Mono of the Glen
2 Oct 2007
Manchester, UK - Severn Trent Water is operating two auto desludge packages from Mono Pumps, at its Great Glen Sewage Treatment Works in Leicestershire. The installations, which have replaced aging double-disc pumps, were part of an equipment overhaul undertaken by project engineering firm Exeeco.
Each package comprises a Mono progressing cavity pump, pipework, valves, control panel, over pressure switch and dry run protection system, all supplied on a skid mounted baseplate and delivered to site. The systems are being used to draw sludge from a primary tank and pump to a holding tank 70 meters away at 1-3 l/s and 3bar pressure.
According to Mono, the units provide lower installation costs, as the package only has to be positioned on a pre-prepared foundation slab, with only suction and delivery pipework connections required and mains feed connection to the panel.
The compact progressing cavity pump, meanwhile, offers a fully sealed drive train to maximise life and minimise downtime and fully adjustable variance in pump speed enables correct sludge consistency to be maintained, claims Mono.
