The MPowerD™ backpressure pump is a necessary component to supply and maintain backpressure during low-flow and pumps-off events. Our managed pressure drilling (MPD) backpressure pump is designed to operate with water-based, oil-based, or synthetic-based mud.

The backpressure pump is a 185 horsepower, 5-in. stroke pump. It has an intermittent-duty, single-acting well service piston/plunger pump equipped with a forged alloy steel mono-block fluid end. It is rated at pump speeds up to 450 rotations per minute (RPM) with a maximum discharge pressure of up to 10,000 psi. NOV’s backpressure pump can be equipped with multiple external gear reduction units.
