Church End Brewery produces a wide range of over 40 distinct products, including fruit, herb and chocolate malt beers. Before the Mono progressing cavity pump was installed, the brewery had to manually empty waste from its equipment, a very time and labour intensive process.

To provide a solution, the brewery specified Mono’s Compact C Range pump, which has been installed to mix water and crushed barley (the setting of the mash) and then transfer the resultant spent grains at 50 l/min to a storage tank prior to disposal.  As the mash is a highly viscous product, the pump was designed with a square inlet to assist the product into the pumping element.

Stewart Elliot, Managing Director at Church End Brewery, commented: “We had a number of companies quote for the job, but right form the outset Mono stood out from the crowd. They sent someone out to us straight away to analyse the situation and then quickly came back with a very competitive quote.

“Also, Mono’s specification was spot on – other competitors came back with over specified quotes, which were not what we asked for. We are very happy with our Mono pump, not only has it performed extremely well, it is saving us a lot of time and sweat from manually emptying the mash!”

The Compact C Range of progressing cavity pumps 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 up to eight meters. 

A progressing cavity pump consists of a single helix rotor, which revolves within the double helix stator.  This action creates a continuous cavity that carries the pumped product intact through the pump as the rotor rotates. The unique design is highly efficient at handling difficult to transfer viscous products and ingredients, such as sugar syrups, sauces, soups and gravies, meat slurries and pastes, with or without solid inclusions and liquids containing entrained gases.
