Single Screw Pump
A Single Screw Pump is a type of positive displacement pump that uses a helical rotor turning inside a stator to transfer fluid. It is widely known as a Progressive Cavity Pump and is especially effective for handling viscous, abrasive, or shear-sensitive fluids.
⚙️ Working Principle
The pump consists of:
- A helical metal rotor (usually single-threaded)
- A double-helix stator made of elastomer material
As the rotor turns inside the stator, a series of sealed cavities progress from the suction to the discharge end. These cavities move the fluid smoothly, continuously, and with minimal pulsation.
