OPERATIONINEXPLOSION‐PROOFAREASANDFORFLAMMABLELIQUIDS(REG.‐NO.PTB:03ATEXD004)
For flammable liquids as well as for applications in explosion‐proof areas, only pumps
with housingsandfittings in conductiveplastic materialsmaybe used.AODDpumps of
theE‐Serieswiththehousingcodes
F(PEconductive)andU(PTFEconductive)meetthis
requirement. The pump has to be grounded. A connection to ground the pump is
included in the center housing [4]. All other housing parts are connected to the center
housing;thereforeitisnotnecessarytogroundsingleparts.
ALMATECE‐Series
pumpsmadeofelectricallyconductivePE/PTFEaresuitabletobeused
in explosion areas of the category 2 and 3, atmosphere G/D, which are liable to the
94/9/EG. Conductive diaphragms (liquid side) are applicable without restrictions for
transferringliquidsofanyexplosion‐group.
When using non‐conductive diaphragm materials,the
following exemplary protection measures haveto be
respected:
‐Thepumpisalwaysusedforthetransferofexclusivelyfluidswhichareconductiveorsolubleinwateror
‐Dry‐runningisavoidedbyactionstepswithinthefacilityand/oritscontrolor
‐ The system is inertisated in case of dry
running by nitrogen, water, carbon dioxide etc. when the fluid
transferends.
Piping systems and product connections have to be grounded separately. To avoid ignition hazards the
formation of dust deposits on the pumps must be prevented. In explosion proof areas repair working only
aftercarefulinspectionofthepracticability
