Difference Between Oil-less Rotary Vane and Dry Vacuum Pump
- Data Sheet
| Characteristics | Oil-less Rotary Vane Pump | True Oil-free Dry Vacuum Pump |
| Lubrication Mechanism | Graphite-vane self-lubrication | Absolute dry-running (zero lubricant) |
| Structural Principle | Rotating vanes + stator chamber | Multi-stage claw/scroll engagement |
| Vacuum Depth | Medium-High (0.1-1 Torr) | Ultra-High (≤0.001 Torr) |
| Solvent Vapor Resistance | Direct tolerance (graphite resists solvents) | Exceptional tolerance (all-metal/ceramic) |
| Maintenance Cost | Low (self-compensating wear) | Ultra-low (no consumables) |
| Price Range | $1,000-5,000 | $10,000-50,000+ |
| Cannabis Distillation Application | Industrial CBD refining (90-98% purity) | Pharmaceutical-grade CBD/CBG isolation (>99.9% purity) |
A vacuum pump removes gas molecules from a sealed space to form a vacuum or a state of low pressure. Vacuum pumps achieve critical cannabis extraction processes.
Lowering boiling points: THC distills at 80°C instead of 157°C under 0.1 Torr vacuum
Accelerating filtration/concentration: Negative pressure drives rapid separation
Recovering solvents: Closed-loop systems capture ethanol/butane for reuse.
A: HiURTB oil-free industrial vacuum pump has the following advantages for cannabis extraction.
* Contamination-proof operation
* Water-sealed pumps eliminate oil leaks
* Graphite-lubricated vanes resist solvent-induced emulsification
* Corrosion defense
* PTFE+fluororubber fusion coating (FDA 21 CFR 177.1550)
* 50% longer lifespan in butane/ethanol environments
* GMP compliance assurance
* USP <467> residual solvent compliance documentation included
For peak efficiency in cannabis processing, dedicated vacuum pumps are recommended:
- Rotary Evaporation Solvent Recovery
SHZ-B Water Circulation Pump: 4-port oil-free design, 60L/min flow
- Short Path Distillation (90-98% CBD Purity)
Oil-less Rotary Vane Pump: 0.1 Torr vacuum, graphite vapor resistance
- Medical-Grade Distillation (99.9%+ Purity)
Oil-Free Dry Claw Pump: 0.001 Torr vacuum, final cannabinoid isolation
A: HiURTB water circulation pump features:
Water-sealed vacuum generation: Rotating impeller creates vapor-free vacuum (0.098MPa)
Multi-port parallel suction: 4 independent taps serve multiple evaporators simultaneously
PTFE-coated fluid path: Direct ethanol vapor handling without cold traps
A: A Vacuum pump for distillation ensures purity and yield.
Precise vacuum control: 0.001 Torr (dry claw) vs. 0.1 Torr (oil-less vane) for cannabinoid separation
Zero contamination: Oil-free operation meets USP <467> solvent limits
Corrosion resistance: PTFE+fluororubber coating withstands butane/ethanol mixtures
A: HiURTB vacuum pumps integrate a triple-defense coating system:
Base Layer (50μm PTFE Plasma Spray)
Seals micro-pores in vacuum pump metal surfaces, preventing electrochemical corrosion
Mid Layer (80μm Fluoropolymer)
Absorbs thermal stress during vacuum pump start-stop cycles, eliminating cracking
Top Layer (30μm SiO₂-Reinforced PTFE)
Resists abrasive solvent particles in vacuum pump flow paths (ASTM D4060 Level H3)
