🔄 Combination Systems – Rotary & Diaphragm Pumps
Welch offers innovative hybrid pump systems that combine the advantages of oil-sealed rotary vane pumps (deep vacuum) and diaphragm pumps (oil-free, chemically resistant).
🔀 ChemStar Hybrid Pump Systems
- ✓ Automatic switching between diaphragm and rotary vane pump
- ✓ Diaphragm pump for rough evacuation and aggressive vapors
- ✓ Rotary vane pump for deep ultimate vacuum
- ✓ Protection of rotary pump from corrosive vapors
- ✓ Extended service life of oil-sealed rotary vane pump
- ✓ Intelligent control via controller
💡 Advantages of Hybrid Systems:
Chemically aggressive processes are handled by the diaphragm pump, while the rotary vane pump is only used for clean final evacuation. This significantly extends the service life of the rotary pump and reduces maintenance costs.
Ideal Applications: Rotary evaporation with aggressive solvents, freeze drying, chemical synthesis, distillation of corrosive substances
