These particular titanium pump components sent in to IRS by a leading chemical manufacturer would normally by regular standards be past the point of repair, except that these components had been manufactured in pure titanium. The costs and availability of replacement components weighed heavily. IRS was asked to evaluate the situation and if possible, put forward a written rebuilding procedure with an estimate of time and costs.
The weld procedure and scope of work submitted by IRS was accepted and the project authorised. All of the impellers and volute casings were completely rebuilt and restored to original manufacture with pure Titanium, as were the shafts. Processing time was far shorter than attempting to source new components and the pumps were returned to service at a fraction of the lead-time and cost of replacement parts.
