Munch pups improve efficiency at Caldbeck water treatment plant 08 July 2011

Two high-performance Munchpump packaged pumping systems, from Nov Mono, have been specified by United Utilities for its wastewater treatment works in Caldbeck.

Chris Cooke, area maintenance engineer at Calbeck WwTW, says that the new Munchpumps are already improving efficiency by preventing pump blockages and minimising downtime.

He explains that the pumps, which each consist of a Compact 'C' progressing cavity pump and CB201 muncher, were installed to replace the plant's existing centrifugal pumps that were, over time, causing reductions in flow or blocking completely.

"We knew Nov Mono to be an extremely reputable brand, particularly in raw sewage applications, and were keen to try out the company's product offering for ourselves. Since the installation, maintenance and downtime at the site have been significantly reduced," states Cooke.

Nov Mono's Compact C progressing cavity pump range has been designed to fit into compact spaces, while reliably performing to the maximum duty requirement of the application. The pump uses positive displacement for process control, variable speed for accurate dosing and features a suction lift capability of over eight meters.

The CB201 Muncher is designed to meet above-ground pump station requirements for delivering a conditioned wastewater through small bore pipework into a receiving wastewater treatment package.
