Flanged end-suction pumps with an I-MAT VSD unit mounted on the top. The NM Series of centrifugal pumps are close-coupled type pumps that have flanged connections. The electrically-powered motor is connected directly to the pump by means of an extended shaft for motors up to a power rating of 30 kW. Standard motors between 37 and 75 kW have a bracket construction that incorporates a thrust bearing integrated into the structure. The flanges' connections comply with PN 10 and EN 1092-2 standards.
