This product is designed with advanced 20 series hydraulic transmission technology, developed by the U.S. Department. It features a variable piston pump with a swash plate structure that allows for efficient control of fluid flow, direction, and power in closed-loop hydrostatic drive systems. The pump acts as a charge pump with variable displacement, while the motor is a fixed-displacement motor integrated with a valve block. Control options include manual (MDC), hydraulic (HDC), and electric (EDC) systems, ensuring precise regulation of oil flow.
The pump's displacement can be adjusted based on the angle of the swash plate, allowing for smooth transitions from zero to maximum output. The flow is directly proportional to the spindle speed and displacement. This makes it ideal for use in concrete delivery trucks and other heavy-duty equipment. The PV20 series offers a wide speed range, reliability, and ease of operation.
Key features of the PV20 Series variable piston pump include:
1. High-quality manufacturing with user-friendly operation.
2. Tapered roller bearings on the shaft allow for better resistance to axial forces.
3. Additional pumps can be connected in series for enhanced performance.
4. Mechanical control ensures accurate positioning of the swash plate.
5. When the control lever is released, the swash plate returns to neutral, stopping the flow.
6. Excellent sealing ensures no leakage even under high-temperature conditions.
7. Compatible with servo valves and remote control systems.
8. Easy maintenance due to the removable plunger design.
