This chemistry vacuum pumping unit is an economic space-saving solution for simultaneous operation of two independent vacuum applications with one single pump. Based on our popular MD 4C NT three-stage chemistry diaphragm pump, the PC 611 select is frequently used for vacuum applications involving even high boiling point solvents. This pump has sufficient capacity for parallel operation of two demanding applications. One application is controlled by the VACUUSELECT vacuum controller an electronic solenoid valve. The second application is controlled by a manually controlled diaphragm valve. Both vacuum ports have integrated check valves to protect against cross contamination and interference.
The integrated VACUU•SELECT controller provides an easy-to-use, application based interface that covers all common lab applications. The VACUU•SELECT controller has you covered. Use manual set-point-control for simple processes, run distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, it detects the boiling pressure and switches to 2 point control mode to hold the pressure stable when a boiling point is detected. The inlet separator, made of glass with a robust protective coating, prevents particles and liquid droplets from entering the pump, preventing damage and extending pump life. And the exhaust vapor condenser allows for nearly complete recovery of solvents when used with a chilled water line or recirculating chiller for economical recycling and environmental protection.

Performance features
• VACUU•SELECT vacuum controller with graphical user interface simplifies work in the laboratory
• predefined applications save time and give reproducible results
• easy-to-use application editor allows own process sequences
• meets high vacuum requirements for most high boiling solvents
• PC 611 select allows simultaneous operation of two independent vacuum applications

The PC 3004 VARIO select pumping unit precisely controls the vacuum level in order to achieve unparalleled process control. With its high pumping speed and deep ultimate vacuum, this pump is suitable for demanding applications with even high boiling point solvents.

The integrated VACUU•SELECT controller provides an easy-to-use, application based interface that covers all common lab applications. The VACUU•SELECT controller has you covered. Use manual set-point-control for simple processes, run fully automated distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, the VACUU•SELECT controller continuously detects the boiling point and automatically adjusts the vacuum process as necessary.

And the VARIO control algorithm maintains the desired vacuum level without running the motor faster than necessary. This prevents bumping and foaming, makes the pump whisper quiet, and extends maintenance intervals.

The MD 12 NT diaphragm pump is an especially powerful pump for oil-free evacuation and pumping of non aggressive gases. The three-stage design of this eight-cylinder pump provides the advantageous combination of very high pumping speed and excellent ultimate vacuum. The flow path consists of aluminium, stainless steel and carefully selected plastics to permit a wide range of applications. The fabric-reinforced double diaphragms are made of highly flexible FKM for extended operating life and high vacuum performance. Eight-cylinder NT pumps feature quiet operation, with smooth and easy-to-clean surfaces. Like all VACUUBRAND diaphragm pumps they operate absolutely oil-free and do not have any sliding components in the gas path. In normal operation they are completely free of abrasion. This eliminates most of the particulate impurities frequently generated inside of scroll or piston pumps.

Performance features
• contamination-free pumping and evacuation
• high flow rate even near ultimate vacuum
• whisper quiet
• reduced process times
• exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs

Three-stage chemistry diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet the highest requirements. The three-stage design of the eight-cylinder MD 12C NT pump provides the advantageous combination of high pumping speed and very low ultimate vacuum. All internal parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms provide increased reliability and extended operating life. With its gas ballast valve the MD 12C NT is optimally prepared for pumping easily condensable vapors, thanks to the very good ultimate vacuum even with open gas ballast valve also for high boiling solvents. Upgrade kits such as inlet separator (AK) and exhaust vapor condenser (EK) enable a later adaptation to changed process requirements. Eight-cylinder NT pumps features quiet operation with smooth, easy-to-clean surfaces.

Performance features
• outstanding chemical resistance and superior vapor tolerance
• reduced process time due to particularly high pumping speed even near ultimate vacuum
• whisper quiet and very low vibration
• very good ultimate vacuum even with open gas ballast valve for condensate purge
• long diaphragm lifetime, maintenance-free drive system
