NOTE:
Power absorbed by a pump is almost directly proportional to
discharge rate. However this relationship is true only for radial
discharge centrifugal pumps.
MUD PUMPS:The main component of fluid circulating equipment for rotary
drilling is mud pump. It provides the driving force that sends the fluid
through the route that must travel.
The PT series mud pumps are horizontal, triplex, single acting,
piston pumps. These pumps will provide a uniform flow over a wide
pressure-volume range to meet any drilling requirement within its size
capability. These pumps are categorized by the input HP rating. Detailed
specifications of M/S BHEL/ M/S BPCL make mud pumps are given
below.
