Seepex pumps are forming part of Insource Energy’s new anaerobic digestion plant in Wales, which converts food waste from the Premier Foods RF Brookes ready-meal facility at Rogerstone into energy to power the factory.

Progressive cavity pumps from Seepex are being used to perform the majority of pumping duties to and within the plant, transferring a range of products at variable flow rates. 

A Seepex macerating pump from the BTM range with integral knives has recently been fitted to handle food waste delivered to the AD intake in tote bins. 

Seepex macerators have also been installed to ensure that the correct particle size is achieved to comply with ABP regulations for mixed food waste.

Within the plant there are a further 12 Seepex pumps on transfer duties, feeding the pasteuriser, pumping from the pasteuriser at temperatures up to 70°C and transferring material between tanks. 

Key benefits of product application
