Canned-motor pumps for high-temperature applications

With leakage-free, durable canned-motor pumps, this company offers a comprehensive pump concept that has several advantages over other pumping technologies in high-temperature applications. The performance range covers fluid temperatures up to 480°C, system pressures up to 120 MPa and power ratings up to 690 kW. For high-temperature applications, the company offers two designs: canned motor pumps with externally cooled motors and canned motor pumps with adequate internally cooled motors (photo). The rotor lining is manufactured using the extrusion process and, as a nickel-based alloy, is an essential part of the highly efficient canned motor. In the flameproof encapsulated version, the canned motor complies with the explosion protection according to E.U. Directive 2014 / 34 / EU. — Hermetic-Pumpen GmbH, Gundelfingen, Germany
