Chemistry-design diaphram pump for distillation system.

• Simple entry of the desired vacuum level and differential pressure
• Precise reproducibility of set values
• Facility to interrupt pumping program at any point
• The chemvak system with vacuum controller automatically vents to atmosphere when switched off (this prolongs the operating life of the pump)
• Easy venting of the system at a touch of the key pad
• One touch resetting from controlled pumping to maximum vacuum
• In the event of power failure the last entered values are retained
• Continuous operation work mode
• 50 dB noise

The vacuum pump is gas-tight, 100% oil-free, maintenance-free and quiet. All parts of the pump head in contact with gases being pumped are resistant against aggressive substances (materials: PTFE, FFKM, PVDF). New valve system is very tolerant of water vapour and condensates. Illuminated switch on pump. Over-load protection by means of thermal switch. Compact design with space saving dimensions.
