Cat Pumps UK has developed and
tested a range of high pressure triplex
pumps for use in Explosive
Atmospheres. The pumps
require very few
modifications to make
them suitable for use in
ATEX areas. Generally,
minimising the risk of sparks
caused by a build up of static
electricity and strengthening a few
parts to protect against accidental
damage is all that is needed. They do
not get hot enough in normal use to
ignite most vapours.

Cat Pumps offer bareshaft pumps
for use in Zone 2 and Zone 1 areas.

These are designated II 2G cb IIB T4
for use in most flammable gas
environments except Zone 0 and are
available for applications of
1 to 300L/min and for
pressures to 700 bar.

The company
can build its pumps
into motorised
packages including
ATEX motors to the
required configuration,
together with guards, transmissions
and other components.
