Börger to supply rotary lobe pumps to Northumbrian Water wastewater facility

Following a six-month trial at Howdon Sewage Treatment Works in the UK, Northumbrian Water is set to replace a total of four pumps with FL776 rotary lobe units made by Börger.

Initially, a Börger pump with optimum rotors was put to work in the heavy rag application, transferring sludge from a holding tank to an AD plant.

Colin Davison, mechanical maintenance team leader at Northumbrian Water, said: “We wanted to improve this part of our process with a pump that would perform with suitable effectiveness, but also be far more reliable and easier to service than what we were using”.

 “Over a sustained six-month period, the Borger FL776 proved conclusively that it is more than capable of handling this tough application, with the bonus that its maintenance-in-place design makes it much easier and far less time-consuming to service than other pumps,” he continued.

To help reduce costs for Northumbrian Water, Borger will be reusing the 30kW drives from the original pumps.
