'Chopper' pumps don't get blocked
Another successful installation of Vaughan 'Chopper' pumps has resulted in a significant reduction in the previous site problems from pump blockages at an Anglian Water Services Pumping Station
The Hartford Road Pump Station in Huntingdon is one of a number of facilities within the Anglian Water Region where raw domestic and industrial effluent is collected and processed, with raw sewage being transferred within a dry-well pumping application Problems arose, when during high flow conditions, the original pumps became blocked with fibrous rag material and other flotsam contained in the sewage streams

The ability for pumps to operate efficiently, even when storm surges and unusually high flows occur, is an essential requirement in many water, waste and effluent treatment applications
'Chopper' Pumps help Southern Water to cut costs
Vaughan Chopper Pumps and mixing systems, supplied by P+M Pumps, have enabled a significant improvement in the throughput of sludge and reduced maintenance at one key Southern Water site
These problems were particularly severe when storm conditions occurred, which led to sewage streams backing-up, causing spillage and flooding.
Blockages were an on-going problem, with around 2 to 4 pump failures a week during extreme conditions, resulting in high maintenance and labour costs.
Following consultations with solids pumping specialists P+M Pumps, the UK distributor for Vaughan Pumps, Anglian Water purchased three Vaughan PE8N10 Chopper Pumps.

Black and Veatch-designed Butler WRF opens
Black and Veatch has celebrated the opening of the Butler Water Reclamation Facility (WRF) in Peoria, Arizona.
These were supplied with 45kw electric motors for transferring sewage from the Hartford Road pumping station to their Huntingdon Sewage Treatment Works at a rate of 155 L/sec.
Since installation the pumps have not failed, despite ragging and other flotsam material still being present in the sewage streams: also, no mechanical failures have been reported due to abrasive wear.
The Hartford Road pumping station has been operating for 2 years without the need for any unscheduled visits due to pump failures.
In addition the hydraulic performance of the Vaughan pumps exactly meets the target flows set by Anglian Water, with no drop in performance.
Commenting on the pump performance, Mick Tomblin, Site Engineer at Hartford Road said, "We have overcome all of the operational problems we were experiencing, all the pump failures due to ragging have been eliminated - we appreciate the ability of the pump to handle rag matter easily and efficiently.
P+M Pumps offered a guarantee from the outset that these pumps would not block and they have indeed proven reliable, within a very difficult application".
Through their experiences at this Anglian Water site and other installations, P+M Pumps have been able to demonstrate that their products and expertise can bring significant cost-savings.
In most cases, retrofitting Vaughan Chopper Pumps in the correct areas to deal effectively with the process, can be self-financing, with payback periods of less than one year, thereafter minimising the effect to the budget holders.
