Impeller Nut incl. Gasket ND.1/ND.2

The impeller nut with integrated gasket serves to firmly secure the impeller axially on the motor shaft of the ND.1 and ND.2 pumps. A properly tightened nut prevents axial displacement of the impeller and deformation of the shaft seal. The gasket under the nut prevents water from seeping along the shaft. Replacement of the nut and gasket is recommended whenever the impeller is removed, to ensure proper function after reassembly. The original part is made of a material resistant to corrosion and the chemicals in pool water. Tightening must be carried out to the correct torque according to the manufacturer’s service manual.
