Shear pump is developed on the basis of existing centrifugal pump theory via some improvement to develop a new and efficient centrifugal pump. It is designed for quick preparation and disposal of drilling fluids in the solids control system. The main application is to shear polymer clay, it can mix materials effectively, fully hydrate materials, save materials, shorten drilling fluids preparation time, supply good drilling fluids performance to drilling operations.
KOSUN Shear Pump's impeller is specially designed to have a wider flow pass and smooth vanes, with larger flow area and smooth fluids pass, making the shear pump reach the internationally advanced level in efficiency and energy saving which is 10% higher than similar products. The shear pump has adopted a shell thicker than the normal one, with rational pass and less turbulence.


KOSUN Shear Pump's impeller and shell are made of highly wear-resistant cast irons, with longer service life. The shear pump shaft has high strength that can bear certain load, reduce shafts deflection and extend seals service life. The shaft is lubricated with lubricants and lubricating grease and the oil seal is made of special structure and materials. It is suitable for high and low temperatures as well as complicated environment. Front opening structure is used for convenient installation, repairing and maintenance.
SP Series Shear Pump is the equipment of special purpose in the solids control system which can meet all customers’ requirements of preparing dilling fluids for the well drilling. This shear pump manufactured by KOSUN is used to treat the high property mud, make the mud obtain good rheological properties and cut the drilling cost as much as possible. This ideal solids control equipment designed by KOSUN’s engineers has high performance and has been highly spoken of by customers.
