ATEX chemistry diaphragm pumps offer all advantages of oil-free chemistry diaphragm pumps. Typical applications are rotary evaporators and drying ovens with potentially explosive atmospheres. The ATEX approval includes the interior of the pump (in contact with pumped gases) as well as the surrounding area of the pump.

• Outstanding chemical resistance and superior vapor tolerance
• Mainly made of antistatic materials
• Flame proof motor with integrated, self-locking overload and excess temperature protection for direct 230V / 50Hz single phase power supply
• Overpressure safety relief valves internally and at outlet
• With separate gas ballast connection part for use of inert gas
• Safety diaphragm technology with option for inert gas purge and detection of diaphragm breakage

ATEX compliance:
Pump chamber (pumped gases): II 2G IIC T3 X
Exterior space (pump environment): II 2G IIB T4 X (with inert gas purging) / II 3G IIB T4 X (without inert gas purging)

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)

Measures and displays vacuum pressure both graphically and digitally from 1100 to 1 mbar. Controlling the pressure can be done in real-time. The durable, chemically resistant sensor built into the VCpro 601 vacuum controller is a ceramic thick film hybrid. The sensor reading is gas independent and gives an absolute pressure.

• Precise vacuum control with timed ramp capability
• Fully programmable modes to allow run repeatability
• Intuitive ICON-navigation of control screens
• Connectivity through LAN and RS232
• Built-in function for self-cleaning of diaphragm pump
• Security levels for administrators and users
• Log files on all pump activities for easy traceability
• High-Res display with dark and light screen modes
• Digital and analogue vacuum pressure display
• Automatic destillation control
• Can be used with diaphragm or piston pumps from any manufacturer

The compact pumps feature a control knob for manual adjustments of the flow rate, making them well suited to a wide variety of applications, e.g. rotary evaporation, distillation, gel drying, degassing as well as the use with vacuum ovens and vacuum concentrators. Due to the manual rotational speed control, the pumps are quiet, very energy efficient, and can be optimally adjusted in accordance with the application.

• Easy-to-clean surface
• Adjustable in flow rate due to manual rotational speed control
• Combination of PTFE pump head and PTFE-coated diaphragm makes the pump ideal for extremely aggressive/corrosive gases and vapors
• High level of compatibility with vapor and condensation
• Integrated gas ballast valve
• 3-color status display: In operation / Stand-by / Error
• ATEX-compliant in accordance with II 2/-G IIB+H2 T3 internal atmpsphere only
