Pump spare parts are accessories consisting of several components that form a single unit and have a specific function for the pump. Here are some pump parts you need to know:1. ImpellerThe impeller or vane of the water pump is a pump spare part that is used to encourage the flow of water. Usually the impeller can wear out within a certain time depending on the constraints it experiences. Damage to this component will be faster if the transferred water contains solid substances such as sand because it will scratch the impeller. There are several kinds of impeller materials ranging from plastic, cast iron, brass to stainless steel.2. Diffuser
The diffuser is a spare part of the housing or impeller housing to help increase the pressure generated by the water pump. Over time the diffuser can also become porous or wear out due to friction with the impeller but this occurs over a long period of time. The diffuser needs to be checked periodically so that the water pump pressure remains stable.3.Mechanical SealMechanical Seal serves to prevent water leakage at the border between the pump and the motor. Generally, the mechanical seal material is carbon or ceramic. Due to continuous friction during pump operation, this part will wear out or thin and must be replaced immediately before it leaks. Leaks in the mechanical seal can cause water to enter the motor and can cause the motor to burn out.4. BearingsBearing is a pump spare part that functions to hold the position of the rotor shaft against the motor so that there is no friction during rotation. This component will wear out in a certain period of time with a marked noise or rough when the pump is running. If the rough bearing continues to be used, the water pump performance will decrease and in the worst case the bearing will jam or stumble and can cause the motor to burn out.5. CapacitorsCapacitor is a pump spare part that functions as a starter or helps when the motor will start to rotate. This part is only found on single phase (220 V) motors. The value of the capacitor will decrease slowly over time. Sometimes the capacitor can explode, usually due to an electrical disturbance. Damage to the capacitor causes the pump to not spin.
