A computer-controlled motorized pump system is provided. A generator is mechanically connected to a power takeoff. A first controller receives AC power from the generator and converts the AC power to DC power and provides DC power to a computing system that has one or more processors and one or more computer-readable hardware storage media and a user interface. A second controller is directly coupled to the first controller and provides AC power to a motor. The motor is mechanically connected to a pump, and the motor is in communication with, or controlled by, the computing system.

The invention uses a multiplicity of stacked storage racks at least one of which is inclined wherein each rack is equipped with a powered mechanism for deploying and retracting a large diameter drain hose or vent hose. The at least one storage rack that is inclined is used to store a large diameter drain hose such that a flex is formed in the stored hose which is at a lowered elevation than the uncoupled end of the stored hose. By this means a stored large diameter drain hose can transport, and not spill, fluid from a previous use.

A tanker truck offloading system and method. The tanker truck offloading system includes a manifold in fluid communication with a tank and a plurality of tanker truck offloading stations, a tanker truck coupling at an open end of the manifold at each of the plurality of tanker truck offloading stations, and an air separator in fluid communication with the manifold.

A collection tank for use in a vacuum operated earth reduction system, the collection tank comprising a closed first end, an open second end defining a tank sealing flange and a body extending between the closed first end and the open second end. An internal chamber defined by the body, the closed first end and the open second end has a door coupled to the open second end and is configured to releasably seal the open second end. An automated door closer is coupled to a center of the door, wherein the automated door closer provides a closing force at the center of the door so that the closing force is equally distributed about a periphery of the door to seal the door against the tank sealing flange.

A multi-tank recirculating chemical fluid storage system for receiving and managing one or more fluids at multiple stage frac jobs. The multi-tank recirculating chemical fluid storage system comprises a support frame, a chemical tank, and a water manifold. The multi-tank recirculating chemical fluid storage system is configured to recirculating and agitate fluids in the chemical tank with pumps to reduce any settlement and keep precipitates to a minimum. The multi-tank recirculating chemical fluid storage system comprises a plumbing assembly, one or more pumps, and a drive system. The support frame comprises a front end, a rear end, a first side, and a second side.

A fuel transport sensor system for precise loading and unloading of fuel for transports includes a transport computer configured to be coupled to a fuel transport having a plurality of fuel compartments. Each of a plurality of load head sensors is in operational communication with the transport computer and coupled to one of a plurality of load heads. A load arm sensor coupled to a load arm and the load arm sensors communicate with the transport computer to track which fuel compartment is being filled with what fuel type. A pair of hose sensors coupled to a delivery hose confirm the delivery hose is connecting the load head with the correct fuel type for an in-ground storage tank before allowing a fire valve of the load head to be opened.

Transport vessel filling systems, methods and apparatus are described. Some embodiments include liquid fill nozzle assemblies. Some liquid fill nozzle assemblies are in fluid communication with a sprayfill standpipe. Some liquid fill nozzle assemblies include a plurality of liquid fill nozzle assemblies configured to extend to on one or both lateral sides of a vessel.

An agricultural product delivery applicator for delivering particulate product to a field. The applicator comprises a bin to hold the product, a pneumatic conveying system to provide an airflow, a metering system operably connected between the supply compartment and the pneumatic conveying system, and a rail system. The metering system meters product with the airflow to result in a mixed flow of airflow and product. The rail system includes first and second foldable rails.

A rising stem valve comprises a hollow valve body having a pair of ports defining a flow path through the valve body, a flange base through which one of the ports extends and a valve bonnet opposite the flange base. The valve includes a plunger/seal assembly able to be extended within the valve body to a first position for sealing the port in the flange base and to a second position for unsealing the port in the flange base. The valve also includes a locking mechanism for securing the plunger/seal assembly in the first position. The locking mechanism includes at least one cam lever attached to the valve body and a corresponding groove in a valve stem of the plunger/seal assembly.
