Progressive Cavity Pump
GLB screw pump family is a new mechanical pump series, this pump is powered by surface driving system, and the energy is transfered to downhole screw pump evenly by fortified sucking rod. GLB screw pump family presents the common characteristics as simple structure, small volume, light weight, easy maintenance, energy saving and low price, and such pump is available to various liquid as high viscous oil, high wax content oil, sand content oil and gas content oil. GLB screw pump family is belonged to the new generation of oil production equipments. table 1 specification of GLB single screw pump
