A mobile power supply device and method for energizing a sump pump in a sump pit during a power outage, and a mobile power supply device and method for energizing a sump pump secured to a bottom portion of the device. The device includes an enclosure similar to a dolly that is manufactured from plastic or similar non-electrically conductive material to minimize weight to enable the manual lifting and pulling of the mobile power supply device, and to promote safety by reducing the chance of an electrical short circuit when supplying electrical power to a sump pump. The enclosure includes a carrying handle and a relatively large dolly handle that cooperate with castors attached to a bottom portion or bottom surface of the enclosure. The castors promote manual movement of the device upon a substantially horizontal surface or up and/or down stairs leading to a sump pump in a sump pump well or pit in a basement.

An automatic fluid pump includes a pump body having a liquid channel and a mounting channel, the liquid channel having an inlet and an outlet and connected to a suction pipe and a delivery hose, respectively. A motor fan is disposed at a lower end of the suction pipe. A power controller is coupled to the pump body and circuit-connected to a battery, a terminal plate, and a switch. A valve case is coupled to the mounting channel in the form of a hopper formed at a lower end thereof with an inclined portion having an air hole. A valve case cap is coupled to the valve case. A main check valve is disposed on a lower surface of the valve case cap to open/close the through-holes. An auxiliary check valve is vertically moved up and down between the mounting channel and the air hole to open/close the air hole.

A portable water filtration apparatus has a top panel, a mounting surface, an electric pump mounted to the mounting surface, at least one filter, and at least one filter housing coupled to the top panel, with the at least one filter filtering water from the pump. The portable filtration apparatus has a housing, such as a bucket, to fully contain the components and which may be used for collecting either filtered or unfiltered water.

Apparatus for an electrically powered fluid feature comprises a unit including a fluid pump and a rechargeable power source arranged to provide power to the pump for operation of the fluid feature. The power source may be rechargeable via electrical contacts. The unit may comprise upper and lower housing portions that are separable to allow cleaning, replacement or recycling of components. The unit may be removably installed in a reservoir, which is supported within a container by adjustable supports.

An electric driven hydraulic fracking system is disclosed. A pump configuration includes the single VFD, the single shaft electric motor, and the single hydraulic pump mounted on the single pump trailer. A controller associated with the single VFD and is mounted on the single pump trailer. The controller monitors operation parameters associated with an operation of the electric driven hydraulic fracking system as each component of the electric driven hydraulic fracking system operates to determine whether the operation parameters deviate beyond a corresponding operation parameter threshold. Each of the operation parameters provides an indicator as to an operation status of a corresponding component of the electric driven hydraulic fracking system. The controller initiates corrected actions when each operation parameter deviates beyond the corresponding operation threshold. Initiating the corrected actions when each operation parameter deviates beyond the corresponding operation threshold maintains the operation of the electric driven hydraulic fracking system.

An electric driven hydraulic fracking system is disclosed. A pump configuration that includes the single VFD, the single shaft electric motor, and the single hydraulic pump that is mounted on the single pump trailer. A pump configuration includes a single VFD configuration, the single shaft electric motor, and the single shaft hydraulic pump mounted on the single pump trailer. The single VFD configuration converts the electric power at the power generation voltage level distributed from the power distribution trailer to a VFD voltage level and drives the single shaft electric motor to control the operation of the single shaft electric motor and the single hydraulic pump. The VFD voltage level is a voltage level that is required to drive the single shaft electric motor. The VFD configuration also controls operation of the auxiliary systems based on the electric power at the auxiliary voltage level.

A pump for non-flammable liquids has an improved mounting for the motor which facilitates the relatively quick and easy removal of the motor from the pump. The pump has a main body which is hollow and cylindrical. A motor housing is connected to the main body by threads at a first end and has a removable end cap on its second end. The electric motor is located in said motor housing and secured when the end cap is on the motor housing. An electronics housing has a battery adapter plate, a switch, and a discharge port, and encloses wires and electronics such that the motor pumps the liquid from the end cap, through the motor housing and the main body, and out of the discharge port when the switch is turned on.

An electric driven hydraulic fracking system is disclosed. A pump configuration that includes the single VFD, the single shaft electric motor, and the single hydraulic pump that is mounted on the single pump trailer. A power distribution trailer distributes the electric power generated by the power generation system at the power generation voltage level to the single VFD and converts the electric power at a power generation voltage level to a VFD voltage level and controls the operation of the single shaft electric motor and the single hydraulic pump. The power distribution trailer converts the electric power generated by the power generation system at the power generation level to an auxiliary voltage level that is less than the power generation voltage level. The power distribution trailer distributes the electric power at the auxiliary voltage level to the single VFD that controls an operation of the of the auxiliary systems.
