  • GNG series Progressive cavity pump is also called single screw pump. The Progressive cavity pump consists of helical rotor turning inside a helical stator. When the rotor turns inside the stator, the honeycomb progresses spirally along the axis of the pump without changing either shape or volume. This action transfers the material from the pump intake to the pump discharge without degrading the product. So the GNG series Progressive cavity pump is an ideal pump for feeding decanter centrifuges.

    The GNG series pump Progressive cavity pump body and transmission parts are designed according to the maximum load of 6 bar pressure. The pump has many features include: stronger strength, durable, safe and reliable. The flow and head of the pump fully meet the requirements of sludge transportation and dosing. Moreover it fully meet the stable and unmanned long-term operation.

    Features of GNG Centrifuge Feed Pump

    The pump stator rubber of the GNG series Progressive cavity pump is firmly combined with the outer casing. There are no seams, pores or cracks in the working face. The stator is made of SBBPF or other required material. The design normal working life is not less than 10,000 hours under the specified working conditions. The stator feed end is funnel-shaped, which is conducive for full flow of material.

    Depends on different material and application, the pump rotor can be stainless steel or hard alloy material with special treatment to make it anti abrasion as well as corrosion resistant.

    The gear reducer selected for GNG series pump is compact and integrated with the motor. The motor is suitable for 380V/460V or any customized power supply. It is completely suitable for 10-60Hz range regulation.
