Explanation: VictrexÒ PEEK Sealless Magnetic Pump Containment Shells
Molded for strength and tested for safety
Containment and movement of hazardous media in CPI applications is of paramount importance
to the safety of people and the environment. Sealless magnetic pumps are designed to transport hazardous liquids while minimizing the risk of catastrophic leakage. Part of the success of this design is to eliminate the use of all dynamic seals where the risk of potential leakage paths is highest. But how are the rotating interfaces sealed? One of the keys to the success of this design is to impart rotational movement to the pump by way of electromagnetism through a statically sealed containment shell. However, to make the design work effectively, the Shell has critical requirements that have to be overcome. The Shell must be transparent to electromagnetic waves, strong enough to withstand internal pressures of up to 500psi, and chemically resistant enough to withstand a broad range of aggressive chemical media conventionally contained using exotic metallic alloys such as HastelloyÒ . The material of choice…..VictrexÒ PEEK (polyaryletherketone, polyetheretherketone).
