Cavity Pump Working Principle


The progressive cavity pump consist of gerneral design type 3G,marine uasge pump 3GC and three screw pumps of special design.The three spindle screw pump is a postive displacement rotary pump.Inside the pump casing,as the flankof teeth of drive screw and idler moving chambers are thereby formed in between the pump inlet and outlet end.These losed chambers will take the medium inside to move from the inlet end axially and let flow oressurized progressively ,to have a continuous,constant,axial flow pressured liquid. The three spindle screw pumps are suitable for pumping various kinds of non-crrosive oil without content of solid grains and liquids similar to lubricationg oils,The viscosity of mediums to be convey range from 1.2 to 100*E(3.0 to 760cst),liquid with a higher viscosity could also be pumped after heating up(lowering down the viscosity).The flow range is 0.2-590m^3/h,and the maximum working pressure is 100 bar,The higtest temperature is 150°C


Cavity Pump Features


1.Simple in construction:The three screw pump has quite a few construction forms.Geeral for small flow range 0.2-0.6m^3/h,pump casing and insert is made in one part.Mechanical sea is used as the pump shaft seal.The of middle and big flow range have a seperate insert to be fix in side the pump casing.Big pumps are mostly of double-suction-different medium to be pumped mechanical seals or packing seals could be supplied For marine application pumps,installation forms could be horizontal and vertical,with marine AC and dc drivers.

2.Long life time:As the driver screw is driven by motor and there is no mechanical contact between the drive screw set and insert an oil minimized and alonger 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 very 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,When working pressure is exceeding the setting pressure of valves.,pressure oil will circulate back to suction chamber.

In order to quote price qucikly,we need custmer tell us the fllowing questions:

1.How much Capacity do you need?

2.How much Discharge Pressure do you need?

3.What liquid do you want the pump to deal with? The approximate temperature of that liquid? And how much is the viscocity?

4.The working time of the pump? You want it work discontinuously or continuously?


With your answers our engineer can choose a best pump for you!
