One embodiment provides a remotely controllable gas engine replacement device including a housing, a battery receptacle coupled to the housing, the battery receptacle configured to removably receive a battery pack, a motor located within the housing, a power take-off shaft receiving torque from the motor and protruding from a side of the housing, a power switching network configured to selectively provide power from the battery pack to the motor, and one or more remote control device interfaces configured to communicate with the remote control device. The remotely controllable gas engine replacement device also includes an electronic processor coupled to the power switching network and the remote control device interface. The electronic processor configured to control the power switching network to rotate the motor, receive a control signal from the remote control device, and execute a responsive action to the control signal from the remote control device.

A system for removing fluids from a subterranean well. The system includes a housing comprising a hollow cylindrical body, the hollow cylindrical body having a first end and a second end; a pump for removing fluids from the subterranean well, the pump positioned within the hollow cylindrical body; and a battery-powered driver for driving the pump, the driver positioned within the hollow cylindrical body; and an apparatus for releasably securing and sealing the first end of the housing. A method for removing fluids from a subterranean well is also provided.

An inflator tool includes a handle portion extending between a battery receiving portion and a tool head portion. The handle portion defines a longitudinal axis. The tool head portion includes an air inlet, a compression chamber, and an air outlet. A motor is at least partially supported within the handle portion and includes an output shaft. The air inlet defines an inlet axis, and the air outlet defines an outlet axis. The longitudinal axis is disposed at an oblique angle relative to each of the inlet axis and the outlet axis.

A blower for use to provide combustion air to a fire (e.g., to assist in the lighting of a fire). The blower may include a cylindrical housing having an inlet opening and an outlet opening with a bore extending between the inlet and the outlet. A fan and power source may be provided to induce air flow from the inlet opening and through the bore such that air is expelled from the outlet opening. The outlet air exiting the outlet opening may travel in a direction substantially parallel with a central axis of the cylindrical housing. The blower may be supported by an infinitely adjustable flexible member that may be manipulated to position the blower with respect to the fire to provide outlet air to the fire. The flexible member may be engaged with a clip to attach the blower to a structure adjacent to the fire.

A pump system comprising a primary AC pump, a control unit having a wireless communication module, and a back-up battery for powering the control unit. The wireless communication module is configured to communicate via a primary wireless connection and communicate via a secondary wireless connection. Additional pump system components and various methods relating to same are further disclosed herein.

A pumping device for liquids is described which comprises a tank for liquids, from which a feeding pipe of a pump with a solar panel draws. The tank consists of a supporting frame with tubular uprights and upper and lower horizontal connection lengths, which supports and surrounds a flexible bag for containing liquids and has an upper connection crossbar of the upper horizontal lengths of the supporting frame, on which the pump with solar panel is mounted. The bag has a lower filling hole or mouth, in which the feeding pipe can be inserted and an overflow hole made in the upper of part of its side wall in position lower than said mouth.

A submersible pump and related methods are disclosed herein. The pump assembly includes a pump housing and a motor with a motor housing/cap and an output shaft connected to an impeller that is disposed in a volute. In some forms, a separate power circuit compartment is formed integral to one of the pump housing and/or volute to store power circuitry that allows a DC pump to be used and powered by AC voltage. In other forms, the power circuit compartment is formed separate from the pump assembly and fastened or connect to the pump assembly. In preferred forms, the power circuit compartment is positioned relative to the pump assembly at a point where it will be maintained at least partially within the fluid surrounding the pump to dissipate heat from the power circuit. Numerous methods are also disclosed and contemplated herein.

A system and device for enhancing the cooling of items in a cooler by circulating fluid substance within the cooler. The device is waterproof and comprises a power source operably coupled to a controller and a motor. The controller is configured to transmit power to the motor. A rotating mechanism is operably coupled to the motor such that the motor provides rotatable power to the rotating mechanism. The rotating mechanism is positioned on the device between a first position and a second position. An inlet is positioned at or near the first position and an outlet positioned at or near the second position. The device is configured for a fluid substance to enter the device through the inlet and exit the device through the outlet. The fluid substance exits the device at a higher rate than that of entry. The inlet is positioned at a lower portion of the device.

A high-capacity pump fabricated with improved motor cooling and corrosion resistant components and powered by a variable-speed brushless DC motor suitable for use with a wide variety of applications. A brushless 12V DC motor is controlled by a manual and wireless variable speed control means to provide unparalleled flow control. The motor is contained within the housing in a sealed cavity in the housing, wherein the cavity is filled with mineral oil which maximizes heat transfer to facilitate motor cooling. A PVC impeller is contained within a PVC section of the housing thereby creating a corrosion resistant impeller section. The pump of the present invention has achieved improved performance over known pumps and is capable of delivering 4,500 gallons per hour (GPH) at 6 feet of head pressure, while only drawing 30 amps at 12 Volts DC. Wireless remote control of the pump is achieved via a wireless enabled device.
