Abstract

Abstract Pump is a device used to move a liquid from one place to another by increasing the pressure of the liquid. The increase in fluid pressure is used to overcome the flow resistance. The flow barriers can be in the form of pressure differences, height differences or frictional resistance. In principle, the pump converts the mechanical energy of the motor into the energy of the fluid flow. The energy received by the fluid will be used to increase the pressure and overcome the resistance contained in the channel through which it is passed. The swimming pool pump at the Sendang Sari Batang hotel is a type of centrifugal pump. Centrifugal pump as one type of pump that is often found in industry works on the principle of impeller rotation as a fluid moving element which is driven by a prime mover. The liquid inside will rotate due to the thrust of the blades and cause a centrifugal force which causes the liquid that flows from the center of the impeller and exits through the channel between the blades and leaves the impeller at high speed. When carrying out ground practice activities at the Sendang Sari hotel, the author found a problem / constraint on the centrifugal pump. The problem is the occurrence of cavitation which results in the formation of bubbles and the occurrence of friction between the impeller and the casing. The results of this study are to carry out maintenance and repair of pumps, to prevent cavitation by taking preventive measures, and to reinstall loose nuts and bolts. Seeing the above incident, it is advisable to do regular centrifugal pump maintenance to minimize the occurrence of further damage in order to support the smooth operation of the pump. Keywords : Pump, Impeller, Maintenance
