Full Text	This invention relates to the improvements incorporated in a submersible monoblock pump. In this IMPROVISED SUBMERSIBLE MONOBLOCK PUMP', the wmdings and bearings are oil lubricated, contrary to the conventional Submersible Monoblock Pumps, which are lubricated by water. Oil is the most suitable lubricating agent and accordingly the lubricating properties of transformer oil has been made use of in this 'IMPROVISED SUBMERSIBLE MONOBLOCK PUMP'. Accordingly, the pump has been suitably amended to incorporate the oil lubricating system, through a duct emanating from the transformer for lubricating the enameled copper wire, ball bearings and the aluminum die casting rotor. Transformer oil absorbs heat that is created inside the motor thereby increasing the life of the motor. In the conventional pumps, water must be filled in the motors in order to lubricate the windings of the bearings. This would normally result in carry over of water to the other parts of the system in spite of seals being used, which would result in rapid rust formation, corrosion and deterioration of the various accessories early. However, in this IMPROVISED SUBMERSIBLE MONOBLOCK PUMP', because of the oil lubrication system, these draw backs have been overcome. Further, as a matter of abundant safety, to ensure - 2 - that silts do not enter the motor, oil seals have been provided at the ^propriate places. Enameled copper wire is used in this IMPROVISED SUBMERSIBLE MONOBLOCK PUMP in place of the PVC insulated winding wires, which are used in the conventional pumps. In the conventional pumps, gunmetal bushes are used which wear out fast. In order to overcome this drawback, ball bearings are used which have a better life and this has also resulted in total elimination of the sound pollution. Further, the use of the ball bearings in place of gunmetal bushes aids in proper torque maintenance, which ensures free run of the motor. This results in good performance of the IMPROVISED SUBMERSIBLE MONOBLOCK PUMPS as the discharge is good and the performance is higher than the conventional ones. Discharge has been found to be up to 20,000 liters per hour In this IMPROVISED SUBMERSIBLE MONOBLOCK PUMP, there is no necessity for any bushes, as the design of the pump is such. Wherein, the use of bushes is a must in the conventional submersible monoblock pumps. Use of bushes means frequent wear and tear, which consequents in frequent replacement of bushes. This anomaly has been overcome in this IMPROVISED SUBMERSIBLE MONOBLOCK PUMP. In case of Conventional Submersible Pumps, the rotor is made of copper and consequently the rotor is very heavy, because of which it becomes difficult handling at the time of overhaul. However, in this IMPROVISED SUBMERSIBLE MONOBLOCK PUMP, the rotor is die cast out of aluminum, which is of lighter weight, consequent to which overhauling of the pump is easier now. Further, this has resulted in considerable weight reduction of the entire submersible monoblock pump unit, which goes a long way in easy installation of the pump. The use of enamel winding in place of PVC insulated wires in this IMPROVISED SUBMERSIBLE MONOBLOCK PUMP is ideal for low voltage and can also withstand voltage fluctuations, consequent to which the savings on power is to the tune of 50%.
