Mono® NOV, Europe’s leading designer and manufacturer of progressing cavity pumps, parts, grinders, screens and packaged systems, has proved to Carillion, a service partner to a leading UK Water plc, that the Chroma pump is a cost effective solution to reducing maintenance costs at Waste Water Treatment Works.

Chris Holden, Maintenance Manager for Carillion, was faced with increased maintenance costs to a number of sewage sludge pumps at one of the waste water treatment works that he maintains. A decision was required to either repair or replace the seepex pumps, but both options were expensive. Alternative technology was also considered to transfer the sludge, but again this attracted high installation costs.

The Mono Chroma option, which has been designed to be directly interchangeable with the seepex® BN series, was the solution to all his needs. For less than the cost of the internal pump parts from seepex, and substantially less than purchasing a replacement seepex pump or other pumping technology, the Chroma pump was supplied.

Complete with motor gearbox, all mounted on a baseplate that matched the previous seepex pump exactly, it was simply a case of dropping the Chroma pump into position, reconnecting the pipework and electrics and the pump was up and running, all with no additional installation costs.

Since the installation in May 2008, the pump has performed trouble free and is backed up by a standard 5 year warranty.

With no pipework or electrical modifications required, and full size access ports as standard to enable easy de-ragging of the pump, without having to remove from the pipework, the Chroma is designed to meet all Water Plc and WIMES industry standards, offering peace of mind to the end user.
