NOV FD-1000 mud pump

The FD-1000 is a 1,000 horsepower triplex mud pump from the Continental-Emsco FD line, now sold under NOV. It circulates drilling fluid the same way a 12-P-160 does, at a lower horsepower. NOV’s current page rates it at 1,000 horsepower at 140 strokes per minute, with a maximum liner and stroke of 6¾ by 10 inches.

This is a pump for a smaller land rig or a workover package that does not need 1,600 horsepower of circulation. One or two of them is a typical setup. It will not substitute for a 12-P-160 on a rig whose pumps, motors, and discharge iron are built for 1,600 horsepower and a 12-inch stroke.

The FD family shares a naming pattern, and the number is the horsepower class: FD-1000 is 1,000, FD-1600 is 1,600. Older FD manuals describe liner and stroke pairs that do not always match the current product page. The nameplate and the stroke length are what decide whether liners from another FD pump will fit.

Match the stroke and the maximum liner to the expendables you already own before you treat two FD pumps as the same. Ask for the fluid-end pressure rating. Horsepower alone does not tell you if the pump can hold the pressure on the well.
