Pump Repair - Thermal Spray Coating


Pumps and plungers are an integral part of industrial fluid handling lines and any fault in them can automatically translate into a production outage. Pump components are also more susceptible to corrosion and wear since they bear considerable abrasion.

A&A’s coatings are capable of restoring these worn and corroded areas to original specification sizes while also offering value added properties such as wear and corrosion resistance.

Coating and Spraying Services Offered for the Pump Repair Industry

A pump can be a rotating, reciprocating, or even a diaphragm piece of equipment. Pumps are designed to move material generally as a fluid. This can be a liquid, a gas or even a solid that can be transported. Pumps also move water, chemicals and even high viscose materials such as hot asphalt. A big enough pump can move almost anything. While moving these products, pumps will face wear and corrosion problems. Thermal spray coatings can be engineered to improve the performance of pumps and their components. In order to boost pump and component performance, A&A Coatings supports the following parts and applications:

  • Impeller and Pump Casings

When corrosion and wear resistant coatings are sprayed on impellers, covers, casings and face plates, a remarkable extension in life of the components is noted. Materials such as chromium oxide ceramic, tungsten carbide, chromium carbide and others are used to achieve this solution.

  • Pump Shafts

Worn bearing areas and seal areas can be coated, ground and/or machined back to original print dimension. If a hard coating material such as ceramic or carbide is used for these repairs the shafts will last significantly longer than they did originally in an uncoated state.

  • Plungers

Areas of Pump Plungers which are susceptible to wear and corrosion are coated with corrosion and wear resistant like tungsten carbide and ceramics in order to provide protection and extend service life.
