Product Overview
The HPP-VC2V-F14A3-A, HPP-VC2V-F14A5-A, and HPP-VD2V series variable displacement piston pumps originate from Japan’s TOYOOKI Kogyo – now part of the JTEKT Group. TOYOOKI is a renowned Japanese manufacturer of hydraulic components, and its HPP Series swash plate variable displacement piston pumps are recognized for low noise, high efficiency, and high responsiveness.
The HPP-VC2V Series represents TOYOOKI’s 3rd generation intelligent electronically-controlled variable piston pumps, designed for precision flow control and energy-saving hydraulic systems. The series features swash plate variable displacement construction with electro-proportional pressure-flow composite control and CANopen communication capability.
The HPP-VD2V Series offers a larger displacement option within the same technology platform.
Key Interchangeability Advantage: Our HPP series variable piston pumps are manufactured to strict Japanese TOYOOKI original design specifications, ensuring 100% direct interchangeability with original units. All mounting interfaces (SAE flange), shaft configurations, and port positions are identical to the original product – no modifications required. Every pump undergoes 100% factory performance testing under simulated operating conditions (covering rated pressure, peak pressure, and full speed range performance curves), guaranteeing plug-and-play reliability with zero performance deviation.

Key Technical Advantages
1. Swash Plate Variable Construction with Electro-Proportional Control for Precision Flow Regulation
The HPP-VC2V Series features swash plate variable piston pump construction with electro-proportional pressure-flow composite control delivering stepless variable displacement with resolution down to 0.1 mL/rev. CANopen communication enables seamless integration into modern intelligent hydraulic systems. Full displacement switching response time ≤ 45 ms meets demanding dynamic response requirements.
2. Ultra-Low Noise and High Efficiency Operation
The HPP Series variable piston pumps are renowned for low noise, high efficiency, and high responsiveness. The HPP-VD2V achieves noise levels as low as 56 dB(A) at 14 MPa (at cut-off); the HPP-VC2V-F14A3-A delivers just 74 dB(A) at 35 MPa rated operation. Volumetric efficiency reaches 95% with overall efficiency of approximately 85% – significantly reducing energy consumption and operating costs.
3. Digital Twin Interface and Intelligent Maintenance Functions
The HPP-VC2V Series features built-in condition monitoring sensors (vibration/temperature/pressure) with predictive maintenance capabilities:
Bearing remaining life estimation (based on vibration trend analysis)
Seal wear warning (via leak flow monitoring)
16 fault self-diagnosis codes (including overload/overtemperature/communication errors)
4. Adaptive Control Algorithm for Automatic Energy Optimization
Built-in adaptive control algorithms automatically learn load characteristics and optimize energy consumption. Combined with stepless variable technology and high-precision control (repeat accuracy ±0.8% FS), the pump delivers on-demand flow under variable load conditions, significantly reducing system energy consumption.

Expert Maintenance Tips
1. Model Confirmation and Selection
HPP-VC2V-F14A3-A: Displacement 14.5 cc/rev, pressure range 1–7 MPa, industrial anti-corrosion coating
HPP-VC2V-F14A5-A: Displacement 14.5 cc/rev, pressure range 3–14 MPa
HPP-VD2V: Displacement 31.5 cc/rev, A3 (1–7 MPa) or A5 (3–14 MPa)
Verify system operating pressure, flow requirements, and control type during selection.
2. Pre-Installation Checks
Confirm pump mounting type is flange mounting (F type) compatible with system interface.
Verify electrical configuration: 24VDC ±10% power supply (ripple < 100mVp-p), use CAT6 shielded twisted pair (termination resistor 120Ω).
Inlet pressure: -0.03 MPa (absolute pressure) .
Never use hammer-driven installation – always use proper tools.
3. First Start-Up & System Configuration
Prime the pump housing with clean hydraulic oil before first start-up; ensure suction line is fully filled – never run dry.
Required accessories: TOYOOKI HMC-3000 series controller and pilot filter (β₁₀ ≥ 1000).
Install accumulator (capacity ≥ 10L) to absorb pulsation.
Maintain operating temperature within 30–90℃.
4. Filtration & Fluid Cleanliness
5. Operating Monitoring
Rated operating pressure must not exceed 35 MPa (HPP-VC2V-F14A3-A); peak pressure must not exceed 42 MPa (≤ 1 minute).
Utilize built-in condition monitoring to regularly check vibration, temperature, and pressure data.
If abnormal noise or pressure fluctuation occurs, first check suction lines for leakage or blockage.
Regularly check torque on pump and piping connection bolts to prevent loosening from vibration.
