INDUSTRIAL distribution company Brammer claims Scottish Water is benefiting from improved operation of its three sludge pumps after installation of WEG W21 AC motors and CFW-09 drives.
According to Brammer, WEG’s motors and drives have replaced existing DC pump drive motors which were used on Whitehead and Poole piston ram pumps. The pumps are used to transfer sludge from Scottish Water’s Laighpark waste water treatment plant to Shieldhall waste water treatment plant.
Brammer says the DC pump drive motors were beginning to cause problems for Scottish Water, including repeated failures and limited availability of spare parts.
The new WEG W21 AC motors, CFW-09 drives and control gear were supplied to a local panel builder, which were then built into control cubicles and installed on site. An engineer from WEG is said to have visited the Laighpark site to assist in the commissioning of the project which was completed in a day.
Brammer says it has a framework agreement with Scottish Water, where it actively works to provide cost effective, reliable and suitable products including gearboxes, motors, inverters, power transmission and bearing seals.
Walter Bryce of Brammer says Scottish Water was looking for a solution which delivered the same flexibility they previously had to control the pumps.
“However, these benefits had to be delivered in a package that offered the best competitive price and the longest possible warranty. Following consultations with Tony Leslie and David Doig, both Technical Support Advisors, we were able to deliver all these benefits with a matched motor and inverter drive package from WEG,” Mr Bryce said.
