The tank capacity of a water circulating vacuum pump typically ranges between 15 to 50 liters, depending on the specific model and configuration. This capacity directly impacts the pump's operational efficiency and maintenance frequency, making it a crucial consideration for purchasers who need to balance performance with practical workspace constraints.
Key Points Explained:
-
Standard Tank Capacities
- 15-liter models: Common in compact units (e.g., 385mm width × 280mm depth × 420mm height), ideal for labs with limited space. These weigh ~11 kg and support processes like reduced pressure filtration.
- 50-liter models: Suited for high-volume applications such as continuous evaporation or large-scale distillation. The larger reservoir reduces water replacement frequency but requires more floor space.
-
Why Capacity Matters for Buyers
- Process duration: A 15L tank may need refilling every 4-6 hours during intensive use (80 L/min flow rate), while 50L extends uptime. Consider: How often can your team monitor water levels?
- Maintenance trade-offs: Larger tanks decrease water changes but increase initial costs and footprint. Smaller units offer portability but demand more frequent attention.
-
Technical Context
- The tank supplies water for creating vacuum via fluid ejection (achieving -0.098 MPa). Capacity affects stability during prolonged processes like crystallization.
- Safety note: All models include check valves to prevent backflow, but larger tanks may need additional overflow protection.
-
Performance Correlation
- Vacuum degree (max -0.098 MPa) isn’t directly tied to tank size, but smaller tanks risk performance drops if water levels aren’t maintained. For 24/7 operations, 50L models are preferable.
-
Decision Factors
- Space vs. convenience: A 15L pump fits benchtops; 50L requires dedicated floor space.
- Process requirements: Batch vs. continuous workflows dictate needed capacity. Example: A 15L unit suffices for intermittent sublimation, while distillation favors larger tanks.
Summary Table:
| Tank Capacity | Best For | Maintenance Frequency | Space Requirements |
|---|---|---|---|
| 15L | Compact labs, intermittent use | Every 4-6 hours | Benchtop |
| 50L | High-volume, continuous use | Less frequent | Dedicated floor space |
