Industrial self-priming centrifugal pumps are a product of vane type pumps. Since this kind of pump mainly transports liquid by the centrifugal force generated when one or several impellers rotate, it is called a centrifugal pump. As the name implies, Round Molded Graphiteis a cylindrical product of graphite electrode, which is made of graphite block materials by crushing, screening, batching, shaping, cooling, roasting, dipping and graphitization of post section petroleum coke and medium temperature coal tar pitch. It has the advantages of high temperature resistance, corrosion resistance, good conductivity and light weight. It is mainly used for large DC resistance furnaces, blast furnace bricks, conductive electrodes, lining anti-corrosion and other purposes.

Centrifugal pump classification is generally divided into the following methods:
(1) According to the number of impellers and the number of stages 1) Single-stage centrifugal pumps - there is only one impeller in the pump;
2) Multi-stage centrifugal pump - There are multiple impellers in the pump. One impeller is one stage. The more stages, the higher the lift.
(2) According to the impeller's suction liquid method 1) Single-suction centrifugal pump - the liquid is suctioned from one side of the impeller, which is both a single-stage centrifugal pump and a single-suction centrifugal pump;
Double Suction Centrifugal Pumps - Both sides of the impeller draw in liquid at the same time (3) In the form of a guide vane mechanism 1) Volute pump - A centrifugal pump like a snail shell.
2) Guide vane pump - The pump with several fixed vanes on the periphery of the impeller is a vane type pump. In the early days, this pump was called a turbine pump. Multi-stage pumps are mostly in this form.
(4) According to the type of pump joints 1) Pumps with horizontal seams (medium open type) - Pumps with pump joints on the horizontal plane through the centerline of the pump shaft.
2) Pump with vertical seam A pump with a pump cover mounted on the face perpendicular to the centerline of the pump shaft.
Single-stage pumps and segmented multi-stage pumps often use this form.
(5) according to the nature and use of liquid transport centrifugal pump, industrial self-priming centrifugal pump, centrifugal well pump, centrifugal oil pump, condensate pump, boiler feed pump and other special centrifugal pumps.
Industrial self-priming centrifugal pump classification is generally as described above. However, for a specific type of pump, it should be in accordance with national standards, industry standards and the unified name of China Mechanical and Electrical Products Directory. E.g. IS type single-stage single-suction cantilever centrifugal pump, the unified name is: IS type single-stage single-suction centrifugal pump.
