在湿井24 / 7固体的有效和可靠的抽，即使当重型潜水泵'流氓'项目存在特殊的挑战，通常是理所当然的，网站或任何情况。 根据亨廷顿固体泵送和混合专家P＆M泵高兴地提供了一个有效的解决方案，从而有助于在彼得伯勒监狱工程师，以消除堵塞泵所产生的问题。
Opened in 2005, HMP in Peterborough has the distinction of being the first mixed prison in the UK with both male and female wings. P&M‘s Vaughan Chopper pumps were considered for the initial procurement specification during 2004, however the decision was taken (essentially on price) to install another type of submersible pump.
The prison population at Peterborough has increased steadily over several years to around 900+ ‘customers’ and in December in 2011 P&M Pumps were contacted by the engineering services company contracted to maintain pumps, sewers and pipe work systems on the site as frequent problems were occurring as a result of blockages. In fact, the existing pumps were being lifted every week for cleaning and maintenance, where on some occasions suction tankers were called in to maintain the removal of effluent. This of course amounted to significant extra cost and disruption as the pumps could be out-of-action for several days at a time.
P&M Pumps were invited to demonstrate the effectiveness of their Vaughan Chopper pump by bringing their trailer mounted pump set on to site. During the trial, engineers brought items that were regularly causing the existing pumps to block, including gloves, towels and even fleece jackets. The demonstration was a success as the offending items were handled by the chopper pump with impunity.

Within these numerous UK prison sites P&M Pumps have demonstrated the Vaughan Chopper Pump to be an effective and reliable pumping option for the most challenging solids handling applications requiring vital 24/7 operation.
