  • Sulzer to supply pumps and mixers to the new bioproduct mill in Kemi, Finland
    March 24, 2021
    Metsä Fibre, part of the Finnish forest industry company Metsä Group, and Sulzer Pumps Finland have signed an agreement for the supply of process pumps, medium-consistency pumps and mixers for the main processes of the bioproduct mill that will be built in Kemi. The delivery will include several hundred devices.

  • AHLSTAR and SNS pumps throughout corn ethanol process
    FS Bioenergia, located near Lucas do Rio Verde, Mato Grosso, is the first corn-only ethanol plant in Brazil. The production started in 2017 and the annual capacity is 250 million liters today. The facility utilizes the latest process technologies from ICM, an innovative company headquartered in Colwich, KS, USA that has become a world leader in biorefining technologies and processes. In addition to bioethanol, some high-value coproducts such as corn oil as well as high-protein and high-fiber dried distiller’s grains are produced. The plant also generates electricity from the biomass, partly for internal use and the surplus for sale.

  • AHLSTAR pumps with maintenance-free dynamic seals
    The paper mill includes a conventional wastewater treatment plant which treats about 20'000 m³ per day of process effluents. At the output of the plant, about 30% of the discharge water is reintroduced into the mill circuit and the remaining 70% is returned to the Moselle river. Despite the increasing stringency on the quality of the discharge water, no environmental incident has occurred since the start-up of the plant.

  • Wear resistant process pump for metals and fertilizers applications
    In the minerals and metals processing industry or in fertilizers production, ideal application conditions where a pump is operating at its best efficiency point (BEP) and the system is stable very seldom occur. Wear and corrosion are bound to a shortened lifetime of the pump in demanding applications. Read the whole article.

  • Pump solutions for mine water management
    Mines require water. At the same time, because many mine working areas are below the water table, the removal of water is a major challenge. Water is critical for every mine site – without water the mine could not operate. Pumps are, therefore, one of the most used machines in mines today. In this article we will review the concepts of mine water and mine water management as well as the most common pumping applications. Read the whole article.

  • Expert solutions for mining and quarrying
    The mining, quarrying and construction industries present some of the most challenging applications encountered by pumps. The range of process fluids handled varies quite significantly across these processes, ranging from clear water to heavy slurries and from alkaline, pH neutral to highly corrosive fluids. As well as having to deal with the process requirements, products must also be compliant with the environmental and legislative constraints in play across geographies. Read the whole article.

  • Energy efficiency of pumping systems
    Pumping systems account for more than 20% of the world’s electrical energy demand, and in certain industrial plant operations they can be responsible for between 25% and 90% of the energy usage. Improving the energy efficiency of the pumping system will reduce production costs and support green credentials. Read the whole article.
