SAFETY PRECAUTIONS FOR ATEX PUMPS
WARNING: Proper materials of construction must be chosen for the fluid being pumped. Improper material selection could lead to pump
failure and leakage. This is the responsibility of the end user.
WARNING: ATEX pumps must have a power monitor, flow switch, pressure switch or similar device installed to protect against running
dry, closed discharge valve, major leaks, and possible sources of ignition due to motor bearing failure. Any of these conditions could lead
to a rise in surface temperature of the pump. The device must be set to stop the pump within three seconds of a fault.
WARNING: The pump must be checked for leaks on a regular basis. If leaks are detected, the pump must be repaired or
replaced immediately.
WARNING: The pump must be cleaned on a regular basis to avoid dust buildup greater than 5mm.
TEMPERATURE CLASSIFICATION
Pump temperature is completely dependent on operating conditions. Pump will transfer heat from the piping system, motor, and fluid.
These items must be considered as a system when assessing an ATEX application.
