Abstract (en)

[origin: US2017184089A1] A submersible pumping system includes an electric motor and a pump driven by the electric motor. The pump includes a rotatable shaft driven by the motor, one or more piston assemblies configured for linear reciprocating motion and a mechanism for converting the rotational movement of the shaft to linear reciprocating movement in the piston assemblies. In one aspect, the mechanism for converting the rotational movement of the shaft includes a tilt disc assembly. In another aspect, the mechanism for converting the rotational movement of the shaft includes a camshaft assembly.
