The Science Of Precision Coatings

Pumps & Compressors

Key Benefits:

  • Improved hardness and wear resistance
  • Improved flow rates due to low coefficient of friction, 10% improvement observed
  • Corrosion and chemical resistance, Bi-Pro for severe corrosion environments
  • Thin, precise deposits do not affect part tolerances, weight, or balance
  • Anti-galling
  • USDA approved and FDA compliant for use with food applications
  • Extended product life with less downtime for maintenance and repair
  • Able to strip and re-plate indefinitely

For protection against the most common forms of wear including corrosive, abrasive, and erosive wear, consider coating your critical pump, valve and compressor surfaces with a protective Armoloy coating. Pump and compressor components experience extended wear life when coated with the Armoloy family of coatings.  Whether cast iron or stainless steel, clearances are maintained, and repairs can be made to a coated component without compromising the coating’s adhesion to the base metal.

Due to the high lubricity of the Armoloy TDC®, XADC®, and Nyflon® coatings, friction is greatly reduced for improved media flow. In a recent application, material flow was improved by nearly 10% after the TDC® coating was applied to pump rotors, housing, and end caps.

In applications involving severe corrosion, Bi-Protec® is an unparalleled engineering solution. A dual-layer process, Bi-Protec® employs an under-layer of electroless nickel up to .003″ thick, followed by a standard application of .0002″ of Armoloy TDC®.

Armoloy TDC® and XADC® are approved for food contact applications by the USDA, and considered safe for food contact by the FDA. The coatings are able to withstand temperatures in excess of 1200˚ F.

The Armoloy coatings provide longer, uninterrupted life to pump and compressor components, whether the material being conveyed is wet or dry, abrasive or corrosive.

Common applications include:

  • Housings
  • Rotors
  • End Plates
  • Ports
  • Bushings
  • Sleeves/Liners
  • Gears
  • Splines
  • Impellers
  • Elbows
  • Seals

The Armoloy family of coatings are specifically designed to keep machinery and equipment running longer. For increased wear life, reduced friction, protection from corrosion and galling, and many other benefits, Armoloy of Illinois provides a full range of metallic surface coatings to the manufacturing community. High precision is our specialty.

Armoloy provides industry-leading protective metallic coatings that benefit various industries, including food processing/packaging, oil/gas extraction, Aerospace, medical, and nuclear industries, to name a few. Metal surface treatments tailored to these applications must withstand extremely harsh conditions and provide added durability capable of extending the life of components and systems. Our experienced staff can help engineer the right metal finishing solution to your application.

Our proprietary metal surface treatments are fully compliant with the industry's most rigorous requirements and certifications. At less than 170ᵒF, the Armoloy metal finish process is considered a "cold process" that will not distort or anneal coated parts. The Armoloy coatings form a hard protective metallic surface with an absolute bond to the base metal that will not affect part tolerances or balance. This thin, precision coating will improve surface hardness and lubricity while dramatically increasing your coated parts' wear life. Our stringent quality requirements and onsite product testing will ensure your parts meet strict industry standards.

Armoloy offers a variety of coating solutions engineered to solve your coating needs. The Armoloy TDC/XADC coating will not flake, chip or peel from your base material ensuring a safe coating process that is food and medical application safe. Your maintenance and machinery expenses will lessen thanks to the coating's increased wear resistance leading to decreased downtime and replacement costs. Don't settle for traditional metallic plating shortcomings when you can have the Armoloy family of coatings protecting your valuable automated systems and components.
