Metso offers new high performance slurry seal

first_imgMetso is launching a new slurry seal to meet the increased sealing demands from its mining customers. The focus has been “to offer a sealing solution that minimizes dilution of sealing water into product, eliminates leakage to atmosphere, increases life time of the seal by preventing slurry from entering the seal chamber and allows easy conversion from box packing solutions to mechanical seal solutions.”Metso’s says the new ESF design seals “satisfy the demand for advanced and reliable sealing solutions on even the heaviest of slurry applications typically found in mining applications.” Customers have requested mechanical seals for tougher and tougher applications due to environmental reasons; while satisfying the goal of reducing water consumption. Metsop states that to satisfy these requirements it was necessary to develop new seals. Metso’s says its slurry pump ranges are known for their long life, high operational performance with minimum power consumption and total ease of service.The main features and benefits of the mechanical slurry seal ESF are as follows:·      The ESF seal is designed to fit into the standard Orion Series pump flushed gland housing. For the VASA HD a convenient seal adaptor is useCartridge design makes it easy to install·      Retrofit installations are quick and easy when converting a packed seal pump. “Plug-and-play”·      Tungsten Carbide seal faces are standard and provides longer life for the tougher applications·      Flushed gland port along with the internal chamber creates a barrier of clean continuously replenished fluid to prevent incursion of slurry material to the seal faces which increases service life of the seal·      Centering clips are self storing and are used to keep the seal faces in position when impeller to casing clearance is adjusted·      Radial lip seal to ensure that the seal runs in a clean water environment·      O-ring mounted seal faces that can be replaced in the field without special tools reduces repair costlast_img read more
