VP5F Series Low Noise Variable Vane Pumps for Injection Molding Machines

Product Overview: The VP5F Series variable volume vane pump is the definitive power choice for modern injection molding machinery prioritizing energy efficiency and silent operation. As a Pressure Compensated variable pump, it instantaneously adjusts flow output to match the specific demands of the injection process—such as clamping, injection, and pressure holding. This range features core models optimized for injection machines, including VP5F-A4-50S, VP5F-A5-50S, and the enhanced VP5FA-5-50. Utilizing a precision-engineered regulation mechanism, the VP5F series automatically reduces flow once preset pressure is reached, drastically lowering energy consumption and heat generation.

Key Technical Advantages:

• Ultimate Silent Operation (Low Noise): Featuring advanced noise-reduction architecture and high-precision ground components, decibel levels remain exceptionally low even during the pressure-holding phase, improving the workshop environment.

• Significant Energy Savings & Low Heat: Automatic pressure compensation eliminates unnecessary overflow losses during idle periods, extending the service life of hydraulic oil and seals while reducing cooling requirements.

• Fast & Precise Response: Provides millisecond-level flow switching response, ensuring smooth transitions between machine cycles and improving product molding accuracy.

• High Reliability Design: Specifically reinforced for the high-frequency reciprocating cycles of injection machines, with the 50S series offering superior wear resistance.

• Target Applications: Horizontal/Vertical injection molding machines, CNC cutting tools, shoe-making presses, hydraulic brick machines, and automated production lines.
