Large head lotion pump with unique styles and various colors

A screw pump (also known as a helical rotary pump or progressing cavity pump) is a type of positive displacement pump that uses the principle of a rotating screw to move fluid. The screw's Archimedean screw-type design traps fluid in the cavities formed between the screw and the pump wall, progressively moving the fluid along the pump's axis. Here are some key features and applications:

Key Features

• Positive Displacement: Moves fluid by trapping a volume of it and forcing it through the system.
• Continuous Flow: Provides a continuous flow of fluid regardless of variations in pressure.
• Low Shear: Gently handles fluids, minimizing damage to shear-sensitive materials.
• Energy Efficiency: Generally more energy-efficient than other positive displacement pumps.

Applications

• Sludge and Slurry Transport: Effective for pumping viscous, abrasive, and shear-sensitive materials like sewage and drilling mud.
• Chemical Processing: Ideal for handling corrosive or hazardous chemicals, due to its low-shear and self-priming capabilities.
• Water and Wastewater Treatment: Used for handling raw and treated sewage, as well as various wastewater treatment processes.

Types of Screw Pumps

• Single Screw Pumps: Consist of one rotating screw inside a stationary housing with a cavity that moves the fluid.
• Twin Screw Pumps: Feature two intermeshing screws rotating in opposite directions, often used in higher-pressure applications.
