Key Technical Advantages

1. Ultra-Low Noise Performance Across the Entire Pressure Range

The HPP-VB2V 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 53 dB(A) at cut-off and 58 dB(A) before cut-off. This noise level is among the best in its class, making it ideal for noise-sensitive environments.

2. Exceptional Efficiency for Significant Energy Savings

The pump achieves 95% volumetric efficiency and 90% total efficiency (at 13.5 MPa, 1,800 min⁻¹). 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.

3. Superior Response Characteristics

The HPP-VB2V series features high responsiveness, integrating multiple control methods into a complete control system with comprehensive advantages including energy savings, compact size, and low cost. The built-in pressure compensation mechanism simplifies hydraulic system design by eliminating complex additional control valve groups.

4. Compact Lightweight Design — Space Saving

The HPP-VB2V series features compact lightweight design with total weight of only approximately 16 kg. The compact structure makes it particularly suitable for applications with limited installation space. Port orientation can be flexibly changed for convenient installation.

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. Minimal power loss further enhances overall system reliability.

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. 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.

5. Pressure Adjustment Precautions

• A3 suffix models: Pressure adjustment range 1–7 MPa

• A5 suffix models: Pressure adjustment range 3–14 MPa

• Do not exceed the maximum adjustment range for each model, as this may damage internal control components

6. Discharge Rate Adjustment

For the HPP-VB2V series, the minimum discharge rate should be set at 4 L/min or more, independent of speed.

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.
