Maintenance is a piece of cake with new pump

As part of a drive to reduce maintenance downtime, 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% sludge cake from the site's centrifuge dewatering process to a storage skip for later removal from site.

Specifically designed to minimise the time and cost involved in maintaining a progressing cavity pump, the new EZstrip cake pump can be completely stripped down and rebuilt in just 15 minutes, without the need to disconnect or remove any pipe work.

The pump features a highpurpose- designed feed chamber that is disconnected by removing only a few screws and allows access to the pin joint area for removal of any blockages or compressed cake. Once the rotor assembly is disconnected from the screw conveyor, the rotor and stator can be removed.
