SN Screw Pump FEATURES: (three screw pump or three spindle pump)

SN screw pump is a kind three screw pump or spindle marine pump, for Lube oil transfer, lubrication oil supply, cargo oil pump in marine industry.

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.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 liquid.


The 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 100°E(3.0 to 760 cst) ,liquid with a higher viscosity could also be pumped after heating up (lowering down the viscosity). The flow range is 0.2~590m3/h, and the maximum working pressure is 100 bar, The highest temperature is 150C.

Application: Sub models: SNH, SNF and SNS three screw pump, all similar to Allweiler pump.

In heating techniqzzues as fuel oil and medium with lubricating pvoperties.

In the engineering industry as hydraulic-,and telemotor pumps.

In the chemical and food industry ascargo-,transfer or supply pumps.

In the marine field as transfer-,booster-,fuel oil pumps as well for ship hydraulics.
