A typical circulating water vacuum pump operates at 180W with flexible power supply options (110V/60Hz or 220-240V/50-60Hz), designed for efficiency in lab and industrial settings. These pumps balance performance (80 L/min flow rate, 10m lift) with practical considerations like compact dimensions (385×280×420mm) and stainless steel/PVC construction for durability. Their ability to replace oil pumps while offering stable vacuum pressure (-0.098MPa) makes them ideal for processes like distillation and filtration across pharmaceutical, chemical, and research applications.
Key Points Explained:
-
Power Specifications
- Standard power consumption: 180W
- Voltage options:
- 110V (single-phase, 60Hz) – common in North America
- 220-240V (single-phase, 50/60Hz) – global compatibility
- Energy efficiency stems from:
- Direct water recycling (15L tank capacity)
- No oil lubrication required (unlike traditional vacuum pumps)
-
Performance Parameters
- Flow rate: 80 liters/minute – sufficient for most lab-scale operations
- Lift height: 10 meters – adequate for vertical fluid movement in typical setups
- Ultimate vacuum: -0.098 MPa (2 KPa) – comparable to oil pumps for standard applications
- Pressure tolerance:
- 1.0MPa standard (for ≤75m systems)
- Upgradeable to 1.6MPa or 2.5MPa for high-pressure needs
-
Design Advantages Over Oil Pumps
- Maintenance benefits:
- No oil changes or leaks (PVC/stainless steel construction)
- Easy cleaning (open reservoir design)
- Operational perks:
- 30% quieter operation than oil-based systems
- Water recycling reduces consumption by ~60% versus continuous feed systems
- Durability factors:
- PTFE-coated stainless steel impeller resists chemical corrosion
- Copper ejector ensures long-term thermal stability
- Maintenance benefits:
-
Selection Considerations for Buyers
- Flow rate matching: Calculate based on:
- Peak simultaneous equipment demand (e.g., multiple rotary evaporators)
- Additional 15-20% buffer for operational headroom
- Power compatibility: Verify lab electrical infrastructure:
- 110V systems draw ~1.6A (require dedicated circuit if used with other equipment)
- 220V systems draw ~0.8A (more energy-efficient for continuous operation)
- Pressure requirements: For high-vacuum applications:
- Confirm need for 1.6MPa/2.5MPa upgrades
- Consider head loss in complex piping layouts
- Flow rate matching: Calculate based on:
-
Typical Applications & ROI Factors
- Common uses:
- Rotary evaporation (pharma labs process ~50% faster than oil pumps)
- Vacuum filtration (handles 0.2μm membranes without cavitation)
- Freeze drying (consistent pressure for sample integrity)
- Cost savings:
- Eliminates $200+/year oil replacement costs
- 5-year lifespan vs. 3-4 years for oil pumps
- Space efficiency:
- 30% smaller footprint than equivalent oil pumps
- Mobile configurations available for shared lab spaces
- Common uses:
-
Material & Safety Features
- Critical components:
- Stainless steel 304 body withstands acidic/alkaline vapors
- PVC check valve prevents backflow (meets ISO 3821 standards)
- Safety systems:
- Automatic shutoff at 1.0MPa (prevent overpressure damage)
- Thermal cutoff at 70°C (protects motor during continuous use)
- Compliance:
- CE-certified electrical systems
- RoHS-compliant materials for international shipping
- Critical components:
For labs running daily vacuum processes, these pumps offer ~40% lower lifetime costs than oil-based systems while maintaining comparable performance. The dual voltage option makes them particularly valuable for multinational organizations standardizing equipment across facilities.
