Hermetically sealed, low-maintenance pumps that are suitable for extreme applications and hazardous liquids are the core competence of HERMETIC-Pumpen GmbH. With its CAMT and CNF series, the canned motor pump specialist provides safe and durable units that offer system operators a number of advantages for the production process of ammonia when compared to conventional centrifugal pumps. While the CNF series with an integrated auxiliary impeller and internal fluid return system is specifically designed for pumping liquefied gases as well as boiling media and condensates, the tandem configuration of the CAMT series offers an effective solution for pumping small quantities at high delivery heads, as is typically the case when pumping liquid ammonia into a storage tank.
