A single-screw pump is like a gentle liquid conveyor belt, its core being the perfect pair: The rotor and stator. The rotor, like a tightly wound spring, rotates within a spiral channel formed by the rubber stator, propelling the liquid forward by one screw pitch with each revolution. This design allows even viscous liquids to move smoothly, like slowly screwing a screwdriver into butter.
The liquid journey is completed in three steps:
Capture Stage: Negative pressure is created at the inlet, drawing the liquid into the spiral-sealed chamber.
Escort Stage: The rotating rotor propels the liquid steadily along the axial direction.
Release Stage: Continuous spiral motion smoothly pushes the liquid out of the outlet.
A Gentle Giant in Industry
This pump is particularly suitable for handling sensitive fluids:
It won't damage the original structure of the liquid, like drinking bubble tea with a straw without breaking the tapioca pearls.
Stable flow with minimal pulsation, comparable to a high-speed train traveling at a constant speed.
Strong self-priming capability, it can run dry for tens of seconds without issue.
It can handle mixtures containing solid particles, similar to how the blades in a blender don't contact the cup wall.
