Identify a Problem
Visual clues for replacement of existing pumps with ChemSafe:
• Corroded pump exterior
• Leaks around the manifolds
• Discoloration of the floor caused by severely leaking pump
• Worn internal fluid bowls
• Enclosed chemical room
Applications
Pickling Baths
Surface treatment used to remove impurities, such as inorganic contaminants, stains, rust or scale that can discolor the steel
Silicone Carbide Slurries
Used in construction, ceramics, paper and explosives industries, among many others
Electroplating
Deposits a layer of a material on an object to improve wear resistance, lubricity or corrosion protection
Printing Inks
Writing and printing inks are made with a wide variety of components, many of which can be abrasive
Ceramic Finishing
Method of finishing that cleans, deburrs and polishes treated surface - abrasive ceramic media is used during the finishing process
Lime Slurry
Industrial, municipal and environmental applications, such as metals precipitation, odor control, sludge stabilization, lime softening and pH adjustment
