Chemistry design diaphragm pumps are ideal for continuous, oil-free pumping of corrosive gases and vapors. The two-stage construction provides the advantageous combination of medium pumping speed and low ultimate vacuum.

• PTFE sandwich diaphragms for increased reliability and extended operating life
• Major parts in contact with pumped media are made of chemically resistant fluoroplastics

Pumps provide precise vacuum control by adaptation of the diaphragm pump motor speed.
