Pumps are the Right Angle for Maintenance at Minworth

Within a very confined bunded area at Severn Trent Water’s Minworth Sewage Treatment Works, the upright design of Borger’s recently installed rotary lobe pumps has significantly reduced maintenance costs and downtime.

Working with the global engineering, construction and management organisation MWH Treatment, Borger’s Maintenance-In-Place (MIP) pumps have replaced progressive cavity units that had to be completely removed to be repaired or serviced.

Installed with angled (helical bevel) direct drive gearboxes (rather than belt drives) to allow installation, the energy-efficient 5.5kW PL200 Borger pumps can have all of their wear parts replaced in situ by the maintenance team, without dismantling any pipe or drive systems.

This new order for Borger follows the success of its previous rotary lobe installation at Minworth where its pumps also reduced maintenance requirements in a difficult belt thickener sludge discharge application. The jetting out of fat has been reduced from around every three weeks (when progressive cavity pumps were in operation) to intervals of just every four months by using Borger’s rotary lobe pumps.
