Bedford STW cuts pump maintenance by 'around 90%'
28 Apr 2011
Bedford, UK – Bedford sewage treatment works (STW) was experiencing recurrent ragging problems with one of its pumps for transferring primary sludge from settlement tanks. The unit was positioned in a pit below ground level makes maintenance even more difficult.
By replacing the progressive cavity pump with a seepex alternative, the STW was able to resolve maintenance issues within 30 minutes, instead of the “half a day” it used to take, said seepex.
The efficiency was down to the pump maker’s ’smart conveying’ design, which allows maintenance work to be performed in situ in a few easy steps without dismantling internal joints or removing pipework. This, claims seepex, enables manual intervention times to be reduced by up to 90%.
The conveying technology “is so much easier to work on than other technologies,” said Mark Cooper, operations manager at Bedford STW – commenting in a 20 April seepex press release.
According to seepex, its ’smart’ technology is particularly useful when space is limited as maintenance can be carried out in situ. The savings, it adds, can apply similarly to new installations and to retrofits.
