Traditionally, in magnetically driven pumps and mixers, 5 – 10 percent of the energy is lost as heat due to eddy currents. When using Greene, Tweed’s composite shell, manufactured from our Xycomp® material, pumps require less energy than traditional shells, therefore, reducing costs. The Xycomp shell is used for magnetic couplings in pumps and mixers in hydrocarbon and chemical applications.
The Xycomp shell acts as the sealing element of the magnet coupling. It seals the inner rotor (impeller side) from the outer rotor (motor side), allowing an eddy current-free transmission of the magnetic force. The lack of eddy current enhances torque transmission, increasing efficiency in refineries and protecting the environment.
Made from an advanced thermoplastic composite, reinforced with high strength carbon fiber and molded through our proprietary Techna3™ process, the containment shell is an ideal replacement for materials such as 316SS and Hastelloy®.
Techna3 is a proprietary composite capability for manufacturing complex, contoured composite shapes in a single part, eliminating multiple pieces. Secondary machining is often unnecessary. Techna3 also facilitates the forming of walls thinner than existing plastic or ceramic containment shells or double-walled metallic shells. Thinner walled Xycomp shells can be a benefit in some applications. The calculation shows the difference.
