VARIO® chemistry pumping unit in action
VARIO® pumps and pumping units provide precise vacuum control by adaptation of the diaphragm pump´s motor speed. They feature fully automatic evaporation control on the push of a button. The basic pump is the MZ 2C NT VARIO two-stage chemistry diaphragm pump which meets medium vacuum requirements for most solvents. The pumping unit PC 3002 VARIO is a well proven choice for evaporation of large amounts of solvents. The separator at the inlet collects particles and liquid droplets. The waste vapor condenser Peltronic® at the outlet enables near-100-percent solvent recovery, efficient recycling and active environmental protection without external coolant. The on-demand motor speed control results in unsurpassed lifetimes of service parts, such as diaphragms. Typical applications are all evaporation processes. Evaporation processes can be run fully automatically and with short process times and high sensitivity at the same time. The VARIO® control ensures high process reliability through prevention of superheating or foaming. The control allows for automatic vacuum level adaptation and is self-adapting to changing process parameters at any time.
