ATEX PNEUMATIC AUTOPUMP
100% Air-Powered Submersible Pump for Hazardous Area and Remediation Applications
The EIM ELECTRIC CO. LTD ATEX Pneumatic AutoPump is a fully air-powered submersible pump designed for safe, reliable fluid extraction in classified hazardous environments. Available in bottom inlet and top inlet configurations, it delivers maximum effectiveness in wells with diameters as small as 50 mm (2 inches) and is capable of operating at depths of up to 90 metres.
ATEX certified for Zone 0 operation, the pump handles hydrocarbon remediation, solvent cleanup, suspended solids, corrosive fluids, and high viscosity liquids without the need for surface timer-based controllers, bubblers, or in-well sensors. Proven at thousands of remediation sites worldwide, it is the choice of environmental and industrial professionals where reliability and safety in demanding conditions are non-negotiable.
