55-02 and HPV135-02R) is an axial piston variable pump specifically engineered for high-pressure closed-circuit hydraulic systems. Serving as the power core for travel drives, winch controls, and heavy-duty swing mechanisms, this series is renowned for its superior power density and exceptional control dynamics. Whether in mid-sized excavators or massive construction machinery, the HPV series provides bi-directional, infinitely variable flow control, ensuring smooth and precise machine operation.
Key Technical Advantages:
High-Performance Closed Circuit Design: Optimized for bi-directional flow. Models like the HPV135-02R support frequent reversals under high-pressure conditions and feature integrated high-pressure relief valves and charge control logic, simplifying system plumbing.
Precision Variable Control (-02 Series): Utilizing advanced swashplate mechanisms, this series supports hydraulic or electronic proportional control. The HPV55-02R responds instantaneously to load demands, achieving millisecond-level displacement adjustments.
Durability for Extreme Cycles: Engineered for heavy-duty travel and continuous duty cycles. Reinforced bearing supports and precision-ground piston groups maintain high volumetric efficiency even at peak pressures of 420 Bar.
Serial-Specific Compatibility: Strictly adapted to OEM specifications for codes like H2X262A11836 and HYX265G01722, guaranteeing 100% physical compatibility with specific excavator models or mobile undercarriages.
Specific Models & Technical Parameters: This range features core configurations: HPV55-02R (2594), HPV135-02R (0001), and the full HPV55-02 series. Key specifications: Displacements from 55 cm³/rev to 135 cm³/rev; rated operating pressure of 35-42 MPa (350-420 Bar); support for Clockwise (R) rotation; equipped with standard SAE or ISO mounting patterns and specific splined shafts.
