FK ATEX Submersible pumps

FK is the new DAB professional submersible wastewater pumps.
Thanks to their construction, FK can guarantee reliability, efficiency and ease of maintenance, which are important values for installers and maintainers.
Suitable for the transfer of wastewater in public buildings, industries, subways and parking lots, the FK range has been designed for pumping wastewater with varying solids contents: from the drainage and surface water, up to residential wastewater; from wastewater with high fiber content up to industrial wastewater.

APPLICATIONS
Design for the pumping of wastewater and sewage from buildings and sites in private, commercial, industrial areas in accordance with European
Standard EN 12050-1.
Available in Ex version for use in potentially explosive atmosphere (ATEX certifications: II2G Ex db k IIB T4 or IECEx: Ex db IIB T4 Gb)
PUMP CONSTRUCTION
