Medium-sized Excavator
PVH is an axial piston variable pump , suitable for medium to high-pressure hydraulic systems in industrial machinery, construction machinery and other fields. Its displacement is 73.7cm³/rev, the rated pressure is 250 bar (25MPa), and the peak pressure can reach 280 bar (28MPa). The pump adopts a swashplate structure and can dynamically adjust the flow according to system requirements through various control methods such as pressure compensation and load sensing, with significant energy-saving effects.
Advantages
Energy Efficiency: Flow is adjusted on demand, saving about 15% - 20% energy compared to fixed displacement pumps.
High-Pressure Stability: Can work stably under high pressure to meet the power needs of heavy equipment.
Low-Noise Operation: Optimized design reduces pressure pulsation, with low operating noise, ≤70dB(A).
Durability and Reliability: Critical components are made of high-strength materials, resistant to wear and pollution, with a long service life.
Strong Adaptability: Multiple control modes facilitate integration with different hydraulic systems.
Compact Structure: Small size and light weight, with low installation space requirements.
