Key Technical Advantages
1. Ultra-Low Noise Performance Across the Entire Pressure Range
The HPP-VF2V series features a swashplate-type variable displacement design that maintains excellent low-noise performance across the entire pressure range. At 14 MPa rated pressure and 1,200 min⁻¹ speed, noise measured at 1 meter from the pump is only 56 dB(A) at cut-off and 60 dB(A) before cut-off. At 7 MPa operating conditions, noise is 59 dB(A) at cut-off and 64 dB(A) before cut-off. This noise level is among the best in its class among large piston pumps, making it ideal for noise-sensitive workshops and industrial environments.
2. Exceptional Efficiency for Significant Energy Savings
The pump achieves 95% volumetric efficiency and 85% total efficiency (at 13.5 MPa, 1,800 min⁻¹); under standard test conditions (6.5 MPa, 1,800 min⁻¹), total efficiency reaches 83%. This ultra-high efficiency means minimal power loss and reduced fluid temperature rise, allowing the use of smaller reservoirs for system miniaturization and cost reduction. The pressure-compensated variable mechanism automatically adjusts output flow and pressure according to load changes, eliminating the need for separate relief valves and unloading valves, significantly reducing unnecessary power consumption.
3. Superior Response Characteristics
The HPP-VF2V series features high responsiveness—the response time from 14 MPa cut-off to 13.5 MPa is only 0.07 seconds; the response time from 13.5 MPa back to 14 MPa is only 0.06 seconds. This exceptionally fast response ensures rapid system adjustment during load changes, meeting the demands of high-dynamic-response applications.
4. Duplex Pump Combination Capability — Space Saving
The HPP-VF2V series can be combined with the HPP-VC2V series as an HPP-VCF2V duplex variable piston pump, with both pumps driven by a single motor. The oil discharged from the two pumps can be supplied to separate circuits for different actuators or combined to drive a single actuator. This design saves installation space and reduces system integration complexity.
5. High Reliability with Long Service Life
Manufactured from high-strength cast iron with precision machining processes, the mature swashplate-type variable design ensures proven reliability. Bearings are designed for long service life, maintaining stable performance across the entire pressure range. Port orientation can be flexibly changed for convenient installation. Standardized structural design ensures strong parts interchangeability for convenient maintenance and replacement.

Expert Maintenance Tips
1. Verify Rotation Direction
Viewed from the shaft end, rotation is clockwise (right-hand rotation) . Always verify alignment with the drive motor’s rotation before installation. Reverse operation is strictly prohibited.
2. First Start-up and Priming
Fill the pump body with working oil through the filler port before starting the pump. When connecting the drain line, start from the highest drain port. Never start the pump dry—this will cause severe wear or seizure of pistons and slippers.
3. Drain Back Pressure and Suction Pressure Control
Drain allowable back pressure should be set below 0.03 MPa. Suction pressure should be set within -0.02 MPa. When a check valve is installed on the pump discharge side, use a check valve with 0.005 MPa cracking pressure.
4. Fluid Cleanliness Management
Piston pumps are extremely sensitive to fluid cleanliness. Install 10–20 μm line filters. Maintain fluid cleanliness to NAS Class 7 or higher. Standard models are designed for petroleum-based hydraulic fluids; for water-glycol fluids, select the dedicated -G suffix model. Optimum operating oil temperature range is 20–60°C.
5. Pressure Adjustment Precautions
The HPP-VF2V series pressure adjustment range is 1.4–7 MPa. Do not exceed the maximum adjustment range to avoid damaging internal control components.
6. Speed Range Control
7. Regular Inspection and Maintenance
Regularly inspect the system filter element condition. Regularly monitor the pump for abnormal operating noise—if abnormal noise or system pressure drop is detected, shut down immediately for inspection. The HPP-VF2V series features standardized structural design with strong parts interchangeability for convenient maintenance and replacement.
