3gr Three Spindle Screw Pump Conveying Fuel Oil - China

3G Type three-spindle screw pump

Three spindle screw pumps consist of general design type 3G, marine usage pump 3GC and three screw pumps of special design.

Three spindle screw pump is a positive displacement rotary pump.

Inside the pump casing, as the flanks of teeth of drive screw and idler screws are engaged and the screws are also matched with the three inset holes, several sealed moving chambers are thereby formed in between the pump inlet and outlet end.

These closed chambers will take the medium inside to move from the inlet end axially and let flow pressurized progressively, to have a continuous, constant, axial flow pressured liquids.

Three spindle screw pumps are suitable for pumping various kinds of non-corrosive oil without contents of solid grains and liquids similar to lubricating oils, the viscosity of mediums to be conveyed range from 1.2 to 1000 E (3.0 to 760 CST), liquid with a higher viscosity could also be pumped after heating up (lowering down the viscosity).

Flow range: 0.2 to 590m3/h, the maximum working pressure: 100bar, The highest temperature: 150 degree Celsius

The pump is widely used to Convey fuel oil, lubricating oil, hydraulic oil, cutting oil, cooling oil, coolant, tar, etc.

1 - Simple construction: The pump has quite a few construction forms.

General for small flow range 0.2 to 6.5m3/h, pump casing and insert is made in one part.

Mechanical seal is used as the pump shaft seal.

2 - Pumps of middle and big flow range has a separate insert to be fixed inside the pump casing.

Big pumps are mostly of a double-suction design for horizontal installation.

For different medium pumped, mechanical seals or packing seals could be supplied.

For marine application pumps, installation forms could be horizontal or vertical, with marine AC and DC drivers.

3 - Long life time: As the drive screw is driven by motor and there is no mechanical contact between the drive screw and idler screws, the idler screw are hydraulically driven by the pressured liquids, between the drive screw and idler screw, screws set and insert, an oil film is formed, so the mechanical friction is minimized and a long life is ensured.

4 - The medium to be pumped is in a manner of constant axial flow movement, so the pressure pulsation is almost eliminated, meanwhile the noise is lowered, and as the moving parts have a very little inertia, the starting torque and vibration is very little.

5 - Pump have a very high suction capability.

6 - In order to ensure the safe working of pump, motor, piping system, pumps for a capacity higher than middle flow range are all equipped with safety valves.

When working pressure is exceeding the setting pressure of valves, pressured oil will return to suction chamber.
