  • Patent number: 11448224
    Abstract: A pump is provided for immersion in a fluid reservoir, such as a pit or lagoon containing liquid manure, from a position at an edge of the reservoir. The pump may be adapted for connection to a farm vehicle, such as a tractor, positioned at the edge of the reservoir. The pump comprises an extensible body, fluid conduit and drive means in order that a length of the pump may be varied in order to accommodate a variety of reservoir fluid heights. In addition, the pump may be pivotable relative to at least a portion of a frame in order that the entrance angle may be adjusted. The pump may comprise a housing with an inlet and an outlet, the outlet in fluid communication with the fluid conduit. An impeller within the housing may direct fluid from the inlet to the outlet in the housing.

The multi wiper member circular support carries from about five to nine wiper members each mounted within a slot extending substantially the length of the support, with each wiper member being centrifically urged outwardly to wipingly engage an inner surface of a round or elliptical walled pump housing. Eccentric action enables the wiper members to be extended to create a large space between adjacent wiper members as an inlet is passed. As the wiper members pass by the inlet, the acentric cylindrical wall of the pump housing begins to compress the wiper members into the support, thereby reducing the space between adjacent wiper members in a compressive manner.

  • Patent number: 5507628
    Abstract: A lift out coupling for a submersible pump has a close quarter elbow that connects to an upward facing threaded discharge of standard submersible pumps, and can be rotated in the outlet without interfering with the pump body. In the past, it has been necessary to have an extension pipe that extends down to connect to a threaded outlet with the elbow portion above the pump itself. The coupling has a lift out portion with a close quarter elbow for connection to the threaded discharge and rotatable without interfering with the submersible pump, the elbow has a first sealing flange connected thereto with a lift hook for raising the pump and the lift out portion on guide rails. A fixed portion has a second sealing flange for mating with the first sealing flange, the second sealing flange connected to a discharge elbow forming part of a base support frame for installation in a sump, the frame having guide rails extending upward therefrom in the sump.

  • Patent number: 5344291
    Abstract: A combination frame arranged between a centrifugal pump and a driver, such as a motor, the combination frame having in a central region thereof a compartment for holding shaft bearings and a quantity of oil, and a pump adapter frame arranged between said compartment and said pump, and a driver adapter frame arranged between said compartment and said driver, the pump and driver adapter frames and the compartment cast or forced as an integral structurally seamless frame between pump and driver. The driver adapter frame radially surrounds and covers impeller axial adjustment studs and reference nuts at the bearing housing, for protection. The combination frame of the present invention provides a stronger structural integrity than the multi-component frames of the prior art which allows for more precise alignment of the coupling between motor and pump which reduces vibration.

  • Patent number: 5213480
    Abstract: A small wheelable line striper is provided with a gasoline engine powered pump which has an outlet designed for direct immersion into a container of paint or other coating material. The gasoline engine and pump are mounted on a pump frame which is attached to two telescoping posts so that the pump and engine may be lifted upwardly out of the bucket of paint. The pump frame is biased upwardly by a nitrogen gas spring which provides an upward force slightly greater than the weight of the engine and pump so that the pump may be lifted automatically. Latches are provided to latch the pump and engine in either the upward or downward positions.

  • Patent number: 5030346
    Abstract: The pump includes a discharge head having a pair of axially spaced end walls defining in part an annular chamber therebetween. The tank includes a housing in communication with a liquid outlet conduit. By seating the discharge head in the tank housing, an annular pump discharge chamber is defined with the housing and between the end walls of the pump. Clean coolant from the suction side of a filter disposed in the tank flows through the pump inlet and discharge head into the tank outlet conduit for delivery to machine tools. The pump is driven through a releasable coupling by an electric motor disposed above the tank mounted for movement between operative and out-of-the-way positions whereby the pump may be readily removed from and reinstalled in the tank without disconnection or connection of pipe fittings within the tank. Alternatively, a submersible electric motor may be provided.

  • Patent number: 5011368
    Abstract: A vacuum pump of the type having a Gaede channel, the pump comprising a stator (1) and a rotor (2) driven to rotate inside the stator, the stator including a suction inlet (12) and a delivery outlet (13). The active portion of the rotor situated between the suction inlet and the delivery outlet is hemispherical in shape (9) and is disposed inside a cavity (10) of the stator which is likewise hemispherical in shape. The axis .delta. of said rotor coincides with the said axis of the hemispherical cavity of the stator. Suction takes place at the large circle end of the hemispherical rotor via radial clearance j.sub.a between the rotor and the stator, and delivery takes place at the pole end of the hemispherical rotor. An adjustment distance piece (14) for axially positioning the rotor (2) relative to the stator (1) is provided so that the radial delivery clearance j.sub.r is smaller than the radial suction clearance j.sub.a.
