Product Overview
The HPP-VB2V, HPP-VC2V, HPP-VD2V, and HPP-VF2V series are highly representative swashplate-type variable displacement piston pump product lines from JTEKT (formerly TOYOOKI) . These four series are differentiated by displacement, covering a complete range from 8 cm³/rev to 63 cm³/rev—VB2V series at 8 cm³/rev, VC2V series at 14.5 cm³/rev, VD2V series at 31.5 cm³/rev, and VF2V series at 63 cm³/rev. Among these, HPP-VC2V-L14A3-A is a representative model. These pumps are renowned globally for their low noise, high efficiency, and high responsiveness, and are widely used in high-pressure hydraulic systems, construction machinery, marine equipment, and industrial applications.
As a professional hydraulic component manufacturer, we provide 100% interchangeable replacement solutions for the JTEKT HPP series. Every HPP series piston pump undergoes 100% performance testing under simulated actual operating conditions—from displacement accuracy and pressure stability to volumetric efficiency—fully benchmarked against JTEKT original equipment standards.

Key Technical Advantages
1. Ultra-Low Noise Performance Across the Entire Pressure Range
The HPP series features a swashplate-type variable displacement design that maintains excellent low-noise performance across the entire pressure range. For the HPP-VC2V series, 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. The HPP-VD2V series achieves 56 dB(A) at 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 (for HPP-VC2V 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. The HPP-VF2V series achieves total efficiency ≥ 83%.
3. Superior Response Characteristics
For the HPP-VC2V series, the response time from 14 MPa cut-off to 13.5 MPa is only 0.06 seconds; the response time from 13.5 MPa back to 14 MPa is only 0.03 seconds. This exceptionally fast response ensures rapid system adjustment during load changes, meeting the demands of high-dynamic-response applications.
4. Complete Four-Series Displacement Coverage for Flexible Selection
The HPP series offers four displacement options: 8 cm³/rev (VB2V) , 14.5 cm³/rev (VC2V) , 31.5 cm³/rev (VD2V) , and 63 cm³/rev (VF2V) . Each series provides flange mounting (F) and foot mounting (L) options, side board and axial port (-EE) options, A3 (1–7 MPa) and A5 (3–14 MPa) pressure adjustment ranges, and petroleum-based and water-glycol (-G) fluid compatibility options.
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. Port orientation can be flexibly changed for convenient installation and extended service life.

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.
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
Adjustment can be made via the discharge rate adjustment screw. Minimum discharge rate limits per series:
HPP-VB2V: Minimum discharge rate ≥ 4 L/min
HPP-VC2V: Minimum discharge rate ≥ 5 L/min
HPP-VD2V: Minimum discharge rate ≥ 12 L/min
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.
