VPKCC-F3030-A3A3-01 KCL Double Vane Pump 30 cc/rev 250 bar

Product Overview

The VPKC Series and VPKCC Series, manufactured by KCL (Kai Jia, a renowned Taiwanese hydraulic brand), are low-pressure variable displacement vane pump product lines widely used in various industrial hydraulic systems requiring low noise and high efficiency. Featuring variable vane pump design, the series provides automatic flow adjustment and compensation function at set pressure, offering lower power loss and reduced heat generation compared to fixed displacement vane pumps—making it an energy-efficient, high-performance vane pump.

The VPKC Series comprises single variable vane pumps available in F8, F12, F15, F20, F23, F26, F30, F40, and other specifications. The VPKCC Series comprises double variable vane pumps integrating two pump sections into one housing driven by a single shaft, simultaneously powering two independent hydraulic circuits. Double pump model naming follows “VPKCC-F(section 1 displacement)(section 2 displacement)-A(pressure code)A(pressure code)-01”—for example, VPKCC-F3030 indicates 30 cc/rev per section.

Our products are manufactured to be 100% interchangeable with KCL original specifications—a true “drop-in” replacement solution. Every unit undergoes 100% full-load and flow-matching testing under simulated operating conditions before shipment, ensuring volumetric efficiency, flow rate, and noise performance meet or exceed original specifications at rated pressure.

Key Technical Advantages

1. Variable Energy-Saving Design – Significantly Reduced Power Loss
The VPKC/VPKCC Series features a variable vane pump design that automatically adjusts flow and provides compensation at set pressure. Compared to fixed displacement vane pumps, this series automatically regulates output flow based on actual system demand, resulting in lower power loss, reduced heat generation, and superior energy efficiency.

2. Double Pump Design – Single Power Source, Dual-Circuit Independent Control
The VPKCC Series integrates two pump sections into one housing driven by a single shaft. This design allows a single power source to simultaneously serve two independent hydraulic circuits or provide greater total flow through combined delivery. The double pump configuration offers more compact installation and lower cost.

3. High Pressure Capability and Wide Speed Range
The VPKCC Series double pumps achieve maximum operating pressures up to 250 bar and maximum speeds up to 3000 r/min. High-pressure capability allows the use of smaller actuators and lines, while the wide speed range enables the series to adapt to diverse applications—from low-speed high-torque to high-speed light-load operations.

4. Flexible Pressure Options – Low-Pressure Energy-Saving and High-Pressure Types
The VPKC Series offers both low-pressure energy-saving types (e.g., F40-A4, 70 bar) and high-pressure types (VPKCC Series, 250 bar). Users can flexibly select based on actual system pressure requirements for optimal energy efficiency matching.

5. Quick Response and High Efficiency
KCL VPKC/VPKCC Series vane pumps feature quick responsiveness and high efficiency. The variable mechanism responds rapidly, quickly tracking system load changes to ensure stable and precise system operation.

6. 100% Drop-In Interchangeability – Zero Retrofit Cost
Manufactured to exact KCL original specifications—mounting dimensions, port locations, and shaft configurations are identical to the original. No piping modifications or installation adapters are required for direct replacement.

Expert Maintenance Tips

1. Model Identification and Selection

• VPKC Series: Single variable vane pump. In model VPKC-F40-A4-01, F40 = 40 cc/rev displacement, A4 = pressure code.

• VPKCC Series: Double variable vane pump. In model VPKCC-F3030-A3A3-01, F3030 = 30 cc/rev per section, A3A3 = pressure code A3 for both sections.

• Pressure Code Meaning: A1/A2/A3/A4 correspond to different pressure setting ranges—select based on actual system operating pressure.

2. Installation Precautions

• Verify pump rotation direction matches system requirements—standard is clockwise (viewed from shaft end); counter-clockwise versions require special ordering.

• VPKC/VPKCC Series uses flange mounting—confirm mounting flange dimensions match the system.

• Suction piping should be as short as possible, minimizing unnecessary restrictions.

• The pump housing must not bear piping loads; suction and discharge lines must have independent supports.

3. Pre-Startup Checklist

• Verify oil level in the reservoir is adequate and fluid type is correct (ISO VG32, VG46, or VG68 anti-wear hydraulic oil recommended).

• Confirm all piping connections are secure with no leakage.

• Prime the pump by filling the housing with oil before first startup to prevent dry running.

• For variable pumps, set the pressure adjustment screw to minimum pressure before startup, then gradually adjust to required pressure after normal operation begins.

4. Fluid Management

• High-quality anti-wear hydraulic oil is recommended; maintain fluid cleanliness at NAS 9 or higher—contamination is the leading cause of premature vane pump failure.

• VPKC/VPKCC Series are low-pressure variable pumps with relatively flexible viscosity requirements, but regular fluid condition checks are still necessary.

• Regularly check oil temperature to ensure it does not exceed 60°C.

5. Scheduled Maintenance

• Replace hydraulic oil and filters every 2000 operating hours or annually.

• VPKC/VPKCC Series feature cartridge-type construction—cartridges can be replaced independently.

• Pressure settings should be periodically verified to ensure they match system requirements.

• If flow drops or pressure becomes unstable, first inspect cartridge wear and variable mechanism condition.
