Selecting best laboratory vacuum pump
What makes the best vacuum pump ? Is it one with the strongest vacuum level ? No, to make the correct selection, you need to consider several factors (laboratory application, pump type, pump speed & chemical resistance). We are glad to offer Edwards Vacuum’s range of vacuum pumps in Singapore for that.
The determining factor that should guide your choice is desired vacuum level. There are several types of vacuum: a rough or low vacuum, a high vacuum and an ultrahigh vacuum.
| Vacuum type | Maximum pressure (in mbars) | Minimum pressure (in mbars) | Molecules per cm³ |
| Rough vacuum | 1 | 10-3 | 1016 – 1013 |
| High vacuum | 10-3 | 10-7 | 1013 – 109 |
| Ultrahigh vacuum | 10-7 | 10-12 | 109 – 104 |
Pump Characteristics
- Pump’s flow rate: the flow rate is related to the draining time of the machine. It is therefore necessary to evaluate the capacity of the pump to produce both the required pumping speed and mass flow rate according to the process requirements.
- Chemical compatibility: it is necessary to consider the compatibility of the gases used in your application by analyzing all possible problems that the device may encounter.
- Lubrication: it is essential to ask yourself whether or not it is necessary to lubricate the pump. A lubricated one has greater efficiency and resistance. It does however require very regular maintenance.
- Maintenance and Cost : based on the criteria listed above, it will then be necessary to analyze the frequency of maintenance cycles. This will determine the overall cost of your installation, which must take into account the purchase price as well as the operating and maintenance costs.
Based on the above, we can help Singapore customers to choose from below vacuum pumps from Edwards Vacuum.
