John Crane’s Smartflow IG can save up to 180 litres of freshwater per hour on each pump
UPM Nordland Papier is expanding the use of John Crane’s water-saving technology across its paper mill in Dörpen, Germany, after initial installations reduced seal water consumption to almost zero while maintaining reliable pump operation.
The rollout comes as water efficiency moves higher up Europe’s industrial agenda. Around 30% of EU land experiences seasonal water scarcity each year, with pressure typically intensifying between April and September as dry weather, reduced river flows and increased demand affect water availability.
For industries such as paper manufacturing, reducing water used by supporting equipment can create significant cumulative savings without affecting production or asset reliability. The project at UPM Nordland Papier addresses one frequently overlooked source of consumption: the freshwater used as barrier water for double mechanical seals.
UPM Nordland Papier manufactures fine and graphic papers and already operates at approximately four cubic metres of freshwater per tonne of paper, a strong level compared with industry benchmarks.
Improving water efficiency
As part of its continuing efforts to improve water efficiency, the company reviewed barrier water consumption across the numerous pumps fitted with double mechanical seals at its Dörpen mill.
John Crane recommended its Smartflow IG system, which regulates the supply of freshwater so that it is used only when a mechanical seal requires cooling. Depending on the application, the technology can save up to 180 litres of freshwater per hour on each pump.
“With water scarcity affecting a significant proportion of Europe each year, industrial water efficiency is becoming an increasingly important operational and environmental priority. This project shows how addressing a routinely overlooked source of consumption can deliver a meaningful benefit,” stated Christian Naldini from John Crane.
