Grundfos NB 32-200/176 A-F2-A-BQQE End-suction, single-stage centrifugal pump 3 x 380-415V 4 kW PK25/105

• Grundfos NB 32-200/176 AAF2AESBQQEKW1

Norm-suction, 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 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 housing from the piping. The unbalanced rubber bellows seal conforms to DIN EN 12756. The pump is directly connected to a fan-cooled asynchronous motor.
