Vacuubrand rotary vane pumps encompass one and two stage pumps with throughputs from 2 to 9 m³/h.
Typical rotary vane pump applications include, use as a backing pump for turbomolecular pumps but also serve in diverse chemical laboratory applications.
Features and important characteristics: high water vapour tolerance, vacuum tight pumping mechanism when switched off, high performance gas ballast mechanisms. These increase the overall performance potential of these pumps, the service life of mechanical parts, increase oil-change intervals and reduce maintenance overheads.

The Welch CRVpro pumps are high-performance two-stage vacuum pumps. They impress with their long service life, high reliability and low maintenance requirements. The CRVpro series are the perfect partners for freeze dryers, vacuum concentrators, Schlenklines, glove boxes and vacuum ovens, as well as industrial applications.

• Cool running operation for less oil consumption
• Coated oil case to slow metal corrosion
• Extended oil change intervals for less maintenance costs
• Dual voltage

Piston pumps are a reliable partner for physical applications, notably with aqueous solutions. Being a vacuum pump and compressor, it can be used for a wide variety of applications such as filtration, gas sampling, vacuum drying, desiccation and automation technology. The integrated vacuum and pressure gauges and regulators allow the pressure to be continuously monitored and adjusted. For use with dry or aqueous vapor applications only.

• Oil free
• Easy to clean
• Easy maintenance
• Easy handling and control features
• Robust construction
• Pressure connection with exhaust silencer
• Suction/pressure connection: hose nozzle DN 8 for hose inner diameter 8 mm

The Rotary Vane Vacuum Pump RC 6 has been designed to minimise the adverse effects of condensable and corrosive vapours. Its main components are a two-stage rotary-vane pump and a two-stage chemistry diaphragm for optimised corrosion resistance. The diaphragm pump continuously evacuates the oil reservoir of the rotary-vane pump in order to keep the partial pressures of solvent vapours, oxygen and corrosive gases at a low level and/or below their condensation point. The RC 6 is a low-maintenance pump for freeze-drying and other applications requiring an ultimate vacuum in the 10^-3 mbar range.

Scope of supply: Pump, overload circuit breaker and mains cable (2 m), centering and clamping ring for inlet, particulate filter, operating instructions, oil (bottle of 500 ml)

Fully equipped vacuum controller with capacitive, gas type-independent absolute pressure measurement using an alumina-ceramic diaphragm. While the base unit Vacuum Controller VACUU·SELECT^®still requires a separate vacuum control valve as an accessory, there is the fully equipped Compact controller VACUU·SELECT^®as two-point vacuum regulator with chemical suction line valve.
With connected vacuum valve the VACUU·SELECT^® automatically detects the boiling point during solvent evaporation and switches to two-point control mode. The graphical user interface offers predefined vacuum processes for all common laboratory applications. Applications, such as desired vacuum and other parameters can also be put together and controlled individually.

• Interactive, graphic touch display for easy operation
• Touchscreen display can be operated with safety gloves
• Predefined vacuum processes for reproducible results and time savings in the laboratory
• Fully automatic evaporations at the touch of a button
• Easy-to-use application editor for creating your own processes
• Integrated help function
• Integrated ventilation valve also for inert gas
• Ethernet/USB (Type A) interface
• EX approval: II 3/- G IIC T4 X Internal Atm. Only
