Chemical pump according to the principle of different. Vane pumps, positive displacement pumps, fluid power pumps and special pumps for chemical engineering :
1. Vane pump
This type of pump is used to interact with the blade and liquid, to the liquid with a centrifugal force or axial force to transport or pressurized liquid. Such as centrifugal pump, mixed flow pump, axial flow pump, vortex pump, centrifugal vortex pump, etc.. Centrifugal pump and vortex pump used in the chemical industry.
2. Volume type pump
It is based on the periodic changes in the pump working chamber volume liquid suction pressure. This kind of pump has reciprocating pump, gear pump, screw pump and pump and so on.
3. Fluid power pump
Rely on another so-called "working fluid" as a driving force to transport liquid, such as jet pumps, acid eggs (also known as the acid) and so on. With this pump to pump I suction or compression flammable and explosive, corrosive material is very safe.
4. Special pumps for chemical industry
The working principle of special chemical pump still belongs to the category of centrifugal pump. Just according to the operating conditions and liquid properties and the degree of adverse selection by some special materials or structures. Such as glass, plastic pump pump pump, ceramic pump, Shi Mobeng, shield pump, pipeline pump, high speed liquid ammonia pump, cryogenic pumps and pump etc..
