The benefits of NOV® Mono®’s EZstripTM technology were highlighted by a new order from a Danish wastewater treatment plant. When sourcing pumps for a new sludge dewatering process, the Odense WWTP chose 8 Mono EZstripTM cake pumps and 16 Compact C Range progressing cavity pumps.
The decision was based on the reduced maintenance time the pumps offer, together with speed of delivery from Mono. The same advantages also led the plant’s engineers to specify Mono’s EZstripTM and Compact C Range pumps for use on new polymer dosing equipment that was being ordered, rather than the competitor pumps which were offered as standard.
“When we were invited to tender for the sludge dewatering process, we took an EZstripTM demonstration pump to the plant,” explains Product Manager Michael Roug, from AxFlow A/S, Mono’s Danish distributor who supplied the pumps. “We explained how it could be disassembled, de-ragged and maintained in-situ, all in a fraction of the time that process normally takes. Coupled with the fact that Mono was also very competitive in terms of cost and speed of delivery, this made it an easy decision.”
Mono’s EZstripTM pumps incorporate the best aspects of Mono’s thoroughly proven Compact C Range pumps, and can 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 to just 30 minutes.
