Abstract: An apparatus and method according to which a fluid, such as a fracturing fluid, is pressurized. The apparatus includes a motor that produces a first rotational output including a first angular velocity, a pump operably coupled to the motor, the pump comprising a fluid end and a power end operably coupled to the fluid end, and a transmission operably coupled between the motor and the pump. The transmission receives the first rotational output as a first rotational input, the first rotational input including the first angular velocity, and converts the first rotational input into a second rotational output, the second rotational output including a second angular velocity. The power end receives the second rotational output as a second rotational input, the second rotational input including the second angular velocity. In some embodiments, the transmission is directly connected to, or part of, the pump and the motor.

Abstract: A valve seat includes a generally cylindrical body that defines a bore extending axially therethrough and has an outer surface. An enlarged diameter portion extends axially from the generally cylindrical body and defines a shoulder surface and an annular surface disposed opposite the shoulder surface; the annular surface is configured to form a seal with a displaceable portion of a valve. An annular notch is formed in the outer surface of the generally cylindrical body, and it extends a distance from a shoulder surface. The annular notch decouples a stiffness of the enlarged diameter portion to thereby increase a radial compressibility of the generally cylindrical body. An annular channel is formed in the outer surface of the generally cylindrical body and is disposed axially below the annular notch. The annular channel is configured to receive a hydraulic fluid to compress radially the generally cylindrical body.
