KNF LABOPORT vacuum pump system SR 840 G
The KNF LABOPORT SR 840 G vacuum pump system is ideal for laboratory applications that place high demands on durability and reliability. This extremely compact and modularly expandable system proves its strength particularly in aggressive or corrosive gases and vapors. Thanks to the 100% oil-free delivery, media are transported without distortion and substances are compressed and evacuated very efficiently. Comparisons such as with the [KNF LABOPORT SR 820 G vacuum pump system] show that it is characterized by its durability and ease of maintenance, even in demanding applications.
Performance features and technical details
The robust construction and modern design make this vacuum pump system an excellent choice for laboratories, institutes and industrial applications in the chemical, biotechnology and pharmaceutical sectors. An integrated speed control makes it possible to flexibly adapt the pump operation to different work processes without compromising on reliability or performance. Here are some important key data:
- Delivery rate: 2.04 m³/h (corresponds to approx. 34 l/min at atmospheric pressure)
- Ultimate vacuum: 6 mbar (absolute)
- Nominal voltage: 100-240 V at 50/60 Hz
- Power: 100 W (integrated thermal switch and mains fuse)
- Protection class: IP30
- Main materials: TFM PTFE (pump head), PTFE-coated (diaphragm), FFPM (valves)
- Hose connection: Inlet for hose with ID 8-9.5; outlet for hose with ID 10
In addition to these technical parameters, the SR 840 G impresses with its integrated gas ballast valve, which ensures a high tolerance to steam and condensate. As a result, the delivery rate remains stable even when pumping moist vapors. Another advantage is the three-color status display, which allows the operating status, standby mode or any faults to be identified much more quickly. The sustainable design also scores points for its environmentally friendly properties and low energy consumption.
The compact design (299 x 250 x 274 mm) ensures easy integration into existing systems or laboratory set-ups. With a weight of 13.1 kg, the system is also easy to transport or place on a laboratory bench if required. In particular, the chemical-resistant materials and sophisticated design offer reliable protection against corrosion and chemical attacks.
Typical areas of application
- Filtration and distillation in chemical laboratories: Due to its excellent resistance, the system is ideal for organic solvents such as acetone, methanol or toluene
.
- Vacuum drying of temperature-sensitive samples in biotechnology: The low ultimate vacuum limit is predestined for sensitive applications in which sensitive ingredients must be protected.
- Rotary evaporation in pharmaceuticals and research facilities: The high vapor compatibility prevents premature condensation in the pump.
- Gas transfer in industrial processes: The high-performance diaphragm system enables reliable pumping of corrosive gases with a low probability of failure.
Thanks to its modular design, the system can also be used as a component in complex production lines where several pumps or separators are required. With the separately available accessories, the pump can be flexibly adapted to changing process conditions.
