This submersible pump is hermetically sealed
The self-regulating submersible pump MPCTAN (photo) prevents the seal from coming into contact with the product due to its vertical design. The hermetically sealed pump also features a sophisticated safety concept: the impeller back vanes guarantee a complete hydrodynamic seal. Gas barriers (sealing gas) protect the bearing unit against the penetration of product vapors. Bearing and sealing units run without product contact. The dry-running magnetic coupling has no contact with the pumped liquid or its gases. Possible faults in the bearing, seals or separating can are reliably tracked by the sealing gas monitoring system. The MPCTAN submersible pump is thus approved for the highest hazard zone 0 (ATEX). The proven pump now has an immersion length of up to 5.5 m for high-temperature applications, such as in molten salt. — Paul Bungartz GmbH & Co. KG, Düsseldorf, Germany
