Product Description
Sauer-Danfoss SPV Series Closed Circuit Axial Piston Variable Pump
Product Overview: The Sauer-Danfoss SPV series (based on the legendary Series 20 design) is one of the most reliable Closed Circuit hydrostatic solutions in the industry. Covering a vast displacement range from the compact SPV18 to the heavy-duty SPV74, these pumps are tailor-made for mobile machinery drive systems. Renowned for their simple swashplate architecture and exceptional durability, the SPV series ensures smooth operation under high-frequency direction changes and variable speed conditions, serving as the power core for rollers, mixers, and combine harvesters worldwide.
Key Technical Advantages:
Integrated Closed-Loop Solution: The SPV pumps feature an internal charge pump and built-in high-pressure relief valves, simplifying circuit plumbing, reducing system heat, and enhancing response times.
Extensive Specification Range: From the SPV18/SPV20 for light equipment to the SPV22/SPV23 for medium-duty drives and the SPV64/SPV74 for heavy machinery, this series offers comprehensive power matching.
Precise Control Modulation: Supports manual servo, hydraulic servo, and electro-hydraulic proportional control options, ensuring seamless power delivery during startup, incline climbing, and braking cycles.
Superior Service Life: Utilizing high-strength cast iron housings and hardened piston components, the SPV series maintains stable performance for thousands of hours, even in dusty and high-vibration construction environments.
