Multi grade Screw Pump is the crew pump with several lobes. The oil suction efficiency is improved by a large margin. Except multi lobe screw pumps, our company also provides single screw pumps and double progressive cavity pumps. Comparing these three different types of screw pumps, screw pump with several lobes has the largest torque.
GLB single screw Oil Pump is a new type of mechanical extracting equipment, not only suitable for the low viscosity crude oil production, but the high viscosity oil, high pour point oil, high wax content oil, high sand content and gas content oil exploitation. It is effectively complementary to conventional pump with the character of less investment, efficient oil production, low energy consumption, convenient for installation, operation and maintenance, It will become widely used mechanical extracting equipment. Through the deep research in the key component rubber stator`s performance of the anti-wear and swelling resistant, the problem of the rubber wear-resistant has been basically solved.
The driving part on ground runs smoothly with little noise.
Feature A: The adoption of a special structured mechanical sealing device ensure the safe and reliable sealing performance. On the polish rod, there is no bending stress points, need no maintenance and adjustment, which ensure safe and stable production of crude oil without leak and protects the well site environment.
Features B: The product adopts a special anti-inversion structure, which realizes the reliable braking( brake torque reaches more than 4000N.m) and the release of free to ensure the safe and convenient operation in oil wells.
Features C: Diesel power driving is designed for the wells without power source.
Features D: The electrical device is controlled by the variable frequency the realize the stepless speed change, and the excellent overload protection with obvious energy saving effect. The driving motor`s power is from 11kw to 22kw.
