basic information
...When a new pump is first started, it is essential to perform "priming." This means filling the pump with water in advance so that it can create a water flow. So, what happens if you stop a pump that has just started working? The impeller stops, the centrifugal force disappears, the water flow ceases, and the water inside the casing loses its direction and flows back to the suction inlet... As the water inside the casing decreases, the next time you try to operate the pump, it may not be able to create a proper water flow. However, this is a "self-priming" pump, which can retain enough priming water inside the casing for the next operation!!!...
