Generally speaking, for the transportation of liquids with different viscosities, rotor pumps have unparalleled advantages compared to other types of pumps. However, in liquid transportation, it is not only a matter of viscosity, but also often accompanied by high temperature, high pressure, and sometimes corrosive or solid particle containing characteristics. Therefore, when selecting a rotary pump, the following requirements must be considered:
1) The flow rate of the conveyed liquid and the applicable range of viscosity for the selected pump.
2) For occasions with measurement requirements, the selected pump has good performance stability when viscosity and other process conditions change.
3) The back pressure of the system and the applicable pressure range of the selected pump.
4) Inhalation performance, suction performance at high viscosity.
5) High temperature resistance, corrosion resistance, etc.
6) Simple structure, easy to disassemble, clean, and maintain.
