PUMP COATINGS


SURFACE MODIFICATION SYSTEMS INC. (SMS) provides pump coatings for pumps operating in severe service environments. One of the major benefits of working with SMS is our capability to combine welding, thermal spray, diffusion coatings along with machining and grinding to provide a unique solution to your particular application.

Currently SMS manufactures and coats the following components for major OEM’s

• Wear Rings
• Sleeves
• Bearings
• Shafts
• Casing coatings
• Suction box coatings
• Impeller coatings
• Throat bushings
• Plungers
 

Typical applications for our coatings can be found in mining, catalyst service in refineries, chemical plant service, geothermal plants, boiler feed water applications in power plants.

SMS has developed special coatings for multistage submersible pump stages enabling life extensions of over five times in petroleum production

Continual research has improved the above coating where SMS can now apply coatings of varying thickness to selected areas to increase erosion resistance.

SMS also offers pump repair and improvement. For example in a certain application Hastelloy pumps were being severely degraded by a combination of corrosion and cavitation erosion. SMS developed a special weld repair followed by a two step coating process to enable these pumps to out perform OEM supplied hardware
