Before checking the important points in a proper maintenance plan, the centrifugal pump’s environment, i.e. in which environment it is operating and how much it is exposed to, should be considered. This will help determine its performance, reliability, and efficiency.
To know the efficiency of the centrifugal pump that is already installed, mechanical, volumetric and hydraulic efficiency must be considered, the latter being the most essential factor in determining the overall efficiency. Among the activities for the correct maintenance of the centrifugal pump are the verification of gaskets and mechanical seals that will prevent leaks. In addition, it is significant to check the correct operation of the motor.
In ideal conditions, centrifugal pumps can operate indefinitely. Under adverse conditions, they often break down. For example, if the fluid being pumped is corrosive or contains abrasives, the pump will require more maintenance than is required under more favourable conditions. However, the life of any pump can be extended by proper maintenance procedures.
