Ceramic is a kind of material with excellent corrosion resistance and wear resistance. The ceramic pump is based on this performance. The pump body and pump cover are made of acid-resistant ceramics. Ceramic pumps for chemical industry are generally centrifugal pumps, and their impellers, volutes, shaft seal chambers, and suction and discharge nozzles are all made of ceramics. At present, alumina ceramics are mainly used. It is suitable for transporting strong corrosive liquids such as hydrochloric acid, sulfuric acid, nitric acid, etc. It cannot transport fluorine-containing materials and concentrated lye. The flow rate of the ceramic pump can reach 400m3/h; the head can reach 50m; the operating temperature is -15"100°C; the sudden change temperature value is ≤50°C. Ceramic pumps are often protected by "armor" made of cast iron.

Vertical ceramic pump ceramic is a kind of corrosion resistance and wear resistance excellent material, ceramic pump is to learn from this performance, pump body and pump cover made of acid-resistant ceramic. Ceramic pump for chemical industry is generally centrifugal pump, its impeller, volute, shaft seal cavity and suction, discharge nozzle are made of ceramic. At present, alumina ceramics are mainly used. Suitable for conveying hydrochloric acid, sulfuric acid, nitric acid and other corrosive liquid, can not transport fluorine-containing materials and concentrated lye. Ceramic pump flow up to 400m3/h; Up to 50m; Operating temperature -15 "100°C; Temperature resistance ≤50°C. Ceramic pumps are often protected by cast-iron "armor" mounted on the pump.

Impeller refers to a wheel with moving blades, is an integral part of the impulse turbine rotor, and can also refer to the general term of the wheel and the rotating blades mounted on it. Impeller can be classified according to shape and opening and closing condition.

The riser is composed of a pipe and a flange, and the flange is welded to the upper end of the pipe; It is characterized by the composite structure of the pipe wall, composed of ceramic inner layer, refractory layer, steel pipe layer, asbestos cloth layer and glass fiber cloth layer, ceramic inner layer for refractory layer, refractory layer for steel pipe layer, steel pipe layer for asbestos cloth layer, asbestos cloth layer for glass fiber cloth layer.
