Hydraulic Piston Motors

Product Information

The A6VM55 EP2 63W VZB027DPB is a product in the A6VM series of hydraulic piston motors. This series features axial tapered piston rotors with a slant-shaft design for hydrostatic transmission in both start-up and closed circuits. Its wide control range allows it to meet requirements for high speeds and high torque, making it widely used in both mobile and stationary heavy-duty hydraulic systems.

Product Summary

Hydraulic piston motors provide the reliable power needed for agricultural machinery such as harvesters, sprayers, and tractors. Their high torque output and efficient energy conversion help improve machine productivity during critical farming operations. These motors are designed to handle dust, debris, and varying weather conditions while maintaining consistent performance. With easy integration into hydraulic systems and a focus on durability, hydraulic piston motors help agricultural equipment achieve higher efficiency, reduced maintenance, and extended service life.

Product Specification

Product Features

1,The slanted-shaft plunger structure offers high power density, excellent starting characteristics, and low rotational inertia, making it suitable for heavy-duty applications with frequent starts, stops, and reversals.

2, EP2 electro-proportional control provides smooth adjustment and fast response, facilitating integration into PLC/electronic control systems for automated and precise speed and torque control.

3,It can integrate safety and heat dissipation components such as balance valves and flushing valves, simplifying circuit design and improving system reliability and safety.

4, Suitable for both mobile and stationary equipment, it is impact-resistant, high-pressure resistant, has a long service life, and low maintenance costs.

Product Advantages

Hydraulic piston motors offer high power density, delivering substantial torque within a compact design. They feature high volumetric and mechanical efficiency, minimizing energy loss for economical operation. Excellent low-speed stability enables smooth starting and precise speed control. Robust bearings and optimized porting enhance impact resistance and service life. Their high-pressure capability ensures reliable performance in demanding conditions. Multiple variable control options (displacement, pressure, power) provide an ideal foundation for intelligent and energy-saving systems.

Selection and Usage Recommendations:

1, Determine the rated pressure, peak pressure, speed range, and control signal based on actual operating conditions, and match the pump's output flow rate and pipeline diameter.

2, Strictly control oil cleanliness and temperature (recommended 20–80℃), and regularly maintain the filter element and oil to prevent wear and efficiency degradation.

3, If an integrated balance valve/flushing valve is required, confirm the interface and valve core specifications to ensure safety and heat dissipation requirements.
