Belzona offers a solution for pump lining which has proven efficiency enhancement in the pump post application.
In 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 their pumps and the coating of their pumps to increase efficiency. Due to their great experience and expertise in the field, Belzona Authorised Coating Centre WGM Engineering (Glasgow) won the tender.
WGM Engineering removed, overhauled and installed 2 of the 48″ CW circulating pumps, each weighing over 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 new state of the art service centre in Glasgow and underwent a major refurbishment programme. Belzona 1111 (Super Metal) was specified for the rebuild repairs to the damaged diffuser vanes, whilst Belzona 1311 (Ceramic R- Metal) was used to repair the areas of high erosion-corrosion
pitting. 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. The main pump exteriors were coated with two coats of Belzona 5811 (Immersion Grade) to give long term immersion protection.
