CENTRIFUGAL PUMP GRUNDFOS NK80-200/222A2F2AE-SBAQE

Normally, the dimensions of a single-stage, end-suction centrifugal pump comply with standard ISO 5199, and the rated capacity conforms to standard EN 733. The dimensions of PN 16 flanges are in accordance with standard EN 1092-2. The pump has an axial suction opening, a radial discharge opening, and a horizontal shaft. The coupling, bearing housing, and impeller can be withdrawn from the rear without disturbing the pump casing or piping. The unbalanced rubber seal ring complies with standard DIN EN 12756. The pump and motor are mounted on a common base plate.
