GRAND TERRACE, CA - Griswold™ Pump Co., a manufacturer of centrifugal pumps, announced that the standard and low-flow models of its 811 Series ANSI Centrifugal Pumps are now ATEX compliant. ATEX is the common name for European Union Directive 94/9/EC, which is the European safety standard for all equipment intended for use in potentially explosive atmospheres. With this certification, Griswold’s 811 ANSI pumps are now available for use in places where explosive atmospheres may arise through the mixture of air and flammable materials such as gases, vapors, mists and dusts. These conditions most commonly exist in chemical plants, refineries, liquid-storage terminals and latex plants.
