Impeller impeller open, closed, semi open in the end what is the difference?
Closed impeller in the impeller at both sides of the blade, front and rear cover, high efficiency, suitable for the delivery of clean liquid without impurities. The general centrifugal pump impeller is mostly such.
Half open impeller has no cover at one side of suction port, and cover plate on the other side. It is suitable for conveying material that is easy to precipitate or contains particles, and the efficiency is lower. General slurry pump for this type.
Water pump impeller, open, closed, semi open difference:The open impeller has no cover plate on both sides of the blade. The utility model has the advantages of simple manufacture and convenient cleaning, and is suitable for conveying materials containing relatively large amount of suspended substance. The efficiency is low, and the pressure of the liquid transported is not high. General delivery pumps for this category.
