Vacuum Pump Rotavac Valve Control --

Suitable for all Hei-VAP Rotary evaporators. Vacuum can be controlled manually or via valve operated vacuum controllers.

• With two-stage diaphragm pump
• All components which come in contact with media are built from chemically resistant fluoropolymer
• The durable PTFE design guarantees an superior diaphragm lifespan
• The head cover and clamping disc have a stable core made of metal which offers unsurpassed long-term performance of your operational parameters
• The direct pump drive (without belt) is exceptionally quiet, creates a very low vibrational environment and reduces the need of wear and tear parts to a minimum
• The gas ballast valve has been optimized to prevent media condensing in the pump
• The pumps can be combined with a condenser
• For combination with the Hei-VAP Precision Rotary evaporators a vacuum valve is necessary.

• Suction capacity for up to 3 rotary evaporators at the same time
• Depending on your application you can switch on and off the vacuum pump via switchbox
