Can transport high-viscosity fluid: Because the impeller of screw pump is spiral, it can transport high-viscosity fluid, such as asphalt, heavy oil and lubricating oil, while centrifugal pump is not good at transporting high-viscosity fluid.
No pulsation and low noise: the screw pump has stable flow, no pulsation and impact, and low noise during operation, which is suitable for occasions with high requirements on flow and noise such as medical equipment and food processing.
High pressure: Screw pump can transport high-pressure liquid, generally reaching 30-40bar, while centrifugal pump has a relatively low pressure range.
Scope of application: Screw pump is suitable for liquid transportation, pressurization, transportation of high-temperature liquid, viscous liquid, solid-containing liquid and so on. , and has a wide range of applications.
It should be noted that the screw pump also has some disadvantages, such as not being able to transport low-viscosity fluids such as pure water and not being able to transport liquids containing particles. When choosing a pump, we should comprehensively consider the characteristics and application scope of different types of pumps according to the actual needs and conditions, and choose the appropriate pump type.
