Sulzer launches the world’s biggest medium-consistency pump
Sulzer announces the launch of what it claims is the world’s biggest medium-consistency pump, the MCE93-400. The new MCE pump size is Sulzer’s answer to customers’ demand for bigger production rates in pulp mills.
Pumping of liquids with a high dry solids content, referred to as medium consistency (MC), is essential for the processes in the pulp and paper industry. The MCE pumps from Sulzer are said to achieve a reliable performance level when it comes to the capacity range as well as to the temperature and pressure of the pumped medium.
In recent years, the production rates of the industry have increased remarkably. Sulzer developed the MCE pump size for a customer project with record-breaking values. The capacity of the pump reaches up to 10,000 ADMT/d (air dry metric tons per day), the flow up to 940 l/s and the head up to 180 m. The MCE pump is designed for the common consistency range of 10-12% and a pressure rating of 25 bar.
“The new MCE93-400 medium-consistency pump size is an excellent addition to Sulzer’s MC equipment offering,” says Jussi Heinonen, product manager for MC equipment at Sulzer. “It has been designed to operate very efficiently, thus saving energy, water, and chemical costs in the pulp and paper mill processes. The unique and innovative design features of the pump minimize its life cycle costs.”
Sulzer says its MCE centrifugal pumps are suitable for the most demanding process applications to pump medium-consistency fibrous suspensions, slurries with a high dry solid content, and media with a high gas content. They cover all medium-consistency applications for pulp, paper, and board as well as related biomass and biofuel applications.
