Centrifugal impurity pump is used to convey liquid media, such as mud, ash, ore, sugar juice, feed, coal water, rubber particles, feces and other solid or suspended solids. It is widely used in chemical, mining, metallurgy, urban sewage treatment and other industries.
Impurity pumps require the overflow parts to have corresponding wear-resistant properties, and wear-resistant materials are often selected to meet the needs of various impurity pumps. In order to prevent the pump from being blocked, the impellers are all open, if the closed impeller is used, the width of the impeller should be increased or the number of blades should be reduced.
Centrifugal corrosion-resistant pumps for transporting corrosive liquids such as acids, alkalis, salts, etc. The overflow parts of the pump must be made of corrosion-resistant materials. These pumps are widely used in the chemical, petrochemical and defense industries. Centrifugal corrosion-resistant pumps are single-stage, single-suction cantilever structure.
Shielded pump, also known as packless pump, is a pump that directly connects the impeller to the rotor of the motor and works by immersing itself in the liquid being conveyed. The canned pump is a type of centrifugal pump, but it is different from the general centrifugal pump. The main difference is that in order to prevent the conveyed liquid from coming into contact with the electrical part, a special shielding sleeve (non-magnetic metal thin-walled cylinder) is used to isolate the rotor and stator of the motor from the conveyed liquid, so as to meet the need for absolutely no leakage of the conveyed liquid.
Since the canned pump can guarantee absolutely no leakage, it is especially suitable for conveying corrosive, flammable, explosive, highly toxic, radioactive and extremely valuable liquidsIt is also suitable for conveying liquids with high pressure, high temperature, low temperature and high melting point. Therefore, it is widely used in chemical, petrochemical, national defense industry and other industries.
