CDK turbomolecular pumping systems are completely oil-free. It incorporate an oil-free SST turbomolecular pump using dry-running, solid-lubricated ceramic bearings. The backing pump is an oil-free diaphragm vacuum pump.

• Unique, built-in automatic shut-off device for the backing pump
• User friendly
• Automatic shut-off device for the backing pump
• Lightweight, compact and portable

If the pump system works continually at the ultimate pressure, and if the connected vacuum system has a low real and virtual leak rate (wall degassing), then it is possible that the backing pump will remain switched off for hours.

The CDK systems have all components housed inside a casing, making them very compact and portable. The components include turbomolecular pump, backing pump, controller, and connecting tubing. A simple On/Off button makes operation simple. CDK systems employ three-stage chemical duty diaphragm pump as the backing pump.
