design of the mechanical seal itself. The sealing function of the vessel can only be guaranteed and maintained if the complete system is correctly selected, installed and maintained. when a mixing system is being commissioned, support and training for the equipment operators are very important to allow work to proceed rapidly and without problems. Once the plant is up and running, training and support are often the cornerstones needed to ensure high availability of the complete mixing system. n Edited by Charles Butcher References EKATO the Book (2012): Handbook of Mixing Technology, 3rd edition, EKATO GmbH, ISBN 978-3-00-038660-2.
