MD 4C NT VARIO

Description

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
