Oil & Gas

Pumps are one of the mostly used equipment in oil, gas and petrochemical industry. Pumping equipment is extremely diverse, varying in type, size, driver and materials of construction. Pumps are classified into two fundamental types based on the manner in which they transmit energy to the pumped liquid: kinetic or positive displacement. In a kinetic type, a centrifugal force of the rotating element, called an impeller, force kinetic energy to the fluid, moving the fluid from pump suction to the discharge. On the other hand, positive displacement uses the reciprocating action of one or several pistons, or a squeezing action of meshing gears, lobes, or other moving bodies, to displace the liquid from one area into another.
