Ground power single screw pump is a new type of oil production equipment; Because of its less move parts, no valves and complex flow passage, it has characters of less water loss, continuous inhalation and discharge, not easy to block by sand and air. This type of pump can transport various kinds of mediums, including highly viscous crude, sandy crude and high water content mix fluid.
The pump consists of single screw pump and ground-driving device. The ground-driving device drives down hole screw pump through sucker rods to pumping the underground crude.
Performance & Features
• High production efficiency, low energy consumption, volume efficiency over 80%.
• Precise manufacturing with dimension tolerance ≤±0.02mm
• Large displacement (5-400m3/d),high lift(1000-2000m).
• High adaptability for high viscosity, high sand and gas content well.
• Rotor is treated with micro hole hard chrome plating and stator is anticorrosion treated. High corrosive resistance.
• Hollow rotor is easy to hot-wash well, clean wax, inject chemical agent and test well condition .
