VQ Series Double Pump

The VQ Series double pump incorporates advanced features designed to enhance performance and reliability in hydraulic applications. Utilizing a balanced hydraulic structure with intra-vane and ten-vane designs, the pump can achieve impressive pressure levels of up to 21 MPa, making it suitable for high-demand environments. Its innovative floating side plate automatically compensates for end-face clearance, ensuring that high volumetric efficiency is maintained even under significant pressure. This feature minimizes the risk of energy loss and optimizes operational performance. The side plate is crafted from dual-metal materials, significantly improving seizure resistance. This enhancement not only protects against wear but also extends the pump's operational lifespan, reducing maintenance needs and costs. Collectively, these features position the VQ Series double pump as a robust and efficient solution for a wide range of hydraulic systems, from manufacturing to automotive applications, ensuring durability and consistent performance in challenging conditions.

Features:
1. To adopt balanced hydraulic for the construction of Intra-vane and ten-Vane designs, higher Pressure, top to 21 MPa.
2. To adopt a floating structure for the side plate, it will do a compensation for end-face clearance by automatic, so that even the pump under high pressure it can maintain a high volumetric efficiency.
3. The side plate is made of dual- metal material, which improves seizure resistance. and so that the life of the pump will be longer.
