The magnetic coupled safe to run dry pump type MPatan accomplishes the explosion protection merely by its design. No level- or temperature monitoring is needed, not even a safeguard for dry running. In the event of a rare disturbance in an ex-zone, the pump will not be a source of ignition.
MPatan is suited for the use in zone-0 vessels. Extreme applications are also possible, like submersion depths of up to 5 m and fluid temperatures up to 200 °C. Rare disturbances such as failures of bearings or seals will not develop as sources of ignition. In the event of a disturbance, the change in barrier-gas flow will be a perfect indicator for the malfunction. If the gas flow tolerances are exceeded, the pump is turned of.
