With dwindling maintenance budgets and rising levels of difficult to handle sludges and effluents, the Water and Wastewater industry is experiencing some of its most challenging times yet. However, there are new pumping solutions available that can make a real difference.Simon Lambert, Sales & Marketing Director for NOV® Mono®, looks at how its revolutionary EZstripTM Progressing Cavity (PC) pump has been developed to help facilities meet the demands of modern wastewater treatment.
Mono surveyed their customer base in the Wastewater industry to find out what common problems they were facing and found that the overriding response was that ragging has become a serious problem and is increasing in severity to the point where it can cause serious disruptions to the efficiency of the treatment process.
Our solution was the EZstripTM, which has been specifically designed to provide a quick and easy way to disassemble, de-rag and maintain aPC pump in-situ, eliminating the costly maintenance and down time that servicing can often cause.
On average, the EZstripTM can reduce the maintenance time needed to replace a rotor, stator, coupling rod and joint by up to 95%. The average time to completely strip down a pump and replace the drive train elements is usually one full day on typical sludge pumps; the EZstripTM reduces this to just a 30 minute job.
By completely rethinking the design of the suction chamber and drive train element of a PC pump, we have also been able to eliminate the difficulty, time and cost of de-ragging and maintenance.
The chamber of the EZstripTM has a two piece design, which can be dismantled and assembled in place and can be opened up and rebuilt with a spanner and an Allen key in a fraction of the time previously required.
