The sucking rate for a single tap on a water circulating vacuum pump is 10 liters per minute (L/min). This rate is achieved through the pump's unique water-ring vacuum mechanism, where an eccentrically mounted impeller creates periodic volume changes to draw in and expel gas. While this specification is standard, the pump's actual efficiency ranges from 30% to 50%, depending on the model. Key operational parameters like flow rate (80 L/min), lift height (10 meters), and ultimate vacuum capacity (-0.098 MPa) further define its performance. For purchasers, understanding these metrics ensures alignment with lab needs, balancing suction power with energy use and maintenance requirements.
Key Points Explained:
-
Sucking Rate Fundamentals
- The 10 L/min per tap rate is achieved through the pump's centrifugal water-ring mechanism:
- Water acts as the working fluid, forming a rotating ring inside the pump casing.
- An eccentrically installed impeller with curved blades creates expanding and contracting cavities, drawing in gas during rotation.
- Why it matters for purchasers: This design ensures consistent suction without oil or mechanical seals, reducing contamination risks in sensitive applications like pharmaceuticals or food processing.
- The 10 L/min per tap rate is achieved through the pump's centrifugal water-ring mechanism:

Efficiency Considerations
- Typical efficiency ranges from 30% to 50% (higher-end models).
- Factors affecting efficiency:
- Water quality and temperature: Impurities or high temps can reduce the water ring’s stability.
- Impeller wear: Over time, blade erosion diminishes suction performance.
- Purchaser insight: Opt for models with corrosion-resistant materials if used with aggressive chemicals.
-
Operational Parameters
- Flow rate: 80 L/min total capacity (supporting multiple taps).
- Lift height: 10 meters, critical for applications requiring water circulation (e.g., cooling condensers).
- Vacuum limit: -0.098 MPa (20 mbar), suitable for most lab distillation or filtration tasks.
- Key question: Does your workflow require simultaneous use of multiple taps? If so, ensure the total flow rate meets peak demand.
-
Design and Maintenance
- Water tank capacity: 15 liters, balancing refill frequency with footprint.
- Safety features: Built-in check valve prevents backflow.
- Maintenance tip: Regularly replace water to prevent mineral buildup, which can clog the impeller.
-
Comparative Advantages
- Unlike oil-based vacuum pumps, water-ring pumps:
- Eliminate oil vapor contamination.
- Are quieter and more energy-efficient.
- Trade-off: Lower ultimate vacuum pressure vs. rotary vane pumps.
- Purchaser decision point: Prioritize cleanliness and simplicity over ultra-high vacuum levels? This pump excels.
- Unlike oil-based vacuum pumps, water-ring pumps:
-
Real-World Implications
- In a lab setting, the 10 L/min rate translates to:
- Rapid evacuation of standard filtration setups (e.g., Büchner funnels).
- Support for continuous processes like rotary evaporation when paired with adequate cooling water flow.
- Cost consideration: Higher efficiency models (50%) may justify a premium price through reduced energy consumption over time.
- In a lab setting, the 10 L/min rate translates to:
By matching these technical specs to your lab’s daily operations—whether for chemical synthesis, sample preparation, or equipment cooling—you can optimize both performance and long-term value. Always factor in total cost of ownership, including water usage and maintenance labor, when comparing models.
