Product Description

Product Feature

1.Universal type, double structure, hasd casting and welding two types, it can be widely used in petrochemical, chemical and shipbuilding industries to delivery various viscosity liquid and liquid contain gas.
2.Good self-priming and suction performance, small NPSH value
3.Wide transportation range
4.Transport gas and liquid
5.Small pulse of flow and pressure and stable transportation
6.Not sensitive to the medium and impurity

The advantage of the twin screw pump

1.Transperting the liquid smoothly without any disturbing and pulsation,no impulse, with less vibration and low noise.
2.It has strong self-suction performance, when multi-phase mixed transporting, the gas content can not over80%, and the sand content can not over 500g/m⊃3;
3.Outboard bearing structure which adopt independenlty lubricate, so all kinds of non-lubricative medium can be transported.
4.It adopts synchronous gear driving, between the two rotors there is no touch at all,even though idling for short term is no problem.
5.The pump body has heatinh jacket, so it can transport all kinds of clean or low viscosity or high vicosity medium. Which contain the particulate solids.(the diameter of the particulate is usually less than0.120.2m.
6.If selecting the material correctly, some corrsive medium can be transported.
7.Double-suction structure, and there is no axial force on the rotor.
8.The shaft ends adopt mechanical seal or corrugated pipe mechanical seal it has the characteristic of long-life, less leak wide scope of application.

Preformance Range:
1.The highest pressure 4.0Mpa
2.Capacity rangel1~1000m⊃3;/h
3.Temperarue range-20-120ºC
4.The viscosity of the medium 1-3000mm⊃2;/s when lower the speed of the rotation it can be up to10⊃3;mm⊃2;/s
   The viscosity of the medium will largely influence the twin screw pump, the nominal discharge if the pump means the discharge under the certain viscosity condition, in order to ensure the pump to work oil the high efficiency working condition, when the test is not enough, we suggest to select the speed the rotation according to the following viscosity.
   The viscosity of the medium cst speed r/min
                            <400 1500
                          400~1200 1000
                        1200~3600 750
When the viscosity of the medium is higher, the customer should contact with the manufacture for the speed of rotation and motor power.
