Parameter Specification of Vickers Hydraulic Vane Pump V10-1P7P-1A20

1. Model Interpretation

• V10: Series identifier, indicating the V10 series fixed displacement hydraulic vane pump, featuring a pressure-balanced and modular design for low noise and long service life, widely applied in small industrial hydraulic equipment and small injection molding machines, with a displacement range of 3.3-28 cm³/r (0.2-1.71 in³/r).
• 1P: Shaft configuration, representing 1-keyed straight shaft with standard keyway design for stable power transmission, consistent with the standard shaft configuration of the V10 series.
• 1P7P: Displacement code, corresponding to a geometric displacement of 23.1 ml/r (1.41 in³/r), which is derived from the V10 series displacement coding rule, within the series displacement range, and determines the pump’s flow capacity.
• 1A20: Mounting and port configuration, indicating a standard mounting mode with optimized port position, compatible with small industrial hydraulic system installations, featuring 4 mounting holes for stable fixation, and adaptable to low to medium pressure working scenarios.

3. Structural and Performance Features

• Pressure-balanced modular design: Diametrically opposed inlet and outlet pressure chambers balance pressure-induced radial loads, reducing bearing wear and extending service life, which is suitable for low to medium pressure working conditions up to 138 bar, consistent with the V10 series performance standards and applicable to small equipment scenarios.
• 12-vane system: Equipped with an intra-vane design to reduce flow pulsations and operating noise, ensuring stable fluid output even with the small to medium displacement of 23.1 ml/r, adapting to the series’ low-noise design requirement and small injection molding machine working needs.
• Self-compensating vane design: Vanes automatically adjust to compensate for wear and clearances, maintaining consistent volumetric efficiency throughout the service life and adapting to long-term continuous operation, which is a core feature of the V10 series.
• Versatile installation: Inlet and outlet ports can be rotated in 90-degree increments, and the 1A20 configuration with 4 mounting holes provides stable and flexible installation options, compatible with various small industrial hydraulic equipment and small injection molding machines.
• Robust durability: The optimized structural design ensures excellent performance at low speeds (minimum 600 rpm) and medium pressures without damage, suitable for rugged small industrial application scenarios that require small to medium displacement and stable output, within the V10 series’ application scope.

4. Application and Installation Notes

4.1 Application Scope

4.2 Installation Precautions

• Ensure the drive shaft is aligned with the power source shaft to avoid radial loading and shaft end thrust, which is particularly important for the pump with small to medium displacement to prevent structural damage.
• If the pump is mounted above the fluid level, fill the pump with system fluid through the outlet port before start-up to ensure internal lubrication and avoid dry friction during initial operation.
• Maintain fluid cleanliness to meet or exceed ISO cleanliness code 17/14, and replace filter elements according to the supplier’s instructions to protect the pump’s internal components and ensure stable operation.
• Bleed entrapped air from the outlet circuit until a steady output flow is observed during initial start-up, which can effectively avoid cavitation and ensure the pump’s performance.
