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 pump housing (2) includes a circumferential wall (3), a pump casing (20) and a shaft cover (40). The pump casing (20) is attached to the circumferential wall (3) by a plurality of connection elements. The pump casing (20) includes a central opening (27) to form an axial supply (14) of the pump housing (2) for material to be pumped. The circumferential wall (3) closes the pump housing (2) along its outer circumference. The pump (1) includes a plurality of connection elements (22) connecting the pump casing (20) to the circumferential wall (3). The connection elements (22) are positioned in groups along the circumference of the pump housing (2), wherein the groups are regularly distributed along the circumference of the pump housing (2).

A liquid cooling multi-pumping unit comprising a main body and first and second pumps arranged in series is provided. During operation, cooling fluid is sucked via a cooling fluid inlet into a first fluid chamber and then into a first central chamber opening to a plurality of curved blades of a first impeller assembled in a first pump chamber. From there, the cooling fluid travels and is sucked through a fluid distribution channel into a second fluid chamber and then into a second central chamber opening to a plurality of curved blades of a second impeller assembled in a second pump chamber, before exiting through a fluid outlet. The series arrangement of the first and second pumps increases head pressure, and provides sufficient liquid flak in the case where one liquid cooling pump fails. Additionally, lower energy consumption is achieved die to the lower operating speeds required.

An electric submergible pumping system that includes a pump having a pump discharge; a motor; a power crossover assembly including a first top flange having a generally circular opening in the center, an upper tubular portion connected to the first top flange portion, an intermediate tubular portion including two generally rectangular shaped windows for intake suction for production fluids, a lower tubular portion having a hollow space in a center portion, and a first lower flange having a circular shape connected to the lower tubular portion. The system also includes a crossover base disposed at a lower part of the power crossover assembly, the crossover base including a base neck, a guide tube, a conductor terminal, a second top flange, and a second lower flange.

A centrifugal electric pump includes a motor casing, containing in turn, an electric motor with a transmission shaft and a hydraulic part. The transmission shaft is connected to at least one impeller present disposed in the hydraulic part. The motor casing is provided internally with a housing in which the electric motor is accommodated. An external surface of the housing defines a cooling surface adapted to be flowed over by pumping liquid that arrives from the hydraulic part. The cooling surface is provided with a covering that is resistant to oxidation. The covering is constituted by a hydraulically isolating sheath, which is contoured to affect the cooling surface.

A pump for pumping liquids containing entrained solids. The pump includes a volute surrounding an impeller comprising vanes that are self-cleaning. The outer surfaces of the vanes are coplanar and define a first plane and have a leading edge. The volute includes a planar mating surface defining a second plane parallel to the first plane of the rotary impeller. The planar mating surface is proximate to the outer surfaces of the vanes and includes a plurality of channels extending radially from the inner perimeter to the outer perimeter thereof. Each channel includes a forward edge in the direction of impeller rotation. The channels are oriented such that when the impeller is rotated within the volute, for any vane, the leading edge of the vane traverses each channel progressively from the inner end of the channel to the outer end of the channel.

A user interface may be communicatively coupled with a fluid-moving pump and may include at least two interactive regions for receiving user input to control the fluid-moving pump. The user interface may be attached to the fluid-moving pump using a mounting cover and an attachment bracket that can allow attachment or positioning of the user interface relative to the fluid-moving pump via a turn motion or other suitable methods. In other examples, the user interface can be mounted on a wall or other surface.

A circulation pump assembly, with a wet-running electrical drive motor (4), includes a pump casing (6) as well as a motor housing (22) which is connected to the pump casing (6). The motor housing (22) is a combined stator and electronics housing that accommodates a stator (18) of the drive motor (4) as well as motor electronics (34). The motor housing (22), at a first axial end (24) facing the pump casing (6), is closed by an air gap sleeve (16) of the drive motor. The motor housing (22), at a second axial end (26) which is away from the pump casing (6), includes an opening (42) closed by a cover (28). An interior of the motor housing (22), in a region adjacent the first axial end (24), is filled with a potting mass (40) surrounding the stator (18) and the motor electronics (34).

A pressure assisted washer or pressure washer with hose reel and motor pump assembly. The hose reel defines a bore in which a motor pump assembly is disposed. The hose reel comprises a cylinder having an aperture through which pressurized fluid can be accessed through a coupling in fluid communication with a pump. The pump has a rotating collar.

A water pump apparatus is provided having a plurality of modular components, which allows for construction of various configurations of the water pump apparatus depending on specific vehicle requirements. The water pump apparatus modular components include a pump housing with a fluid chamber formed therein, a bearing housing for attachment to the pump housing, and a thermostat housing for connecting to the bearing housing and the pump housing. A method for forming modular components for assembling a water pump apparatus for use in an internal combustion engine is also provided.
