The newly developed HCN/HCNF range of canned motor pumps was designed for the most demanding areas of application. The HCN range is designed for aggressive, inflammable, toxic and highly volatile liquids, solvents or other substances. The HCNF range is used for liquid gases, such as ammonia, Freon, propane and carbon dioxide. The most recent development is a single-stage standardized chemical canned motor pump (photo, p. 32I-4) in accordance with EN 22858/ISO 2858. The area of application for liquids covers a temperature range from –120 to 120°C. The pump performance lies between 6 and 41 kW, with a maximum flowrate of 230 m3/h and a maximum head of 140 m. One special design feature is an integrated monitoring system for the rotation direction, which is firmly molded in the terminal box. A thermistor secured in the winding guarantees efficient protection of the motor. — Hermetic-Pumpen GmbH, Grundelfingen, Germany
