Dubai Electricity & Water Authority (DEWA) is replacing its industrial pump bearings with Thordon water lubricated bearing solutions.
This follows the installation of the Canadian company’s pioneering technology to desalination plants across the United Arab Emirates.
Ocean Power International (OPI), Thordon Bearings’ Dubai-based distributor, supplied ThorPlas-Blue and SXL bearings for installation to 20 butterfly valves and 7 brine recirculation and vertical pumps.
DEWA has been systematically replacing its traditional bearings with Thordon products at facilities across Dubai.
OPI managing director Rafid Qureshi said: “After hearing about the issues that DEWA was having with the original bearings, we proposed a solution that included ThorPlas-Blue. After checking load calculations and ensuring operating pressures did not exceed the bearing material’s 45 MPa (6,527 psi) tolerance, we machined and fitted the Thordon bushings.
“Since that first installation, we have replaced pump and valve bearings at several power generation and desalination plants across Dubai.”
In 2019, OPI and Thordon completed bearing retrofits at the OPI workshop for a de-mineralisation pit pump after fabric lined metal bearings had worn out. And in May last year, 20 vertical pumps and six brine recirculation pump isolation valves at the OPI workshop were retrofitted with the Thordon polymer material.
The ThorPlas-Blue bearing can be used in all types of industrial pump applications and is an ideal replacement for bronze and other non-metallic bearings. It is available in a wide range of sizes and is easily machined to the dimensions required.
