    Key Applications in Construction Machinery

    The Vicks VQ series high-pressure vane pump is a top choice for reliability and performance in the tough world of construction and engineering equipment. Built to work well even in the toughest conditions, these pumps provide steady power and control that modern, high-performance machines need.
    The single pump configuration of the VQ Series is ideal for applications that requiring a close and efficient hydraulic power source. In construction machinery, single pumps are widely used in systems where simple and cost-effectiveness are prioritized. For example, in small to medium-sized excavators or compact loaders, the single VQ pump delivers consistent flow and pressure to power functions such as boom movement, steering, and implement control. Its high volumetric efficiency (up to 95%) ensures minimal energy loss, while robust construction materials withstand harsh operating conditions, including contamination and temperature variations. The single pump’s ability to operate at pressures up to 310 bar makes it suitable for high-load tasks, enhancing machine productivity and reliability.
    Knowing that construction projects require minimal downtime, the VQ series has a special cartridge design. This lets you quickly and easily replace the pump’s core part in the field without taking the whole pump off the machine. This simple design makes service faster and lowers inventory costs, helping keep equipment running and work moving smoothly.

    Technical Features of Vickers VQ-Series Vane Pumps

    1.To adopt balanced hydraulic for the struction of intra-vane and ten-Vane design, higher pressure, top to 21 MPa.
    2.To adopt floating structure for 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, it improved the seizure resistance. and so that the life of pump will be longer
