An electrical submersible pump assembly has a motor lead extending alongside the pump housing to the motor for supplying electrical power to the motor. At least one standoff wedges between the pump housing and the motor lead. The standoff has a channel in which the motor lead is received. The standoff has legs extending inward from the channel into contact with the pump housing. The legs space the channel of the standoff from the pump housing by a gap to enable well fluid flow between the motor lead and the pump housing.

Method to assemble a water pump with an impeller driven by an electrical machine comprising a housing cap and a volute with an inlet and an outlet and a boot hosting a stator and a rotor of the electrical machine and an electronic board mounted at the side apart from the impeller and covered by the cap housing, the boot having a radial extending rim comprising at least slots defined by the following steps: connecting the volute to the boot by inserting axial hooks in the boot's slots, twisting the volute versus the boot to fix the axial hooks, inserting radial hooks of the cap housing in the same slots.

A system and a method for removing a portion of an electric submersible pump power cable conduit housing are provided. The method may include cutting a conduit housing of the conduit, sliding the cut conduit housing off the conduit, and squaring an end surface of remaining conduit housing. The cutting of the conduit housing is not a through cut and the sliding of the cut conduit housing off of the cut conduit is performed with a conduit housing spreader. The system may include a conduit housing cutter for cutting partially through the conduit housing of the conduit and a conduit housing spreader for pulling the portion of the conduit housing apart from a remaining conduit housing. In addition, the system may include a squaring tool to square an end surface of the remaining conduit housing relative to an axis of the conduit.

A pump comprising a housing, a motor disposed within the housing, and an impeller driven by the motor and configured to create a low-pressure region to draw fluid into the housing. The pump further includes a battery electrically coupled to the motor and configured to selectively supply electrical current to the motor and a controller operable to control operation of the motor.

In this motor pump unit comprising an impeller (1) surrounded by a volute (2) and mounted on the output shaft (3) of an electric motor (4) surrounded by a housing (5) which is closed on the side opposite the impeller (1) by a cover (6), an extension (7) is interposed between the cover (6) and the housing (5) and a sensor (11) for sensing a property of the impeller (1) is housed in the extension (7).

A motor vehicle fuel pump cover system. The system protects a connection between a fuel line and a fuel pump. The cover includes a cover for a fuel pump. Both parts of the cover define a raised wall around the connection. The cover also includes a second cover. The second cover is hinged to the first cover and forms a dome to cover the connection. The dome has an interior peripheral surface that covers the raised wall to thereby form a chamber protected against foreign matter infiltration. In another aspect, the disclosure relates to a motor vehicle fuel pump having an exterior fuel connection protected by the cover system against damage caused by foreign matter.

A hanging bracket for supporting a suspended apparatus and a control unit housing includes a base having a first end and a second end. The first end includes a first surface and a first screw boss therethrough, and the second end includes a second surface and a second screw boss therethrough. The bracket also includes a support portion vertically spaced from the base, where the support portion adapted to support the suspended apparatus, and a neck extending between the base and the support portion. At least the first surface of the first end of the base, the second surface of the second end of the base, and the first and second screw bosses collectively form an interface configured for juxtaposition with complementary surfaces and screw holes of the control unit housing.

A device for the control and management of at least one electric pump, comprising: an element for the actuation of the device, a user interface, connected to the actuation element.

The device comprises PLC data link means.

An electric pump comprising: a containment shell, a wet section, comprising an intake portion, a delivery portion and one or more impellers keyed on a shaft, the one or more impellers being interposed between the intake portion and the delivery portion, an electromechanical section, comprising motor means for the movement of the shaft, an electronic section, comprising a compartment inside which an to actuation and control assembly is contained, the actuation and control assembly having an electrical board.

The actuation and control assembly comprises communication means of the NFC type.

A centrifugal electric pump assembly, comprising a wet section, which comprises inside it a liquid and/or solid scale remover substance in a position that at least potentially communicates with the wet section.
