LABOPORT-SD, chemically resistant - Diaphragm vacuum pumps with self-drying system for the vacuum drying.
Dry-running positive-displacement pumps for neutral to highly aggressive gases and vapors. The process gases are not contaminated. The pumps create a constant vacuum.
The new KNF self-drying system allows condensed liquid to be blow out of the pump heads at high speed during evacuation. The vacuum in the recipient constant. The drying cycle can be adjusted to the requirements of the individual process using three variables. After drying, the pump reaches a better vacuum and is able to evacuate significantly faster compared with pumps without a drying system.
