Caution
GHD Series pumps offer upgraded performance over G Series pumps for many applications; however, the following points need be considered in its selection:
1. GHD Series pumps operate over a wide range they can attain very low ultimate vacuum (10-2 Pa) and use KF flanges which are designed to achieve high vacuum. Use of high vacuum flanges is recommended for best performance.
2. GHD Series pumps are not recommended for applications involving toxic or corrosive gases. (See GCD Series).
3. An oil-sealed rotary pump is not recommended for continuous operation near atmospheric pressure.
