Protective coating upgrade cuts energy costs and carbon emissions at public swimming facility
A public swimming facility in the North West of England has significantly reduced its energy consumption and carbon emissions after upgrading its circulation pumps using LOCTITE ® PC 7255, a ceramic-filled epoxy protective coating developed to protect metal surfaces from corrosion, erosion and chemical attack in demanding operating environments.
The facility, operated by a local authority, relies on multiple high-capacity pumps to circulate chlorinated water across its swimming pools. These pumps operate continuously and are critical to maintaining water quality and hygiene standards. Over time, exposure to aggressive chemicals combined with sustained flow rates had led to internal surface degradation within the pump casings. This wear increased internal turbulence, reduced hydraulic efficiency and placed additional strain on the equipment.
As a result, more energy was required to maintain the required flow rates, driving up operating costs and increasing the facility’ s carbon footprint. The degradation also raised concerns around longterm reliability, with the risk of unplanned maintenance and downtime becoming increasingly difficult to manage. With budgets under pressure and sustainability targets becoming more stringent, the authority sought a solution that could restore pump performance without the cost and disruption associated with full equipment replacement.
Rather than replacing the pumps, the decision was taken to refurbish and protect the existing assets using LOCTITE ® PC 7255. The ceramicfilled epoxy coating was applied to the internal metal surfaces of the pump casings during planned maintenance, allowing the work to be carried out with minimal disruption to pool operations. Once cured, the coating restored a smooth internal surface profile while providing long-term protection against further corrosion and chemical attack.
While this project focused on swimming pool circulation pumps, the same protective coating technology is widely used across industrial maintenance environments where efficiency losses are caused by surface wear.
