XFP pump with Contrablock hydraulics limits clogging

XFP pump convinces wastewater treatment plant operator

The Pernes Les Fontaines wastewater treatment plant in France, part of the Rhône-Ventoux mixed water union, treats a daily pollution of 12’000 population equivalents.

Rags in wastewater

The challenge

The operator of Suez Eau France, approached Sulzer – a supplier to the Suez Group – raising the problem of clogging pumps. Jérémie Elluecque, who is in charge of choosing the local equipment, was experiencing recurring problems with the clogging of pumps at the entrance to the station. The sewage lifting station is small and no longer contains a screening basket to protect the pumps from rags or any other waste among the wastewater. Wipes are the main reason for the clogging, and the operator must clean the pumps regularly. This maintenance, more frequent in recent years due to the nature of the wastewater, led to significant expenses for the sanitation service.

The solution

To stop the disturbing clogging, Sulzer proposed the submersible sewage pump type ABS XFP 100E CB 1.3 PE 60/4 E50, equipped with a Contrablock impeller specially designed to treat wastewater containing fibrous and solid materials.

Sulzer offered technical advice and a test period that convinced the operator, who bought the pump in September 2017.

“In addition to optimal operational safety and sustained performance over time, Sulzer’s XFP pump offers reduced energy consumption and low maintenance,” says Mr Elluecque. After two months of use, Suez no longer encountered failures related to clogging. In November 2017, they ordered two additional XFP pumps. “Thanks to this reactivity, Sulzer strengthens our will to continue our partnership”, concludes Mr Elluecque.

Choosing the XFP pump is a guarantee of reduced clogging, lower energy consumption, and lower maintenance costs. Mr Jérémie Elluecque, Treatment Plant Manager, Rhône sector, Suez Eau France
