Vacuum pump units with a two or three-stage chemistry diaphragm pump. Compact construction with chemistry diaphragm pump on base plate, separator on suction side made of glass with protective coating (AK), one or two electromagnetic chemistry valves on the suction line, exhaust waste vapour condenser with collecting flask, and one or two CVC 3000 vacuum controllers on the controller support.

• Oil-free vacuum down to 1,5 mbar
• With vacuum-controller CVC 3000 for optimum vacuum control and regulation
• Two solenoid valves on the suction line (24 V)
• Equipped with chemistry diaphragm pumps with high chemical resistance (parts in contact with media are made from PTFE compounds and similar)
• Insulated exhaust waste vapour condenser with shared intensive separation of all vapour fractions that condense at cold water temperature and atmospheric pressure

This vacuum pump unit has two separate and automatically controllable vacuum connections, each with its own CVC II vacuum controller. This enables automatic vacuum regulation in two independent applications. Built-in non-return valves to prevent processes from interfering or contaminating each other.
