A screw pump is a positive displacement pump that uses the rotation of a screw to push liquid from the suction end to the discharge end. Its features include:
1. High efficiency and stability: Screw pumps provide uniform flow and minimal pressure fluctuations, making them suitable for conveying high-viscosity liquids.
2. Strong self-priming capability: Capable of self-priming liquids in a short time, suitable for viscous media or media containing solid particles.
3. Compact structure: Small size, light weight, and easy installation and maintenance.
4. Low noise: Smooth operation and low noise, suitable for noise-sensitive environments.
5. Wide range of applications: Can be used to convey liquids of various viscosities, including oils and chemical liquids.
6. Corrosion resistance: Depending on the material, it can withstand various corrosive media.
7. Long service life: Due to low wear, it has a long service life. Screw pumps are widely used in the petroleum, chemical, food, and pharmaceutical industries.
