NOV Mono Installs EZstrip PC Pump at Welsh Wastewater Treatment Plant

Contributed by: PumpScout Staff

NOV Mono is a global manufacturer of progressive cavity pumps and related equipment. The company recently completed a project at Dwr Cymru’s Crymych treatment plant in Pembrokeshire, Wales that will provide an extra layer of protection and guaranteed quality of the treated sewage under any flow conditions.

To achieve this, Mono installed its innovative EZstrip progressive cavity for sewage transfer duties at the plant. The pump draws sewage from the center of the final settlement tank, pumps the sewage back up to the head of the treatment system and returns it back through the filter bed to the final tank. This ensures that the plant’s biological filters do not dry out and remain effective, even in very low flow conditions. Consequently, the quality of the final sewage is maintained within required boundaries at all times.

EZstrip design allows the pump to be maintained in-place, providing a quick and easy way to disassemble, de-rag and maintain the pump without the need to disconnect suction and discharge pipework. This feature reduces a typical 8 hour maintenance project to just 30 minutes. Available in cast iron or stainless steel, and with a choice of rotor and stator materials, the pump requires only basic tools to maintain, and can be retrofitted into existing installations where a Mono Compact C pump has been used previously.

Mono offered the treatment plant a full turnkey package which covered all stages of the project, from initial site survey, design and manufacture, through to full mechanical and electrical installation. Working closely with the project’s civil contractor, Mono installed the pump, suction pipe, rising main, control panel, overpressure and high temperature devices and completed the final testing and commissioning. Both the electrical and mechanical work were also handled by Mono.

Since the completion of this project, Mono has also completed a very similar project at Dwr Cymru’s Lamphey treatment plant.
