Tower Bridge sticks with progressing cavity pumps 25 January 2011

A high performance Compact C range progressing cavity pump, from Nov Mono, has been installed at London's Tower Bridge, to handle rainwater and the ingress of ground water from the River Thames.

Tower Bridge, which uses a progressing cavity pump in each of its bridge legs for dewatering purposes, requested a like-for-like replacement from Mono after the previous Mono PC pump, which had run smoothly for more than 10 years, reached its end of life.

"The Mono pumps transfer ground water to the surface 100 feet above before it is transferred to the main drainage system," explains David Duffy, technical officer at Tower Bridge.

"We specified Mono, because, as well as being the original equipment supplier, we know the Mono brand to be reliable and trust the pump to do the job well. The Mono Compact C is extremely dependable, reducing maintenance and making our process much more efficient, which is extremely important," he adds.
