Abstract
A progressing cavity pump operated by a motor is provided. In one embodiment, a system includes a motor, a progressing cavity pump having a rotor and a stator, and a fluid coupling that connects the motor to the progressing cavity pump. The fluid coupling includes an input turbine and an output turbine disposed within a housing. The motor is connected to the input turbine of the fluid coupling and the rotor of the progressing cavity pump is connected to the output turbine of the fluid coupling to enable the progressing cavity pump to be operated by the motor via the fluid coupling to pump fluid through the progressing cavity pump. Additional systems, devices, and methods are also disclosed.
