Cast Iron Column Pump
Ambient Salt Water
Chemcote were brought in to carry out pump refurbishment after catastrophic failure of bearing causing the impeller to wear through the casing of the column pump
Refurbish pump lining to extend service life using glass flake filled coatings, then top coated using RP 500 to improve fluid flow efficiency.
Abrasive blast to AS.1627.4 to class 2.5
Masking and protection of critical tolerances and bush area on flange.
Pit filled to allow smooth transition and prevent coating defects
Sand smooth where necessary & application of RB364 to 1,000µm
Internal & external holiday testing to ensure coating continuity using the required voltage to suit the dry film thickness.
Improved corrosion resistance and fluid flow efficiency through the quality assurance process employed by Chemco.
