    The manufacturing technology of the product is world leading, which solves a number of oil extraction problems of the world and is adopted innovative submersible plunger pump to exact oil and linear electric motors to drive, increases the oil recovery efficiency observably. Adopt centralized model of remote monitoring system to reduce the number of the persons during extracting oil, supply the service of new type extracting engineering and operating management to help the customers to achieve the goal of lowering the cost and increasing profits. 

    Technical Characteristics

    1. The product set in the down hole, reduces the efficiency loss of the polish rod of the traditional pumping unit during extracting, and saves power 40% ~ 50%, the efficiency is up to 60% ~ 90%;

    2. the volume of the product is small, self weight is only 1t, the floor space is only 5;

    3. The product adopts frequency control, its ground control system can realize remote control, through adjusting the stroke and stroke times and so on to control the production.;

    4. The inspection cycle of the product is 1~3years, the service life is 10 years, reducing the frequency of tripping operation;

    5. Multi-blades sand scratcher set on the end of the plunger pump can solve sand jam problems.

    6. Clearing and preventing devices can prevent wax effectively and clear wax quickly.
