Oswal Monoblock Pump OMB-54-1PH (5HP) is powered by a totally enclosed fan cooled AC induction motor which is ideal for long hours working. Motor stator is made of low watt loss steel laminations which are assembled under pressure. With the help of well-balanced rotor, there is no vibration and noise while working. Varnish impregnated windings are made up of enameled copper wire which offers best resistance.
