NOV® Mono®, Europe’s leading designer and manufacturer of progressing cavity pumps, Munchers® and associated equipment, has announced an expansion of its revolutionary range of maintain-in-place pumps. The largest EZstripTM transfer pump now has a 225m3/h capacity, making these pumps ideal for an even wider range of wastewater applications.
Recognised as the biggest leap forward in progressing cavity pump design for 30 years, the EZstrip™ transfer pumps were designed to incorporate all the best aspects of NOV Mono’s popular and thoroughly proven Compact C Range pumps. The EZstripTMtechnology on which they are based provides a quick and easy way to disassemble, de-rag and maintain the pump in-situ. This can dramatically reduce the time needed to replace a rotor, stator, coupling rod and drive train by up to 95%, cutting the typical day-long maintenance operation down to just 30 minutes.
“Before we designed and launched the original EZstripTM pumpswe listened very carefully as our waste water industry customers described the typical problems they faced,” explains NOV Mono’s Group Sales and Marketing Director, Simon Lambert. “They told us that ragging was becoming a serious problem because of an increasing volume of unsuitable items finding their way into the sewers. They wanted a pump that would minimise downtime in a significant way and the new EZstripTM range was our response.
“Those customers then went on to tell us that they needed EZstrip™ pumps with a greater handling capacity, and once again we have responded with a proven and highly effective answer to their requirements.” The three new models added to the EZstripTM range offer handling capacities of 94m3/h, 140m3/h and 225m3/h. (The previous largest capacity pump in the range was able to handle 165m3/h).
“Many of our customers can’t believe that it is possible to de-rag and maintain a pump as quickly as the EZstripTM range allows,” adds Simon. “However if they visit our website (http://www.mono-pumps.com/en-uk/ezstrip) they can view a video which proves that we’ve turned the seemingly impossible into reality.”
The EZstripTM pumps can be installed in new plants or retrofitted into existing Compact C applications. Electrical disconnection is not required, while suction and discharge pipes remain untouched. No special tools or skills are required for normal de-ragging operations.
All pumps provide dry run protection, during which operational parameters remain unaffected. Both cast iron and stainless steel versions are offered, plus an option to incorporate WRAS-compliant elastomers, a pre-assembled drive train and a two-year warranty.
