The circulating water vacuum pump can achieve a maximum pressure of 0.02 MPa (20 kPa) or an ultimate vacuum of -0.098 MPa (2 kPa), depending on the specific model and configuration. This makes it suitable for laboratory applications requiring moderate vacuum levels, such as evaporation, distillation, and filtration. The pump's performance is influenced by factors like flow rate, lift height, and operational efficiency, ensuring reliable negative pressure conditions without oil contamination or excessive noise.
Key Points Explained:
-
Maximum Pressure & Vacuum Levels
- The circulating water vacuum pump can reach a maximum pressure of 0.02 MPa (20 kPa) under standard conditions.
- For vacuum performance, the ultimate vacuum ranges from 2000–4000 Pa (0.02–0.04 MPa) in basic configurations.
- When equipped with a series atmospheric ejector, the vacuum can improve to 270–670 Pa (0.0027–0.0067 MPa).
- Some models specify a maximum vacuum capacity of -0.098 MPa (2 kPa), which is critical for applications like pressure-reduced filtration or drying.
Why this matters for purchasers:
- Higher vacuum levels (lower pressure) expand the pump’s usability in sensitive processes like sublimation or crystallization.
- If your workflow demands deeper vacuum conditions, verify whether the pump supports ejector attachments or additional stages.
-
Performance Parameters Affecting Pressure
- Flow rate (80 L/min): Ensures consistent water circulation, maintaining stable vacuum levels.
- Lift height (10 meters): Must align with system requirements to avoid inefficiencies.
- Safety features: A built-in check valve prevents backflow, protecting the vacuum integrity.
Reflective question:
- Have you calculated the total water supply needs (including auxiliary processes) to match the pump’s flow rate?
-
Operational Advantages
- Oil-free and pollution-free: Ideal for clean labs or environments where contamination risks must be minimized.
- Low noise and portability: Weighs only 11 kg, making it easy to relocate for flexible lab setups.
-
Applications Supported
- The pump’s pressure range suits evaporation, distillation, and pressure-reduced filtration.
- Its ability to sustain -0.098 MPa makes it viable for drying and sublimation where stronger vacuums aren’t mandatory.
Purchaser tip:
- If your processes require pressures below 270 Pa, consider whether a hybrid system (e.g., with an ejector) or a different pump type (e.g., rotary vane) would be more cost-effective long-term.
-
Selection Criteria for Optimal Performance
- Flow rate: Match it to your lab’s peak demand, including simultaneous processes.
- Power efficiency: Account for motor losses to avoid underperformance during extended runs.
- Lift height: Ensure compatibility with your setup’s vertical requirements to maintain consistent pressure.
Final note:
While the pump’s maximum pressure is fixed, its real-world effectiveness hinges on proper sizing and maintenance—factors directly tied to your operational workflow and budget.
