Fluid Temperature Range
Approvals
ATEX T-code rating is dependent on
the temperature of the fluid being
pumped. Fluid temperature is limited
by the materials of the pump interior
wetted parts. See Fluid Temperature
Range for the maximum fluid
operating temperature for your specific
pump model.
Except for 3-A pumps, all
pumps are approved to:
II 2 GD
Ex h IIA T6...T3 Gb
Ex h IIIB T160°C Db
Diaphragm materials coded
EO, PO, or PS combined with
flapper or PT ball checks
comply with:
EC 1935/2004
Diaphragm materials coded EO
or PS combined with flapper or
PT ball checks comply with:
Class VI
All models are approved to:
All fluid contact materials are FDA compliant and meet the United States
Code of Federal Regulations (CFR)
NOTICE
Temperature limits are based on mechanical stress only. Certain chemicals will further limit the
fluid temperature range. Stay within the temperature range of the most-restricted wetted compo-
nent. Operating at a fluid temperature that is too high or too low for the components of your pump
may cause equipment damage.
