South West Water approves Nov Mono pump innovation 15 June 2010

South West Water has approved the EZstrip 'maintain in place' progressing cavity pump from NOV Mono for use at all its waste water treatment plants.

According to the South West Water approval team, it's all about improving efficiency and reducing downtime.

"Due to its simple construction and innovative PC pump design, we expect to see a significant reduction in downtime for rotor/stator replacement, which, in turn, will save on both process time and labour costs," South West Water's approval team leader.

"As well as dramatically reducing asset downtime and maintenance costs, the EZstrip pump will eliminate the difficulty, time and cost involved to de-rag a pump. Mono has demonstrated an innovative solution backed by the Mono brand," he adds.

EZstrip was designed to provide a quick and easy way to disassemble, de-rag and maintain a progressing cavity pump in-situ. Its suction chamber has a two-piece design that can be dismantled and rebuilt with just a spanner and an Allen key.

NOV Mono claims that, on average, the pump can reduce the maintenance time needed to replace a rotor, stator, coupling rod and drive train by up to 95%. Also, the average time to completely strip down a pump and replace the drive train elements can be one full day – whereas for EZstrip it is just a 30 minute job.
