Custom basket strainer for highly corrosive phosphoric acid service
This basket strainer was engineered for the filtration of phosphoric acid above 85 wt%, where chemical resistance, coating integrity and dependable mechanical performance are essential.
Internal protection
The process-contact surfaces are protected with a PFA Ultra+ Black coating. This chemically resistant, non-porous lining is applied internally, including the fl**ge faces and edges. The basket is coated on all sides as far as technically feasible.
Non-electrically conductive
FDA-conforming
Nominal layer thickness: approximately 0.5 mm
Local thicknesses of up to approximately 2.0 mm may occur and are considered in the component tolerances and fitting
External protection
All external surfaces that are free from PFA lining receive a durable coating system consisting of:
2-component epoxy primer
2-component polyurethane topcoat
Silky-gloss finish
Colour: RAL 7005 Mouse Grey
Total dry-film thickness: approximately 120 µm
