    Frequently Asked Questions

    What are the primary applications of the VG internal gear pump?

    The VG internal gear pump is widely applied to hydraulic systems in various industries, including plastic machines, shoe machines, die-casting machinery, and forklifts. It is particularly suitable for energy-saving systems driven by servo inverters.

    How does the pump maintain volumetric efficiency at lower speeds?

    The pump adopts an advanced axial and radial pressure compensation design. This configuration ensures that it maintains high volumetric efficiency even when operating at low speeds and with low viscosity fluids.

    What is the maximum working pressure and speed for the VG series?

    The VG series features a high-pressure design with a maximum working pressure of up to 35MPa. It also offers a wide speed range, with the highest operating speed reaching up to 3000r/min.

    Is the VG internal gear pump sensitive to oil contamination?

    No, the VG internal gear pump is designed to be highly tolerant and not sensitive to oil pollution. This robust design contributes significantly to its long service life.

    Can these gear pumps be combined for multi-flow setups?

    Yes, the VG internal gear pumps can be combined arbitrarily to form a double pump configuration, allowing for flexible flow and pressure outputs based on system requirements.
