Coating enhances efficiency, product life A power station in Northern Ireland recently sent out a tender for their cooling water pumps to be removed, serviced and returned to use. Looking to minimise costs, while also extending the product's lifecycle was extremely important. Belzona offered a solution for pump lining which has proven efficiency enhancement in the pump post application. The process took eight weeks and came in under budget.

n recent years Belzona has seen pump applications increase dramatically as companies seek to minimise running costs by tackling the issues of reduced efficiency. By way of example a power station in Northern Ireland recently sent out a tender for their cooling water pumps to be removed, serviced and returned to use. Prior to this, Belzona’s local engineer specified Belzona’s solutions to the power station for the repair and rebuild of its pumps and the coating of its pumps to increase efficiency. Belzona Authorised Coating Centre WGM Engineering (Glasgow) won the tender. WGM Engineering removed, overhauled and installed two of the 48” CW circulating pumps, each weighing more than 11 tonnes without the motor, that were failing to deliver sufficient flow to satisfy customer demand. After removal, the pumps were transported to WGM Engineering’s service centre in Glasgow and underwent a major refurbishment programme. Belzona 1111 (Super Metal), is a two component repair composite based on a ceramic steel reinforced polymer system. This was specified for the rebuild repairs to the damaged diffuser vanes, while Belzona 1311 (Ceramic R- Metal) was used to repair the areas of high erosion-corrosion pitting. This product was selected as it can be easily applied by hand to damaged metallic components and once the diffuser vanes were repaired, it protects against erosion-corrosion. Belzona 1341 (Supermetalglide) was specified for the internal coating of fluid flow areas

including the impellors and diffusers. This coating, which is utilised for efficiency enhancement, has shown that an improvement of up to 5% can normally be achieved when coating new pumps. As well as making the equipment more efficient, this product also extends the life of the equipment The main pump exteriors were coated with two coats of Belzona 5811 (Immersion Grade) to give long term immersion protection. Post refurbishment, the pumps were returned to the power station, where they were installed, aligned and commissioned by WGM Engineers. Both pumps were returned to service within an eight-week period and within budget. In addition to its global presence, Belzona is firmly committed to providing local support to service their customers' needs. This commitment can be seen in the partnership between WGM Engineering and Belzona. WGM Engineering has been using Belzona products for 10 years and together the two companies
have provided long term, reliable solutions to a large number of clients. Throughout WGM’s development they have undertaken continuous training in the application of Belzona’s coatings and repair materials in order to conform to Belzona’s high application standards. The skilled workforce, together with the addition of new blasting facilities and a dedicated application room have led to WGM being awarded the coveted Authorised Coating Centre status. Belzona works in partnership with a number of Authorised Coating Centres across the UK, and provide a full turnkey repair service for rotating equipment. This means that each centre is recognised by Belzona Polymerics to provide a specialist service for the rebuilding, long term protection and efficiency enhancement of rotating equipment such as pumps, fans and blowers. www.belzona.co.uk
