NOV® MONO® MAKES THINGS ‘EZ’ FOR THAMES WATER

Thames Water has installed a revolutionary EZstrip maintain-in-place pump to improve efficiency and reduce downtime at its sewage treatment works in Dorking.

The site’s previous equipment, which transferred sludge from the primary settlement tank into a picket fence thickener, was failing and causing significant down time for the plant. Mono’s EZstrip sewage pump, which can be fully stripped down and maintained in just 30 minutes, provided the answer they were looking for.

Gavin Parker, sewage works operator at Thames Water, commented: “It would normally take a full day just to disassemble our previous equipment, so after de-ragging the pump and putting it back together we had lost around two and a half days in total, which as you can imagine is a major setback.

“We specified the Mono EZstrip sewage pump because we were keen to try out the company’s latest innovation for ourselves, and I have to say, it has definitely delivered – maintenance and downtime at the works has been significantly reduced.

“Also, because the pump requires no dismantling space, it was easily installed into the same space as the existing pump with room to spare. We are very happy with the pump’s performance, everything is working perfectly.”

Mono’s EZstrip progressing cavity pump is the biggest leap forward in progressing cavity (PC) pump design for 30 years and is an extension of Mono’s popular Compact C Range. The EZstrip has been specifically designed to provide a quick and easy way to disassemble, de-rag and maintain a PC pump in-situ, eliminating the costly maintenance and down time that servicing can often cause.
