Pump Rebuilds and Maintenance

Put our experience to use and allow us to be your BWCP Solution Provider

AVI, has been repairing Boiler Water Circulation Pumps for our dedicated customers, at various power stations around the world, for over 25 years. We know your General Electric, Hayward Tyler, Ingersoll Rand, KSB and Westinghouse pumps, inside and out. With our years of experience, we have developed a detailed inspection process, with upwards of 175+ measurements, to verify the integrity of each component. Identifying the problem is the first step of the process as we strive to bring exceptional life, service, and reliability, to your pump.


Having all of the BWCP components be concentric to each other is important which helps to reduce unbalanced magnetic pull. It is our goal to ensure that the balanced rotating assembly and all of its parts are centrally located, to provide optimum efficiency.

We provide a full set of alignment checks...

As many of these pumps approach 50 years old, new problems are surfacing. A major problem involves the alignment of the rotating assembly within the pressure vessel and the pump bowl. We now include in our disassembly and inspection a full set of alignment checks to show the relative position of the rotor pack and impeller.

Quality Assurance at every step...      

Our Quality Assurance procedures document your BWCP components throughout our facility, from the moment your pump arrives to departure. Rest assured we can provide an update at any time since we document in real time as it occurs.
