We mainly manufacturer two types of self priming pumps, self priming trash pump and engine driven slurry pump. Before work, the pump body and the inlet pipe must be filled with water to form a vacuum state, when the impeller rapid fast, the blade makes water rotation, rotating water under the action of the centrifugal force from the impeller, the pump water is thrown, vacuum area, the center of the water in the atmospheric pressure (or water pressure) through the pipe network pressure into the inlet pipe, so circulation, realize continuous pumping.
