Abstract: Filtration apparatuses and screen changer devices for filtering polymeric material as well as spacer plates, and face plates for the screen changer devices and related methods are shown and described herein.

Abstract: Modular fluid processing apparatuses, modular components and related methods are provided. A fluid processing apparatus for use in fluid processing systems can include a housing comprising first body half and a second body halves that are secured together. The first body half has one or more half bores that extend along a length of the first body half and the second body half has one or more half bores that extend along a length of the second body half with the one or more half bores in the first body half aligning with the one or more half bores in the second body half forming one or more full sleeve-receiving bores. The fluid processing apparatus can include one or more sleeves that are securable between the first and second body halves within the one or more sleeve-receiving bores to form piston pathways within the housing for receiving pistons.

Abstract: Seal systems are provided that use a variety of seals to seal fluid processing apparatuses, such as gear pumps, to facilitate the prevention of a leakage of fluids from the respective fluid processing apparatuses. Fluid apparatuses that use such seal systems are also provided. Methods of uses, making, and assembly of seal systems are further described herein.

Abstract: Extrusion die systems, die changers and related methods are provided herein. The die changer for changing of dies in and out of an extrusion line can include a housing having a main supply feed bore therethrough for directing a flowable material and a channel oriented transversely to the main supply feed bore. The die changer can include a slide plate movable through the channel and transverse to a direction of flow through the bore. The slide plate can include an elongate body having a first section and a second section. A first bore can extend through the first section of the elongate body of the slide plate and a second bore can extend through the second section of the elongate body of the slide plate.

Abstract: A filtration apparatus for use in polymer processing includes a housing having an internal bore for directing polymer flow and a channel oriented transversely to the bore. A slide plate for supporting filters is movable through the channel and across the bore. An annular upstream seal ring sealably contacts the slide plate. A surface of the upstream seal ring facing the upstream direction is angled with respect to the bore. A plurality of ring segments are arranged to form an annular segmented ring. The segmented ring presents a tapered ring surface that is generally complimentarily angled relative to the angled surface of the upstream seal ring. Pressurized polymer flowing through the bore imparts radially forces on the ring segments, causing the ring segments to impart axial forces on the upstream seal ring to enhance the seal interface between the upstream seal ring and the slide plate.
