ATEX COMPLIANCE
The FTI PFS drum pump has been designed for use in hazardous environments. It meets the requirements set forth by EC directive
94/9/EC. This pump is designed to operate in zone 0 where explosive atmospheres are present. All three components (drum pump
tube, motor and Static Protection Kit) must be properly installed.
TEMPERATURE CLASSIFICATION
The surface temperature of the PFS pump depends upon the temperature of the fluid being pumped. Below is a chart showing the
temperature class that the pump falls in for various fluid temperatures, when used in locations where the ambient air temperature
is no greater than 104°F (40°C). The PFS, when used in hazardous locations, should only be used on products that allow for safe
operation within these classes.
ATEX MOTOR INFORMATION
This symbol appears on labels of motors that are designed for use in hazardous atmospheres. These motors comply with
the applicable standards and specifications and meet the requirements of the guidelines of the EC directive 94/9EC (ATEX
100a). They are intended to be used in zones 1 and 2 where explosive atmospheres are likely to occur.
Complete the following checklist prior to starting installation in a hazardous area. All actions must be completed in accor-
dance with ATEX 100a.
Checklist for installation in hazardous areas:
• Read motor label to check that motor has been designed for use in a hazardous application:
• Hazardous Zone
• Hazardous category
• Equipment group
• Temperature class
• Maximum surface temperatures
• Check the site environment for potentially explosive oils, acids, gases, vapors or radiation
• Check the site to make sure that the motor will be adequately ventilated and that there is no external heat
input. The cooling air may not exceed 104ºF/40ºC.
• Check that the motor is not damaged.
• Maximum motor surface temperature should not exceed 275ºF/135ºC based on ATEX temperature class T4
ambient range +1C° to + 40°C (34°F / 104°F).
