Abstract
A drill rig may include a motor connected to a piston-diaphragm pump configured to: apply a force to a fluid in a cylinder of the piston-diaphragm pump by moving a piston in the cylinder, the fluid filling a void inside the cylinder between a head of the piston and one side of a diaphragm; transfer the force from the fluid across the diaphragm to a drilling mud by flexing the diaphragm, where the drilling mud is separated from the first fluid; and cause a flowrate of the drilling mud through a value connected to the cylinder via a high-pressure piping system into the borehole. The drill rig may direct the mud through a kelly and a pipe to a bottom of the wellbore, force the mud through nozzles located near a bit, rotate the bit, and returning the mud through an annulus to the surface.
