Patent number: 11655897Abstract: A multi-layered lip seal comprising a dynamic layer optionally having a filler incorporated therein and a static layer optionally having a filler incorporated therein is described. The lip seal has an annular ring shape, wherein an inner diameter of the ring shape is curved in an axial direction so as to give the lip seal a J-shape when viewed from a cross-sectional perspective. Fillers that can be included in static layer include stiffening filler, reinforcement fillers, conductive fillers and/or abrasion resistance fillers. Fillers that can be included in the dynamic layer include wear resistance fillers. The use of specific fillers in specific layers of the multi-layered lip seal allows for certain segments of the lip seal to be imparted with the benefits of the filler without negatively impacting other segments of the lip seal.Type: GrantFiled: September 9, 2021Date of Patent: May 23, 2023Assignee: Garlock Sealing Technologies, LLCInventors: T.

Patent number: 11073211Abstract: A diaphragm seal with a unique profile at its outer diameter and a high-pressure seal used to at least partially envelope the outer diameter of the diaphragm seal is described. The high-pressure seal may envelope an outer diameter side of the diaphragm seal such that the high-pressure seal creates a barrier between the diaphragm seal and the interface between an upper pump housing portion and a lower pump housing portion in which the diaphragm seal can be installed. The high-pressure seal may provide a “gripping” force on the diaphragm seal so as to inhibit or prevent extrusion of the diaphragm seal in either a radially inner or radially outer direction when installed in a pump housing.Type: GrantFiled: February 12, 2019Date of Patent: July 27, 2021Assignee: Garlock Sealing Technologies, LLCInventors: Matt Krempa, Dan Naugle

Patent number: 10753478Abstract: A bearing isolator having a simple design and made from low-cost materials but which performs comparably to other higher-cost bearing isolators is described. The bearing isolator generally includes a rotor having a snap fit feature protruding from a radially-oriented flange and a stator having a snap fit feature recess for receiving the snap fit feature to thereby join together the stator and rotor without need for, e.g., a separate unitizing element. Furthermore, the rotor and/or stator can be made from lost cost material, such as a nylon/moly material. In some embodiments, the stator further includes a lip seal biased against the radially-oriented flange of the rotor, which, when combined with the labyrinth passage formed at least in part by the snap fit feature and snap fit feature recess, helps to prevent egress and ingress of lubricant and/or contaminates.Type: GrantFiled: November 7, 2017Date of Patent: August 25, 2020Assignee: Garlock Sealing Technologies, LLCInventors: Christopher Tones, Christopher Fink

Patent number: 9987577Abstract: A kammprofile gasket is provided. The kammprofile gasket forms a flow aperture into which an object, such as a strainer or orifice plate, may be machined into the gasket to provide additional functionality. The gasket has a core material with a sealing material overlaying a portion of the core material such that a seal is formed between opposing flanged surfaces. The core material may be machined such that a base plate for an orifice or a plurality of support beams extend into the flow aperture. The plurality of support beams may provide support for a filter or strainer coupled upstream to the core material. The base plate may provide an inclined surface, such as a cone, to an orifice where the cone functions to direct excess flow away from the orifice to self flush.Type: GrantFiled: September 4, 2013Date of Patent: June 5, 2018Assignee: Garlock Sealing Technologies, LLCInventors: Chad Yoder, Matthew Tones, Christopher Tones
