KDNE by DAB is a standardized centrifugal single impeller pump with MCE-C variable frequency drive. KDNE with MCE-C is designed for circulation of water for conditioning and heating in commercial building service. Axial suction connector, radial delivery connector. The pump is engineered to allow disassembly of the bearings, impeller and seal without removing the pump body (back pull out design). KDNE can be coupled to a two or four-pole electric motor. Cast iron or bronze impeller depending on the models. The MCE-C variable frequency drive is able to maintain constant or proportional differential pressures thanks to the differential pressure sensor installed, increases efficiency, protects against water hammer, saves energy and thanks to the display allows simple pump configuration. Possibility of remote control thanks to the DConnect service (with DConnect Box supplied separately). DAB make also the KDNE with MCE-P variable frequency drive for pressurization tasks.
