Screw pumps are powerful contenders among positive displacement pumps, utilizing the harmonious interaction between a helical rotor and stator to transport fluids. Unlike the rotary motion of centrifugal pumps, they push the medium from the inlet to the outlet like tightening a screw, making them particularly suitable for handling high-viscosity or particulate liquids. In industries such as petroleum, chemical, and food processing, this stable output characteristic makes them crucial in the transportation process.
Characteristics of Three Common Types of Screw Pumps:
Single Screw Pump: Simple structure, excellent at handling wastewater or sludge containing solid particles.
Twin Screw Pump: Stable flow rate, outstanding performance in lubricating oil transportation and hydraulic systems.
Three Screw Pump: Stable pressure output, ideal for oil-fired boilers and large machinery.
