Feb 01, 2018  The positive displacement pumps typically used on drill rigs pump water in proportion to how fast they are spinning; the faster they spin the more they pump. The amount of water pumped will be nearly the same over a very large pressure range and for this reason, water pressure does not tell the driller anything about how much water is flowing.
