3GC25*4 3GC Self priming triple screw pump for oils transfer Description

3GC Self priming triple screw pump for fuel oil transfer

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

The 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.  The 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 liquid.

 Triple 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 could also be pumped after heating up (lowering down the viscosity)

The flow range : 0.2 to 590m3/h,  Max. working pressure:100bar,   the highest temperature of pumped liquids: 150 degree Celsius.

1.       Simple in 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.

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

2.       Long life time: As the drive screw is driven by motor and there is no mechanical contact between the drive screw and the idler screws, the idler screws are hydraulically driven by the pressured liquid, between the drive screw and idler screw, screws set and insert, an oil film is formed, so the mechanical frication is minimized and a longer life is ensured.

3.       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 little inertia, the starting torque and vibration is very little.

4.       Pump have a very high suction capability.

5.       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. Pressured oil will circulate back to suction chamber.
