NKM-GE 50-250/263/A/BAQE/4/4 T Centrifugal pump for pressure systems with MCE55/C DAB.NKM-GE MCE/C

Specified split shaft centrifugal monobloc pumps suitable for a wide range of applications such as: -hot water circulation for heating -cold water circulation for air conditioning -cold water circulation for refrigeration. Highly versatile pumps thanks to the use with MCE/C frequency converter, to ensure optimum pump performance and the ability to adapt automatically to different system requirements while maintaining a constant pressure. Cast iron body to DIN - EN 733 (ex DIN24255), flanges to DIN 2533 and DIN 2532 for DN 200. Cast iron impeller, pump shaft in AISI 304 stainless steel. Mechanical seal: carbon/silicon carbide with EPDM o-rings according to DIN 24960. Asynchronous motor: externally cooled, vented, design B3/B5, 2-pole for NKP-GE and 4-pole for NKM-GE.
