ATEX Pumps 系列

ATEX Compliant Pumps from Cat Pumps

Cat Pumps offers a complete line of pumps that meet the ATEX 2 directive for pumping applications located in potentially explosive atmospheres. Pump compliance with the ATEX directives is common in industries such as petrochemical, chemical, oil & gas, and bio-fuels.

Under the appropriate ATEX directive, equipment is designated by group, category and zone. Cat Pumps has been certified as ATEX 2 compliant, which also covers the ATEX 3 requirements.

All Cat Pump models (excluding gearbox driven) in the following frame sizes are compliant with the ATEX directive for Group 2, Category 2 and Zones 1 and 2 (Group 2 includes Zone G) :

Equipment Designations

• Group 2 identifies equipment used in hazardous explosive atmospheres other than mining.

• Category 2 defines the level of protection required. Equipment in this category is intended for use in areas in which explosive atmospheres caused by gases, vapors, mists, or air/dust mixtures are likely to occur.

• Category 3 is equipment intended for use in areas in which explosive atmospheres caused by gases, vapors, mists or air/dust mixtures are unlikely to occur or, if they do occur, are likely to do so only infrequently and for a short period only.

• Zone 1 is a place in which an explosive atmosphere consisting of a mixture with air of dangerous substances in the form of gas, vapor or mist is likely to occur in normal operation occasionally.

• Zone 2 is an area in which an explosive mixture is not likely to occur in normal operation and if it occurs it will exist only for a short time
