Part Number: 696930Product Details
Overview
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 pumps are mainly made of antistatic materials. Included in delivery is a separate gas ballast connection part for use of inert gas.
Features
• Outstanding chemical resistance and superior vapor tolerance
• Flame proof motor with integrated, self-locking overload and excess temperature protection for direct 230V / 50Hz single phase power supply
• No technically demanding over current protection by customer necessary
• Overpressure safety relief valves internally and at outlet
• Safety diaphragm technology with option for inert gas purge and detection of diaphragm breakage
