About CleanStream®


CleanStream® is the Water treatment division of Marshall Pump Systems Ltd, a development of the engineering company George Sumner Ltd.

George Sumner is still trading today, supplying sub-contract engineering services. After the First World War and the decline in the local textile industry, George Sumner Ltd diversified into the wider industrial market and this eventually led to an involvement with pumps. They still manufacture and supply the Sumner rotary gear pump worldwide today.

The continued growth in this market, led to the formation in 1965 of Marshall Pump Systems Ltd who continue to specialise in the pump market today.

Our engineering background means we tend to approach problems differently from most water treatment and pump distribution companies in that we look to supply the best product from an engineering point of view..

We specify, design, manufacture, assemble, install & maintain packages to meet our client’s requirements and are fully accredited to ISO 9001:2008 ensuring that you, our valued client, get quality products and a high quality service every time.
