How It Works
The pump operates through a multi-head positive displacement mechanism that creates vacuum by removing air and gases from connected vessels. The 4-head configuration provides consistent vacuum generation at -0.098 MPa while the 10 L/min evacuation speed ensures efficient removal of gases and vapors. The vacuum level is maintained through mechanical displacement of air volume.
Simultaneously, an integrated circulating pump delivers 40 L/min water flow through the system's 15 L reservoir. This circulating water can be used for temperature control of connected equipment, cooling condensers, or maintaining thermal stability during vacuum operations. The water circulation operates independently of the vacuum function, allowing for precise temperature management.
The anti-corrosion materials in the pump construction ensure compatibility with various laboratory chemicals and resistance to degradation from water circulation and exposure to vapors during vacuum operations.

| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Vacuum Level | -0.098 MPa ultimate vacuum | Entry-level pumps often achieve -0.08 to -0.09 MPa | Provides sufficient vacuum depth for most laboratory applications including filtration and moderate distillation requirements |
| Evacuation Rate | 10 L/min evacuation speed | Basic pumps typically offer 5-8 L/min rates | Faster evacuation reduces processing time and improves throughput for repetitive vacuum operations |
| Water Circulation Flow | 40 L/min circulation rate | Standalone circulators often provide 20-30 L/min | Higher flow rate enables more effective temperature control and heat exchange for temperature-sensitive processes |
| Water Capacity | 15 L reservoir capacity | Compact units commonly offer 8-12 L capacity | Larger capacity reduces refill frequency and provides better thermal stability during extended operations |
| Pump Configuration | 4-head pump design | Single or dual-head configurations are common | Multiple heads reduce pulsation and provide more consistent vacuum for sensitive analytical procedures |
| Integrated Design | Combined vacuum and circulation in single unit | Separate vacuum and circulation systems | Reduces bench space requirements and simplifies setup for applications requiring both vacuum and temperature control |
The pump combines substantial vacuum capability with high-flow water circulation in a single unit, offering space efficiency and operational convenience. The 4-head design and anti-corrosion construction provide reliability for demanding laboratory environments.
Practical Tips
Replace reservoir water weekly and clean the tank monthly to prevent algae growth and maintain circulation efficiency.
Why: Clean water prevents blockages in circulation lines and maintains heat transfer efficiency.
Allow the pump to run for 5 minutes before connecting sensitive equipment to achieve stable vacuum and circulation conditions.
Why: Initial stabilization ensures consistent operating conditions and prevents pressure fluctuations during critical procedures.
If vacuum level decreases, first check all connections for leaks before assuming pump degradation.
Why: Most vacuum issues result from connection problems rather than pump failure, making leak checking the most efficient diagnostic step.
Install a vacuum gauge and relief valve in the system to monitor pressure and prevent over-evacuation of fragile glassware.
Why: Pressure monitoring prevents equipment damage and provides early warning of system malfunctions.
Monitor water temperature during temperature-critical applications to ensure thermal control effectiveness.
Why: Temperature stability directly affects reproducibility in temperature-sensitive analytical procedures.
Verify vacuum level monthly using a calibrated vacuum gauge to ensure performance specifications are maintained.
Why: Regular calibration verification ensures measurement accuracy and early detection of performance degradation.
Position the unit to minimize vibration transmission to sensitive analytical equipment through proper isolation.
Why: Vibration isolation prevents interference with precision measurements and reduces mechanical stress on connected equipment.

Background reading relevant to this product:
What is the ultimate vacuum level achievable with this pump?
The pump achieves -0.098 MPa vacuum with 10 L/min evacuation speed, suitable for most laboratory filtration and distillation applications but may not be sufficient for high-vacuum requirements.
Can the vacuum and water circulation functions operate independently?
Yes, the vacuum generation and water circulation systems operate as separate functions within the same unit, allowing independent control of each system based on application requirements.
What type of water should be used in the circulation system?
Distilled water is recommended to prevent mineral buildup and corrosion in the circulation lines, particularly important given the anti-corrosion materials and long-term reliability requirements.
How does the 12m lift capacity affect installation options?
The 12m lift capability allows the pump to draw water from elevated reservoirs or supply circulation to equipment positioned well above the pump level, providing installation flexibility.
What maintenance is required for sustained operation?
Regular water reservoir cleaning, periodic inspection of vacuum lines for leaks, and monitoring of circulation flow rates are essential for maintaining performance specifications.
Is the pump suitable for continuous operation applications?
The 370W power consumption and anti-corrosion construction suggest suitability for extended operation, though duty cycle limitations should be verified for specific continuous applications.
What vacuum line connections are compatible with this pump?
Consult product datasheet for specific connection types and sizes, though standard laboratory vacuum fittings are typically accommodated.
