Product Description
The VP Series (Variable Displacement Vane Pumps) from Green Hydraulic are designed for high-efficiency hydraulic performance, offering precise control over flow and pressure by automatically adjusting output according to system load. These pumps are recognized for their energy-saving features and low noise operation, making them ideal for industrial automation, machine tools, and mobile machinery. Built to withstand demanding conditions, the VP Series ensures reliable, efficient performance across a wide range of applications.
High Efficiency and Energy Saving: The flow rate automatically decreases as pressure increases, reducing power loss and heat generation caused by excess oil flowing back to the tank via the relief valve.
Low Noise: Thanks to the structural characteristics of the vane pump, its operating noise is quieter than gear pumps, typically between 60-70 dB.
Compact Structure: The pump body is small and usually integrates pressure and flow regulating valves, eliminating the need for complex external control circuits.
Fast Response: Pressure compensation reacts quickly, making it suitable for machinery with frequent operating cycles.
1. Significant Energy Efficiency
On-Demand Oil Supply: It automatically adjusts the flow rate based on system pressure. When the system reaches the set pressure (e.g., during pressure holding), the flow rate automatically decreases to near zero, preventing excess oil from generating heat through the relief valve, thus significantly reducing energy consumption.
Low Heat Generation: Due to reduced overflow losses, the hydraulic oil temperature rises more slowly, extending the service life of the oil and seals, sometimes even eliminating the need for a cooling system.
2. Compact and Integrated Design
Built-in Control Valves: VP pumps typically come with built-in pressure and flow control bolts. This means you don't need to install complex pressure control valves in the piping, simplifying hydraulic system design and saving space.
Small Size: Ideal for installation in small machine tools or space-constrained power units.
3. Low Noise & Smooth Operation
Quiet Operation: The structural characteristics of vane pumps make them quieter than gear pumps of the same displacement even under high pressure (typically between 60-70 dB), contributing to a better workshop working environment.
Minor Pressure Pulsation: The output flow is very uniform, resulting in smoother operation of actuators (such as hydraulic cylinders).
