What are the classification of impeller in centrifugal pump

Centrifugal pump is widely used and is one of the most widely used.Impeller has closed type, open type and semi-open type.Daily life often use GD, GDR pipeline centrifugal pump (daily life water supply, fire control and general water supply system, refrigeration and air conditioning systems, etc.), GDD type pipeline centrifugal pump (can be used in the tap water pressure, the agriculture water supply and drainage, etc.), the VP (F) type vertical multistage centrifugal pump (water used in the hotel, deep well pump, seawater and fresh water delivery).For chemical industry, it can use IS, IZ, ISR type single-stage single suction water centrifugal pump (for water delivery and physical and chemical properties).

Centrifugal pump is mainly composed of impeller, pump body, pump cover, sealing ring, shaft sealing device, bracket and balance device.The impeller has an important role in the flow and lift of centrifugal pump.The centrifugal pump can carry liquid, which mainly depends on the high speed of the impeller in the pump, which causes the water to produce a great centrifugal force, thus conveying the liquid.The size, shape and manufacturing accuracy of impellers play an important role in the flow and lift of centrifugal pump.
