These pumps mix the air with the water to create a fluid that has pumping properties similar to water. The air is then removed by the pump leaving only water that is moved through the pump like centrifugal pumps.
You need to remember that there must be water in the casing for these residential pumps to operate. Self-priming means that your pump can turn the mixture of water and air into a fluid that can be pumped. The pump won’t prime if there is only air present in it.
The self-priming pump can overcome the problem of air binding due to the in-built water reservoir that is not present in centrifugal pumps. The air is removed by the recirculation of water through this water reservoir. After the evacuation of all air, water is forced towards the impeller through the suction line and pumping starts.
