The laminations are non-oriented silicon steel & confirms to IS-648. Volute, Impeller, Adaptor, Stator body, Endshield shall be made of close grained cast iron of high tensile strength and has a very smooth surface finish resulting in low friction losses.
Motor windings shall be vacuum impregnated with synthetic varnish for better moisture resistance.
Superior mechanical shaft seal for longer life and effective sealing against water leakage. The electric rotor is pressure die cast & uses electric grade aluminium. Grease Lubricated anti-friction ball bearings shall be fitted at both ends to withstand radial and axial loads.
They are precisely machined on modern machine tools to give you years of reliable operation.
Better insulating materials are used so that pumpset can with stand high temperature rise.
