Catalog excerpts

Instream – Close Coupled Pumps The Instream is designed to provide a high level of component interchangeability with the Unistream and Eurostream ranges; providing extra benefits including simplification of design, savings in time and cost to standardisation of pipework layout, and a reduction in spares requirements. Other mainline features include impellers cut to duty thus saving energy consumption without extending the standard delivery. Instream hydraulic components are interchangeable with the close coupled Eurostream and Unistream range, therefore, saving stock holding of spare parts within factories or buildings. Typical Applications: • Circulating duties • Water boosting • Greenhouse irrigation • Heating and air conditioning • Fuel transfer • Process cooling
