What are the advantages of vertical single-screw pumps when conveying high-viscosity liquids?
2025-10-13 11:20:49

Vertical single-screw pumps provide stable flow with virtually no pulsation. This ensures continuous and stable flow when conveying high-viscosity liquids, thereby improving production efficiency and product quality. Screw pumps can handle not only low- to medium-viscosity liquids but are also well-suited for high-viscosity, high-concentration liquids such as pastes, colloids, and multiphase fluids. This wide adaptability enables vertical single-screw pumps to perform exceptionally well in a wide range of industrial applications.

Vertical single-screw pumps can handle liquids containing solid particles and offer strong conveying capacity. This is particularly important when conveying high-viscosity liquids containing solid impurities or particles, ensuring long-term, stable operation of the pump. The efficient sealing chamber design between the screw and the pump casing ensures pump performance and safe operation. When conveying high-viscosity liquids, effective sealing prevents leakage, thereby ensuring a safe and hygienic production environment.

Vertical single-screw pumps play an important role in a wide range of industries, including industry, agriculture, chemicals, petroleum, and food. Vertical single-screw pumps have become indispensable equipment, particularly in industries such as petrochemicals, environmental protection, exploration and mining, and pharmaceuticals and food.

The operating principle of vertical single-screw pumps also offers advantages in conveying high-viscosity liquids. The planetary rotation of the rotor (single-start screw) within the stator (double-start internal spiral bushing) creates a sealed chamber, allowing the medium to be continuously and smoothly transported axially from the suction end to the discharge end. This operating principle gives vertical single-screw pumps greater efficiency and stability when conveying high-viscosity liquids.
