Impeller Centrifugal Pump, pumps air & liquid breakthrough US patent



US patent 8967274 Self Priming Pump



By using this invention we can make an average water pump with impeller to form a Cooling system, compressor or self priming pump, It is low cost less malfunctions easy to repair, long life.






The present invention solves problems related to pump priming by adding two tanks and two "magic" pipe switchers so that a pump can draw air for as long as necessary until liquid arrives, and if the liquid is mixed with some air, for example, due to air leakage in the supply pipe, the pump can pump liquid as if there were no air present. The pump can be situated anywhere convenient to the user.

When air goes into a centrifugal pump, it can cause the pump to stop pumping water, because the centrifugal impeller cannot efficiently pump air and suck water from a supply pipe. If the water source is far away from the pump, it cannot efficiently pump water until the entire length of the source pipe is filled with water. A pump full of air may not be able to generate enough pressure difference to draw water into the pump. If some air bubbles are present in the long pipe, these air bubbles can combine to form an air pocket which can stop the pumping of water. Therefore it is common practice to position centrifugal pumps close to the water source (e.g., a river or lake). In the case of wells, the pump is positioned at the bottom of the well to make the distance between the centrifugal pump and the water source as short as possible.
