Grundfos NB 50-160/175 AAF2KESBQQEHW3 Centrifugal Pump 1.5 kW 3x380-420V DN65/50 PN16 PK25/103

Grundfos NB 50-160/175 AAF2KESBQQEHW3

Normally-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 1092-1. 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 lantern, 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 asynchronous motor.
