ATEX Pumps

The ATEX directive requires equipment intended for use in atmospheres evaluated as explosive be designed to contain and minimize the possibility of ignition. This directive applies to new electrical and mechanical equipment supplied for such zones such as ATEX Pumps.

Atex directives define the various zones of an explosive atmosphere and classify zones depending on:

1) Closeness to Area 1 to 3
2) Gas present in an area
3) The maximum surface temperature of heat-generating parts

Although some materials such as GG25 (grey cast iron) may be accepted as complying with ATEX for pumps, it is not recommended for use as grey cast iron can crack easily leading to fluid leakage if exposed to a shock. Grey cast iron can also spark if brushed against the ground when moving into situ. Plastic parts can be used in ATEX environments providing they are carbon-impregnated meaning they become conductive otherwise there is a risk of static build-up and electrical discharge which would ignite any surrounding gases.

North Ridge Pumps regularly supply ATEX pumps for fuels, chemicals and inert liquids used in ATEX areas within 4-8 weeks - view ATEX pumps here.
