Circulating water vacuum pumps are essential for creating negative pressure in various laboratory and industrial processes, offering a clean, oil-free alternative to traditional vacuum pumps. Key performance parameters include a flow rate of 80 L/min, a lift of 10 meters, and an ultimate vacuum of -0.098 MPa (2 KPa). These pumps feature two taps with a single tap air suction amount of 10, a 15-liter water tank, and compact dimensions (385mm × 280mm × 420mm) weighing 11 kg. With a power of 180W and efficiency ranging from 30% to 50%, they are widely used in evaporation, distillation, and filtration applications across chemical, pharmaceutical, and food industries.
Key Points Explained:
-
Flow Rate (80 L/min)
- This measures how much water the pump can circulate per minute, directly impacting its ability to maintain consistent vacuum levels.
- Why it matters for purchasers: Higher flow rates support continuous operations like large-scale distillation or multi-user lab setups. For intermittent processes (e.g., vacuum filtration), a lower flow rate may suffice, reducing energy costs.
- Practical consideration: Calculate total water needs—including auxiliary processes like cooling or waste discharge—to avoid under/over-specification.
-
Lift Height (10 meters)
- Indicates the vertical distance the pump can move water against gravity.
- Why it matters: Must align with system requirements (e.g., boiler feed lines or overhead condensers). A mismatch can cause cavitation or insufficient vacuum.
- Key detail: Account for head loss due to pipe friction—actual usable lift may be lower than the rated value.
-
Ultimate Vacuum (-0.098 MPa / 2 KPa)
- The lowest pressure the pump can achieve, critical for processes like degassing or sublimation.
- Comparison: This range suits most lab applications but may fall short for high-vacuum needs (e.g., electron microscopy).
- Trade-off: Higher vacuum levels often require more power or specialized pumps like rotary vane models.
-
Taps and Air Suction (2 taps, 10 L/min per tap)
- Allows simultaneous connections to multiple apparatuses.
- Buyer’s advantage: Enables shared use in labs, improving cost-efficiency. The built-in check valve prevents backflow, protecting experiments.
- Question to ask: How many users or devices will need vacuum access concurrently?
-
Power and Efficiency (180W, 30–50% efficiency)
- Lower power consumption reduces operating costs, while efficiency impacts long-term energy use.
- Hidden cost factor: A 50% efficient model might have a higher upfront price but save significantly over time.
- Note: Voltage options (110V/220V) ensure compatibility with regional power grids.
-
Design Features
- Oil-free operation: Eliminates contamination risks in sensitive applications (e.g., pharmaceuticals).
- 15L water tank: Balances portability with runtime; smaller tanks need frequent refills.
- Compact size (11 kg): Ideal for space-constrained labs or mobile setups.
-
Typical Applications
- Used in distillation, crystallization, and vacuum filtration across industries like biotech and food processing.
- Why choose this pump?: Its quiet, pollution-free operation suits environments where cleanliness and noise matter (e.g., clinical labs).
-
Efficiency Insights
- Standard 30% efficiency is adequate for intermittent use, but 50% models justify their cost in high-throughput settings.
- Maintenance tip: Regular descaling and impeller checks preserve efficiency by preventing mineral buildup.
Final thought: While this pump excels in versatility and ease of use, always cross-check its parameters against your specific process requirements—especially if dealing with extreme temperatures or corrosive materials. Would a modular system with additional pumps offer better scalability for future needs?
