The KNF LABOPORT SR 820 G vacuum pump system is a reliable and chemically resistant laboratory diaphragm pump that is ideal for demanding laboratory applications. Whether evacuating gases or handling aggressive vapors, the system offers excellent durability and performance thanks to its sophisticated design and high-quality materials. Anyone looking for a robust and modularly expandable vacuum pump system will find an efficient solution here. Comparisons with the [KNF LABOPORT SR 832 G vacuum pump system] show that other models from the same series also have similar performance features, but this model scores particularly well in changing operating conditions thanks to its well-adapted conveying and ultimate vacuum range.
Performance features and design
This vacuum pump system is designed to operate 100% oil-free. This contributes directly to the purity of the pumped gases and avoids any contamination, which can sometimes occur with oil-lubricated systems. The housing and all wetted parts are designed for high chemical resistance, which is crucial in laboratory environments with aggressive media. Thanks to the integrated gas ballast valve, steam and condensate compatibility is also improved.
In addition to the high chemical resistance, the system impresses with its integrated speed control. This allows the delivery rate and ultimate vacuum to be quickly adapted to the respective requirements without having to risk major wear or reduced service life. The 3-color status display enables convenient monitoring of the operating status and ensures greater safety in everyday laboratory work. If you are looking for an even more compact or simpler solution, you can also consider products such as the [KNF LABOPORT vacuum pump system SR 810 G], whereby the device described here is designed especially for laboratories with regular and intensive applications.
An overview of the key technical data:
- Delivery rate: 1.2 m³/h (20 l/min)
- Ultimate vacuum: 6 mbar absolute
- Nominal voltage: 100-240 V (50/60 Hz)
- Power: 60 W
- Protection class: IP30
- Pump head: TFM PTFE
- Dimensions (W × H × D): 282 × 234 × 260 mm
- Weight: 10.7 kg
The pump can operate at both 100 V and 240 V and therefore covers a wide range of international applications. The PTFE-coated diaphragm and FFPM valves underline its resistance to aggressive and corrosive media. The system also offers a correspondingly high level of protection against condensate or any vapors.
A special feature is the option to expand the vacuum pump system on a modular basis. Two separators have been integrated on the suction and pressure sides to trap impurities and increase the system's longevity. The start-up against the ultimate vacuum supports the pump start in demanding processes. The environmentally friendly operation, completely without oil, means there are no oil vapor emissions.Certifications and standards
The device complies with current safety and quality standards for use in laboratory environments. Typically, chemical-resistant laboratory pumps such as these are manufactured in accordance with the relevant criteria of the CE standard. This ensures that applicable safety regulations are complied with. For many laboratories, it is essential that the pumps meet high quality standards and operate stably in order to minimize downtime.
Concrete application examples
This vacuum pump system has numerous applications in laboratory practice:
- Use in rotary evaporators to evaporate solvents such as acetone, methanol or dichloromethane.
- Vacuum filtration in chemical and biochemical laboratories, for example when separating solids and liquids in filter units.
- Evacuation of reaction vessels for sensitive chemical reactions that need to be controlled under reduced pressure conditions.
- Distillation of corrosive substances where the pump material must reliably withstand aggressive vapors.
FAQs
How often should the vacuum pump system be serviced?
As a rule, comparatively little maintenance is required as it is an oil-free diaphragm pump. However, it is recommended that the diaphragm and valves are checked at regular intervals to ensure consistently high performance.
Is the system suitable for aggressive chemicals such as concentrated acids?
Yes, thanks to the TFM PTFE pump head, PTFE-coated diaphragm and FFPM valves, the system is expressly designed to handle aggressive and corrosive gases and vapors.
Can the speed control individually control the flow rate?
Absolutely. The integrated speed control allows flexible adjustment so that both less noise development and finely graduated control of the vacuum level can be achieved if required.
What exactly does the 3-color status display mean?
The 3-color status indicator shows the current operating status. Green usually indicates normal operation, yellow indicates standby and red indicates a fault. This allows you to see from a distance whether the system is running smoothly.
Conclusion
This powerful and reliable vacuum pump system offers a convincing blend of chemical resistance, precise speed control and high vapor compatibility. Thanks to its modular design and the possibility of customizable operation, it is a true all-rounder for laboratory applications where purity, process reliability and long operating times are crucial. This ensures stable performance, which is essential in many demanding laboratory processes.
