Abstract: One or more techniques and/or systems are disclosed for an improved barrier seal for use on a rotating shaft of a pump to mitigate leakage of fluids along the shaft. The body of the barrier seal may comprise a one-piece combined bushing and seal that can be selectably fastened to the pump bracket. Internal and external channels in the body can operably hold gaskets, internally dynamic seals, and externally static seals, inside the stuffing box of the pump bracket. A lubricant port can be disposed on a flange of the seal portion to provide lubricant to the interior of the barrier seal, which can also be fluidly coupled with the outside of the seal. A pressurized lubricating fluid can also help mitigate leakage of pumped fluid by pressurizing between static gaskets on the outside, and provide lubrication for the rotating shaft on the inside of the seal.

Abstract: One or more techniques and/or systems are disclosed for a universal-type bracket that incorporates a substantially uniform diameter through-bore. This allows the bracket to accept current sealing arrangements used in these types of pumps, while providing the same or better sealing options as current individual designs. The single through-bore can have multiple undercut features for holding a pump shaft bushing, with an increased wall thickness to allow for an appropriate interference fit with the walls of the through-bore, for example, similar to previous designs. Retaining ring grooves can be added to the through-bore, and retaining rings may be used to provide a positive shoulder for the seal or packing rings to seat against inside the bore. This may allow for various sealing options, such as stuffing seals, one-piece barrier seals, cartridge seals, BTR seals, component seals, and more.

Abstract: One or more techniques and/or systems are disclosed for a universal-type pump casing that allows for coupling to various piping couplers, for various sizes of fluid lines. This can allow the pump casing to accept the majority of current fluid line coupling, for various fluid line sizes used with these types of pumps, thereby eliminating the need to have a different casing for each different sized fluid line. A universal-type pump casing with a proximal end engaged with a pump bracket, and a distal end affixed to an end plate to define the pumping chamber. A first and second port can have an opening of a predetermined diameter, with a port face that can couple with various modular port flanges, to provide different port flange configurations.
