Grundfos NBE 32-125.1/110 AAF2AESBQQEGWB Centrifugal pump 3x380-500V IE5 1.1 kW PK25/104

Grundfos NBE 32-125.1/110 AAF2AESBQQEGWB

Normal-priming, single-stage centrifugal pump according to ISO 5199 with dimensions and rated performance according to EN 733 (10 bar). The pump is equipped with PN 16 flanges. The dimensions comply with EN 1092-2. The pump has an axial suction port and a radial discharge port, as well as a horizontally arranged shaft. The back pull-out design allows for removal of the motor, motor stool, cover, and impeller without disconnecting the pump casing from the piping. The unbalanced rubber bellows seal complies with DIN EN 12756. The pump is directly connected to a fan-cooled permanent magnet synchronous motor. For speed control, the motor has an inverter and PI controller, which are housed in the motor's terminal box. The electronic speed control enables continuous adjustment of the motor speed and thus the pump performance to the current demand.
