    HVG MARINE PUMP 0017: 3G Marine Three Screw Pump

    Applications:

    • 3G three screw pump high pressure oil pump is a kind of positive displacement rotary pump with the properly meshing in pump block.
    • It could be used to transfer non-corrosive oil or lubricated liquid that similar to oil, and the double jacket one could pump heavy oil, bitumn, resin.
    • Pump is with double jacket casing which can be heated by hot steam, thermal oil, etc to reduce the viscosity of fluids with easy solidification.
    • Widely used in oil and gas field, shipbuilding, petrochemical industry, thermal power plant, etc.

    Feature

    • Medium is delivered in axial direction continuously without agitation and pulsation.
    • Small vibration and low noise .
    • High pressure and high efficiency .
    • Simple structure, easy disassembly and assembly .
    • Small volume and light weight.
    • Slight wear and long life of the pump.

    Material: The driving and driven screw 16MnCrS5,40Cr,45,38CrMoALA　Pump casing:　HT200,QT450-10,ZCuSn10Pl,ZG270-500.

    According to the application modes three screw pump is divided into five series:
