HPR
Xeriwell or Others
The Linde HPR series hydraulic pumps are high-performance, self-regulating pumps designed for open-circuit systems. They offer exceptional durability, precision, and adaptability, making them suitable for various industrial and mobile applications.
Features:
1）High Pressure Capacity: The HPR series operates at pressures up to 420 bar, with peak pressure capability reaching 500 bar, ensuring reliable performance under demanding conditions.
2）Energy-Efficient Operation: Featuring "flow on demand" control, the pump minimizes energy consumption by adjusting hydraulic output to meet system requirements.
3）Dynamic Performance: With excellent suction capabilities and responsive control mechanisms, the HPR pumps deliver stable and precise hydraulic flow across a wide range of operating speeds.
4）Noise Reduction Technology: The integration of SPU (Silencer Pulsation Unit) reduces pressure pulsations by up to 70%, ensuring quieter operation in sensitive environments.
5）Modular and Versatile Design: The HPR series supports various configurations, including tandem and multiple pump setups, with compatibility for SAE high-pressure ports and a range of mounting flanges.
The Linde HPR series hydraulic pumps are ideal for industries requiring efficient and robust hydraulic solutions, such as construction, material handling, and energy production.
