HAYLEY DEXIS 247 was recently entrusted with a significant project by a major UK water utility, involving the repair and upgrade of two large river intake submersible pumps, each weighing approximately 4 tonnes. This undertaking not only showcased our expertise in pump refurbishment but also provided an opportunity to implement efficiency-enhancing upgrades.
Comprehensive Overhaul and Upgrades
Upon arrival, the pumps underwent a detailed strip and inspection process to assess their condition. Following the inspection, the following actions were taken:
- General Overhaul
A full refurbishment was carried out to restore the pumps to optimal working condition, addressing wear and tear accumulated during operation. - Mechanical Seal Upgrade
The mechanical seal arrangement was upgraded to improve the pumps’ reliability and reduce the risk of future failures. - Efficiency Coating Application
To enhance performance, Belzona 1341 efficiency coating was applied to all internal passageways. This specialized coating not only protects the pumps from corrosion but also reduces energy consumption by improving hydraulic efficiency.
All Work Conducted In-House
Every aspect of the refurbishment, from disassembly and repair to upgrades and final testing, was conducted at HAYLEY 24/7 DEXIS facilities. This streamlined approach ensured quality control at every stage of the process, delivering a reliable and efficient solution for the client.
By combining expert repairs with performance-enhancing upgrades, Hayley 247 has helped this UK water utility improve the reliability and energy efficiency of its critical river intake pumps, ensuring they are prepared to meet the demands of their essential role.
