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.

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. The single VFD converts the electric power of at least 13.8 kV to a VFD rated voltage level of at least 4160V and drives the single shaft electric motor at the VFD voltage level of up to 4160V to control the operation of the single shaft electric motor and the single hydraulic pump. The single shaft electric motor drives the single hydraulic pump with the rotation at the rated RPM level of at least 750 RPM. The single hydraulic pump continuously pumps the fracking media into the well at the HP level of at least 5000 HP. The single hydraulic pump operates on a continuous duty cycle to continuously pump the fracking media at the HP level of at least 5000 HP.

Certain embodiments of the present application relate to a variable frequency drive (VFD) cabin for a pump configuration including a mobile trailer on which the VFD cabin is to be mounted. The VFD cabin generally includes a medium-voltage VFD and a ventilation system. In certain embodiments, the ventilation system is configured to generate an overpressure condition within the cabin to discourage the entry of dust and debris into the cabin. In certain embodiments, one or more components of the medium-voltage VFD are coupled to the floor of the cabin via a vibration damping system. In certain embodiments, the VFD cabin may be directly coupled to a chassis of the mobile trailer without an intervening suspension being provided between the VFD cabin and the chassis.

The present disclosure relates to a sampling pump configured for use in a wellbore for pumping liquid collecting in the wellbore. The sampling pump has a pump component including a motor and an outer housing configured to be inserted into the well bore. The outer housing has an inlet and an outlet. A fluid sensor detects when the inlet of the outer housing is positioned in the liquid in the wellbore. A flexible electrical cable assembly supplies power to the motor and the fluid sensor, and also communicates with the motor and the fluid sensor. A user control panel communicates with the flexible electrical cable and enables a user to control on and off operation of the DC motor from the control panel. The user control panel also has a component which is responsive to signals from the fluid sensor to indicate when the inlet is at least partially submerged in the liquid within the wellbore, as the pump is lowered into the wellbore.

A water pumping control device may include a primary power source and a secondary power source. The primary power source may be configured to provide a primary power input to a processing unit, and the secondary power source may be configured to provide a secondary power input to the processing unit. A primary pump and a secondary pump may be in communication with the processing unit, and the primary pump and the secondary pump may each be variable in speed. The primary pump and the secondary pump may each be in fluid communication with a sump so that when a pump is activated, the pump may remove water from the sump. A water level sensor may be in communication with the processing unit, and the water level sensor may be configured to provide a water level input describing a water level in the sump to the processing unit.

A system and method for a battery-operated back-up sump pump. The method includes providing a back-up sump pump kit including the back-up sump pump, a first check valve, a second check valve, and a joint. The method also includes cutting a discharge pipe extending from a primary sump pump in a sump pit in order to create a first end open toward the primary sump pump that remains in the sump pit and a second end open toward the discharge pipe leading out of the sump pit. The method further includes installing the first check valve at the first end of the cut discharge pipe, installing the second check valve downstream from the battery-operated back-up sump pump, coupling the first check valve and the second check valve to the joint, and coupling the joint to the second end of the cut discharge pipe.

An integrated, portable, battery-powered, variable-pressure electric liquid pump and power emergency station including one of one or more wired sensors and one or more wireless sensors that provide at least one of real-time heat, water, smoke, barometric, wind speed, humidity, distance, or seismic data, wherein the emergency station includes at least one hardware processor; and one or more software modules that, when executed by the at least one hardware processor, provide at least one of the emergency station, one or more users, and one more ancillary devices with at least one of real-time heat, water, smoke, barometric, wind speed, humidity, distance, and seismic data from at least one of the one or more wired sensors and the one or more wireless sensors.

A sump pump system having a primary pump, a fluid level sensor, and a primary controller electrically connected to the primary pump for activating the pump when the fluid level sensor indicates a predetermine fluid level has been reached, the primary controller having a primary interface for communicating with a secondary pump. In some forms, the system includes a secondary pump having a secondary controller electrically connected to the secondary pump and having a secondary interface, the primary and secondary interfaces allowing the primary and secondary pump controllers to communicate with one another and allowing at least one of the primary and secondary pump controllers to assume control of both the primary and secondary pump.
