Traditional methods of pumping crude oil with gas is being replaced by multiphase pump, a more effective method, compared to traditional methods, multiphase Twin Screw pump does not require separating oil, water and gas from the crude oil, n ot require several pipes for liquids and gas, n ot require compressor and oil transfer pump. Multiphase Twin Screw pump has been developed basing on the ordinary Twin Screw pump, the principle of multiphase Twin screw pump is similar to the ordinary, but its designing and condiguration is special, multiphase Twin Screw pump transfer the multiphase flow of oil, water and gas, Multiphasse Twin Screw pump is the pivotal equipment in the multiphase system. It could reduced pressure of well head, improve the output of crude oil, it not only reduce the coast of base construction, but also implifys the procedure of mining technology, improve the life of oil well, HW multiphase Twin Screw pump can be used in not only oil field on land and sea but also fringe oil field. The max, capacity can reach 2000 m3/h, and the differential pressure 5 MPa, GVF 98%.
