Vacuum Pumps 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.
Vacuum Pumps Rotavac Vario Control
Suitable for Rotary evaporators Hei-VAP series. Controllable vacuum pumps for digital regulation of the vacuum via operation panel or directly at the unit.
- High distillation rates and reduced process time by 30 %.
- Solvent recovery up to 99 %.
- Pump stops automatically as soon as the set vacuum is reached and reliably holds the vacuum constant
- Increased diaphragm performance life due to periods of non-operation
- Low energy consumption
- Significant noise and vibration reduction
- The pumps can be combined with a condenser
Vacuum Pumps Rotavac Vario Pump Unit
Suitable for Hei-VAP Core. Fully controllable stand-alone pumping unit including vacuum controller
- 3-stage diaphragm pump is made from chemical-resistant material
- High suction capacity for fast evacuation
- Precise vacuum control avoids bumping and eliminates foaming of your evaporation solution
- Automatic vacuum supply to the process parameters
- The pump unit can be combined with a condenser
