When using a self priming centrifugal pump for the first time, it is necessary to check whether the pump body is fixed properly to prevent loosening when the motor is turned on. This leads to leakage of the interface.
Before connecting the pump body power supply, check the integrity of the power cord and plug. To prevent electric shock accidents, corresponding protective measures such as short-circuit circuit breakers must be installed.
3. The working voltage range of the pump body should be around the rated voltage and should not exceed too much. Otherwise, it will shorten the service life of the motor and even burn it out.
4. Although self priming centrifugal pumps have strong self priming ability, they still need to be filled with water when first used, but in the future, there is no need to inject water.
When using a self priming centrifugal pump, it is important to keep the motor dry to prevent corrosion or short circuits due to humidity. And attention should be paid to the decrease in water level. The bottom valve of the self priming centrifugal pump should not be exposed to the water surface, otherwise it will cause the self priming pump to spin and damage it.
