As part of a drive to reduce maintenance downtime across the board, Welsh Water has installed an innovative EZstrip Cake Pump from framework supplier NOV Mono at its sewage treatment works in Cardigan, West Wales. The Mono progressing cavity (PC) Cake Pump has been installed to transfer 22 – 28 per cent sludge cake from the site’s centrifuge dewatering process to a storage skip for later removal.

The EZ strip cake pump will ensure the continuous reliability of the sludge treatment plant on site and reduce potential plant downtime allowing sludge to be processed with a reduced risk to the wastewater compliance on site. Designed to minimise the time and cost involved in maintaining a progressing cavity pump, the EZstrip cake pump can be completely stripped down and rebuilt in just 15 minutes, without the need to disconnect or remove any pipe work.
