The Situation
The customer, a UK water supplier, requested a site visit from a member of the specialist HAYLEY DEXIS | Drives team. The aim of the visit would be to investigate the various problems that they were having with motors and gearboxes and to propose a solution. On-site were two obsolete Varatio drives, one very close to suffering a total failure and the other at the outer limit of its expected service life.
The Solution
During the walkaround of the site, it was noticeable that the obsolete drive systems attached to the sewage treatment tanks were no longer capable of operating as the application required. Action needed to be taken swiftly, as one tank at the site was not functioning and the drive on the other tank was struggling to operate effectively. This presented a flood risk, which carried with it the threat of considerable cleaning costs. HAYLEY DEXIS offered a Siemens inline geared motor as a solution, with dimensions mirroring the original units to allow for a straightforward swap-out. The new units were built from stock parts, available through the HAYLEY DEXIS branch network, and delivered to site within three days of the initial site visit.
"THE NEW ASSETS ARE MORE ENERGY EFFICIENT AND RELIABLE."
The Result
The Siemens inline geared motors used to replace the obsolete Varatio units have a standard European footprint, and its components are readily available should any issues arise with these assets in future. The customer can now be sure that replacement stock can be sourced locally and fit with ease, minimising both future cost and downtime suffered. The new assets are also more energy-efficient and reliable, enabling the customer to enjoy long-term cost-savings in terms of energy and maintenance. This has a knock-on effect of also reducing the carbon footprint of the operation.
