MD 4C NT VARIO
VARIO® pumps provide precise vacuum control by adaptation of the diaphragm pump's motor speed. The three-stage chemistry MD 4C NT VARIO diaphragm pump meets high vacuum requirements for most high boiling solvents. The on-demand motor speed control results in unsurpassed lifetimes of service parts, such as diaphragms.
Performance features
- automatic adaptation of the vacuum level throughout the process for high process reliability and unattended operation
- short process times due to high pumping speed and zero-fluctuation (hysteresis-free) vacuum control
- easily operated CVC 3000 vacuum controller with clear text menus, with integrated venting valve
- extraordinary diaphragm life, therefore minimum operational and servicing costs
- excellent chemical resistance
