• to be used in hazardous facilities to handle toxic, combustible and explosive media, including those at high temperatures;
• minimum maintenance required during the entire service life, does not require barrier fluid supply piping;
• excellent anti-cavitaion properties, optional designs include pre-started axial stage (inducer);
• comply with TDFA.062443.300TU;
• comply with the Customs Union Technical Regulations TR TS 004, 010, 012;
• certificates for design and manufacturing nuclear power plant equipment.

The pumps in this series have earned a reputation of compact, no-maintenance units. Reliable design, low noise and vibration levels make them one of the most popular choice for petrochemical pumps. These pumps have the widest range of types and sizes, multiplied by modifications* inherent to petrochemical processes. The original thermobarriers design prevents liquid-cooling of the pump and its systems when handling high-temperature media.
