Vacuum controllers

A lot of applications in the laboratory call for electronic vacuum control, that is, constantly adapting the pump´s volume flow rate to process requirements. The maximum volume flow rate of the unregulated pump can be changed in various ways:

  • by cyclically turning the pump on/off (with CVC 3000 controller with module VMS-B)
  • by cyclically opening/closing an in-line solenoid valve (CVC 3000) or
  • by changing the pump´s motor speed continuously (VARIO® pumps in connection with CVC 3000)

The controller can be used both in vacuum networking solutions where parameters are set once for controlling the vacuum or as a stand-alone controller. The CVC 3000 with its large display, the user-friendly full-text menus and the stable stand is also perfect for use on the lab bench.

Many accessories can be easily connected to vacuum controllers: A coolant valve, an external venting valve or a liquid level sensor for catchpots are often required. Communication with sensors, VARIO® - pumps, the Peltronic® condenser and all other connected components takes place via the VACUU·BUS® control system. It is self-configuring, meaning that connected components will be automatically detected, configured and monitored by the vacuum controller. The self-configuration of the vacuum controllers due to the VACUU·BUS® system makes them especially user-friendly and rules out any mix-up of components. Chemically resistant IP 67 connectors allow the connection of many components.



  • self-configuring plug and play
  • sealed plugs highly resistant to chemicals
  • no danger of getting plugs confused
  • connect almost any number of components
