Publication number: 20230375087Abstract: An improved bearing or bushing body extraction from a stuffing box using jack screws is provided. The bearing or bushing seal body includes at least one jack screw on each half of a split body. The jack screw passes axially through the sidewall of the body to the inner flange of the stuffing box and turning the jack screw against the inner flange to lift the body from the stuffing box. A single inner threaded or double threaded insert with a reverse outer thread and standard inner thread is inserted into the bottom wall of the body so that the body may be installed flush against the inner flange. By turning the jack screw through the insert and against the flange, the seal body is pushed out rather than pulled.Type: ApplicationFiled: August 7, 2023Publication date: November 23, 2023Applicant: SEAL-RYT CORP.Inventors: Thomas B. Monahan, Michael F. Huard

Publication number: 20230243427Abstract: A fluid sealing system for a rotary mechanical device including a pillar lantern ring having a bottom and a top end cap with pillars or columns connecting the end caps is formed by additive manufacturing. The bottom annular end cap has an outside face and an opposed inside face defining a height therebetween and the upper annular end cap has an inside face and an opposed outside face defining a height therebetween with a plurality of integrally formed substantially cylindrical axial columns connecting the two opposed inside faces of the two end caps.Type: ApplicationFiled: January 29, 2023Publication date: August 3, 2023Applicant: SEAL-RYT CORP.Inventors: MARK R. WILKINSON, THOMAS B. MONAHAN

Patent number: 11674597Abstract: An improved remotely adjustable gland follower for a stuffing box of a rotary or reciprocal mechanical device is provided. In one embodiment of the invention, the gland follower includes a body portion with at least one cylinder having a fluid inlet at the power end and a piston. The piston has a hydraulic end positioned within the cylinder and an opposed packing face surrounding the shaft and configured to extend into the seal cavity. The piston engages and compresses the packing in the seal cavity when pressurized by fluid introduced into the fluid inlet at the power end of the cylinder. At least one o-ring groove may be formed in the hydraulic end of the piston to receive at least one o-ring for improving the hydraulic seal in the cylinder.Type: GrantFiled: September 5, 2021Date of Patent: June 13, 2023Assignee: SEAL-RYT CORP.Inventor: Thomas B. Monahan

Patent number: 11054036Abstract: A fluid sealing system for a rotary mechanical device includes a pillar lantern ring having two end caps with pillars or columns connecting the end caps. A bushing or bearing seal element is positioned at the bottom of the seal cavity and the pillar lantern ring is positioned adjacent the element at the flush port with compressible packing rings between the lantern ring and the gland follower. The pillars or columns are axial supports to prevent the ring from being crushed when the gland follower is tightened down. The pillars allow for a larger reservoir volume of flush in case of temporary flush loss compared to a conventional lantern ring with holes between the outer and inner groove surfaces of the lantern ring. The outer surface of the lantern ring is closely dimensioned to the inner bore of the stuffing box. In one embodiment the lantern ring is a suspended lantern ring with an inner diameter greater than the shaft to avoid any and all contact with the shaft in order to extend its working life.Type: GrantFiled: September 27, 2018Date of Patent: July 6, 2021Assignee: SEAL-RYT CORP.Inventors: Mark R. Wilkinson, Thomas B. Monahan
