WILO EMU”s CERAM coatings combine ceramics and polymers to protect submersible pumps and impellers from corrosion in harsh application environments. CERAM was developed in 1997 by WILO EMU and is available in four thicknesses, C0, C1,C2, and C3. All CERAM coatings are nonporous and have an adhesion level of 15 Newtons per square-inch. In addition to corrosion prevention, CERAM offers a high level of efficiency due to a reduction in surface roughness and, because it is solvent-free, CERAM is environmentally friendly.
