Abstract: A syringe assembly for a hydraulic fracturing system includes a syringe having a material chamber, a base fluid chamber, and a piston. The material chamber is configured to be fluidly connected to a fluid conduit. The piston retracts to draw material into the material chamber. The piston extends to push the material into the fluid conduit. The syringe assembly includes a diverter fluidly connected to the base fluid chamber and moveable between first and second positions. The first position of the diverter fluidly connects the base fluid chamber to a base fluid reservoir of the hydraulic fracturing system and fluidly disconnects the base fluid chamber from an outlet of a frac pump of the hydraulic fracturing system. The second position of the diverter fluidly connects the base fluid chamber to the outlet of the frac pump and fluidly disconnects the base fluid chamber from the base fluid reservoir.

Abstract: A fluid delivery device for a hydraulic fracturing system includes a fluid conduit having a fracking fluid outlet configured to be fluidly connected to a well head for delivering a fracking fluid to the well head. The fluid conduit includes a base fluid inlet configured to be fluidly connected to the outlet of a frac pump such that the fluid conduit is configured to receive a flow of base fluid from the frac pump. An injection system is fluidly connected to the fluid conduit downstream from the base fluid inlet and upstream from the fracking fluid outlet. The injection system is configured to be fluidly connected to a material source. The injection system is configured to inject at least one material of the fracking fluid from the material source into the fluid conduit downstream from the frac pump to generate the fracking fluid within the fluid conduit.

Abstract: According to one aspect, an apparatus adapted to be connected to a component that is part of a pump system or a manifold trailer includes a block defining opposing first and second exterior surfaces. In one aspect, the block includes a recess formed in the first exterior surface and extending towards the second exterior surface, and an opening formed in the second exterior surface. In another aspect, the apparatus also includes an electronic identifying device at least partially accommodated within the recess, the device including a first portion having data stored thereon that provides identification of the component. In one aspect, the electronic identifying device further includes a second portion having data stored thereon that provides one of: information associated with certification of the component; and identification of the pump system or the manifold trailer of which the component is a part.
