Chemoil Advance Technology supplies Magnetic Coupling Seal-Less Progressive Cavity Pumps from recognized manufacturers for applications where conventional shaft sealing presents particular challenges. These pumps combine progressive cavity pumping technology with a magnetic coupling arrangement, allowing torque to be transmitted without a conventional dynamic shaft seal crossing the containment boundary.

A progressive cavity pump uses a helical rotor rotating within a stator to create progressing cavities that transport fluid continuously from the suction side to the discharge side. The magnetic coupling transfers rotational drive through the containment system, helping reduce the potential leakage path associated with a conventional rotating shaft seal.
