3G Marine Three Screw Pump




Applications:


1. 3G three screw pump high pressure oil pump is a kind of positive displacement rotary pump with the properly meshing in pump block.

2. 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.

3. 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.

4. Widely used in oil and gas field, shipbuilding, petrochemical industry, thermal power plant, etc.


Feature

1. Medium is delivered in axial direction continuously without agitation and pulsation.

2. Small vibration and low noise .
3. High pressure and high efficiency .
4. Simple structure, easy disassembly and assembly .
5. Small volume and light weight.
6. Slight wear and long life of the pump.

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

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