Vacuubrand's ATEX series of chemistry diaphragm pumps, available from John Morris Scientific, are suited for use in potentially explosive atmospheres.
Many solvents are flammable and have a high vapour pressure; therefore they can form an explosive mixture when mixed with air.
Due to their high chemical resistance, oil-free operation, and hermitical separation of pumping chamber and motor, Vacuubrand's chemistry diaphragm pumps offer good features for avoiding ignition sources.
Vacuubrand's ATEX series of chemistry diaphragm pumps have precisely-guided planar diaphragms for unmatched diaphragm life and performance.
Typical applications include vacuum generation in large-scale rotary evaporators, chemical reactors, cabinet dryers with solvents as well as all applications with large quantities of flammable solvents.
Vacuubrand ATEX pumps feature: flame-proof motor with integrated, self-locking overload and excess temperature protection for direct 230V/50Hz single-phase power supply; diaphragm pump heads are made of antistatic, reinforced fluorinated plastic compounds with metallic core; separate inert gas connection included; overpressure safety relief at outlet internally and at outlet; and safety dual diaphragm technology with inert gas purge option.
