Abstract: A rotor assembly for a rotary fluid device that includes a first body at least partially exposed to a process fluid, a second body at least partially exposed to the process fluid, a connecting apparatus that includes at least one connector and at least one seal that connects the first body to the second body and seals the at least one connector from exposure to the process fluid.

Abstract: The disclosure provides a gear pump rotor assembly that includes a rotor body, a rotor head having a plurality of gear teeth and being connected to the rotor body, at least one connector extending between the rotor body and the rotor head, at least one radial deformation control member that extends into at least one gear tooth of the rotor head and reduces the radial deformation of the rotor head relative to the rotor body when a change in temperature causes radial deformation of the rotor body and rotor head.

Abstract: A reciprocating pump and transmission assembly having a one-way clutch is disclosed. The transmission includes an input shaft with an eccentric element, a drive link rotatably connected at one end to the eccentric element and at the other to a driven arm. The driven arm is connected to a driven shaft via a one-way clutch. The oscillating motion of the eccentric drives the drive link and driven arm and the one-way clutch translates that motion into incremental motion of the driven shaft. By changing the stroke length of the drive link various gear ratios between the drive shaft and driven shaft are achieved. The driven shaft then uses a mechanism such as a Scotch Yoke to create reciprocating motion to drive one or more pumping elements.

Abstract: The present disclosure provides a multi-piece containment canister assembly for use in magnetically coupled fluid handling devices such as rotary pumps, mixers, flowmeters or valves. The canister assembly includes a generally tubular single-piece body and an end cap that are sealingly fastened together to form a generally cup-shaped canister. The canister body may be made of strong, non-conductive or low conductive materials, such that it greatly reduces eddy currents. The generally tubular shape of the canister body is easier, and therefore less costly to manufacture than typical cup-shaped canisters.

Abstract: A magnetically coupled fan assembly in combination with an electric rotary motor is provided. The electric rotary motor includes a housing, an inner chamber and a shaft with the shaft having a primary driving end and a secondary end. The fan assembly includes a drive hub assembly, a driven hub assembly and a canister. The drive hub assembly includes a plurality of magnets and is connected to the secondary end of the shaft. The driven hub assembly includes a plurality of magnets and a plurality of fan blades. The canister is sealingly connected to the motor housing and has a portion positioned in a gap between the magnets of the drive hub assembly and the magnets of the driven hub assembly. The canister separates the drive hub assembly and the motor inner chamber from the fan blades, and rotation of the shaft causes rotation of the fan blades.

Abstract: A reciprocating pump having a combination check valve and relief valve is disclosed. The pump includes a pump body having an inlet, an outlet and a pumping chamber. A biasing element provides a force that biases a movable seat toward sealing engagement between a first region of the movable seat and a fixed seat at the inlet. A movable checking element is movable away from a second region of the movable seat when fluid flows in one direction through a passageway in the movable seat. The movable seat also acts as a relief valve wherein the first region of the movable seat disengages the fixed seat if the movable checking element is being forced into engagement with the second region of the movable seat by a force that exceeds the force of the biasing element against a third region of the movable seat.
