Scroll Pumps
Scroll pumps, also known as scroll compressors or scroll vacuum pumps, are positive displacement pumps that use spiral-shaped scrolls to compress or pump fluids. These pumps are widely used in various applications, including vacuum systems, refrigeration, and air conditioning. Here are some key features and considerations regarding scroll pumps:
-
Scroll Mechanism:
- Scroll pumps operate on a unique mechanism involving two interleaved spiral scrolls. One scroll remains stationary while the other orbits, creating moving pockets that progressively decrease in size, compressing the fluid.

Oil-Free Operation:
- Many scroll pumps are oil-free, making them suitable for applications where oil contamination is a concern. This feature is particularly advantageous in industries such as semiconductor manufacturing, where clean and oil-free conditions are essential.
