Scroll Pumps

13th Feb 2023

A dry scroll pump is a type of positive displacement pump that uses a pair of spirally-grooved scrolls to transfer fluid from the inlet to the outlet of the pump. The benefits of a dry scroll pump include:

  1. Dry Running: Dry scroll pumps do not require any liquid to be present in the pump chamber, making them suitable for use in applications where liquid is not always present.
  2. Low Noise: Dry scroll pumps are known for their low noise operation, making them ideal for use in applications where noise is a concern.
  3. High Vacuum: Dry scroll pumps are capable of generating high vacuum levels, making them suitable for use in vacuum applications, such as in semiconductor manufacturing and scientific research.
  4. Low Maintenance: Dry scroll pumps have few moving parts and are designed for low maintenance, making them cost-effective and easy to maintain.
  5. Energy Efficiency: Dry scroll pumps are highly efficient, consuming less energy compared to other types of pumps, which results in lower operating costs.

Industries that use dry scroll pumps include semiconductor manufacturing, scientific research, medical equipment manufacturing, environmental monitoring, and analytical instrumentation. These pumps are commonly used in applications where a high vacuum is required, such as in vacuum drying and degassing, and in applications where low noise is a concern, such as in laboratory and cleanroom environments.

The maintenance of a dry scroll pump typically involves regularly checking and cleaning the inlet and outlet filters, checking the oil level and quality, and monitoring the vibration and noise levels of the pump. In addition, the tip seal, which is a critical component that prevents fluid from leaking out of the pump, should be checked and replaced if necessary. It's important to use the correct type of tip seal for your specific pump and to follow the manufacturer's recommendations for replacement.

In summary, maintaining a dry scroll pump involves regularly checking and cleaning filters, monitoring vibration and noise levels, and checking and replacing the tip seal as needed. These steps can help ensure that the pump operates efficiently and effectively for many years.
