Impeller And Diffuser

The part of impeller and Diffuser in electric Petroleum Submersed Pump is a principal component in the pump, which drives the impeller to make high-speed rotation in certain rev by motor. The impeller makes centrifugal movement to transport liquid to the guide shell whose function is to make energy conversion and convey it to the impeller of subordinate grade. Hierarchical conversion and transmission make each grade of impeller and diffuser generate lift increase and accumulate to lift for the whole pump. The impeller and diffusers manufactured by the Group adopt CAD software design and apply CAM five-shaft processing die, ensuring stability and accuracy in molded lines for impeller and diffuser products. Meanwhile, it supplies three hydraulic performance parameters including lift, flow and efficiency in the product of impeller and diffuser for users so as to design the optimal product. Besides, there are products made from different materials such as ferronickel, nickelic abrasion resistant ferronickel, copper alloy, and stainless steel depending on well conditions for users to select, satisfying demands of users for difference in shaft diameter.

     The Group has become a supermarket for products of impeller and diffuser and petroleum-submersed pump accessories manufactured both at home and abroad.
