NOV Mono has expanded its range of maintain-in-place pumps. The largest EZstrip transfer pump now has a 225m3/h capacity, designed for an even wider range of wastewater applications.
The EZstrip transfer pumps were designed to incorporate all the best aspects of NOV Mono's Compact C Range pumps.
According to the company, the EZstrip technology on which they are based provides a quick and easy way to disassemble, de-rag and maintain the pump in-situ, according to the company.
This is designed to 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 EZstrip pumps we listened very carefully as our wastewater 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 EZstrip 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 EZstrip range allows," added Lambert.
The 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.
