MD 12C
Description
MD 12C
Three-stage chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet the highest requirements. The three-stage construction of the eight head MD 12C pump provides the advantageous combination of high pumping speed and very low ultimate vacuum. All internal parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms for increased reliability and extended operating life. The PC 8 accessory kit offers upgrading to a system with solvent recovery.
Performance features
- outstanding chemical resistance and superior vapor tolerance
- exceptionally high performance even at low vacuum
- reduced process times
- excellent environmental friendliness due to efficient solvent recovery (with optional emission condenser)
- long diaphragm life, maintenance-free drive system
