HPP-VC2V-F14A3-A TOYOOKI Piston Pump 14.5cc 35 MPa 3000 rpm

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

• Fluid cleanliness requirement: ISO 4406 16/13 (β₅ ≥ 200).

• Regularly monitor fluid cleanliness to prevent contaminants from accelerating piston and cylinder wear.

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.
