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 unique and 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 biggest 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 180m. The MCE pump is designed for the common consistency range of 10-12% and a pressure rating of 25bar.
Sulzer’s 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.
The MCE93-400 pumps are manufactured at Sulzer’s factory in Kotka, Finland. The first big MCE pumps have been dispatched to a major pulp manufacturer in South America.
