Oil Stator Tube

An oil stator tube is a core stationary component in a Progressive Cavity Pump or a Positive Displacement Motor. It is a tubular structure with a helical internal cavity, typically lined with an elastic material (such as rubber) or designed with an all-metal construction. It works in conjunction with the internal rotor to achieve fluid transportation or power transmission through helical motion. Stator tubes play a crucial role in the oil and gas industry, ensuring stable operation of equipment in high-temperature, high-pressure, and corrosive environments.

Oil stator tubes are mainly made of alloy steel shells and rubber liners (or all-metal), and are wear-resistant, corrosion-resistant, and high-temperature resistant. They are widely used in oil extraction, directional drilling, and mud pump auxiliary systems.
