Industrial pumps are essential equipment required for all stages of oil and gas transportation. They help to transfer media from one point to another. For example, pumps can be used to transfer crude oil from storage tanks to pipelines, and mud pumps are used to circulate drilling mud through the annulus of the drill bit and back to the storage tanks for repurification. In oil and gas operations, process fluids range from simple to difficult. We can recommend the most suitable pump for you depending on the nature of the substance you wish to transfer and the flow rate required.
Industrial pumps used in the oil and gas industry can usually be divided into three categories according to pump design and construction, including centrifugal pump, screw pump and gear pump.
1. Centrifugal Pump
Centrifugal pumps are the most popular pumps in the oil and gas sector. Centrifugal pumps draw fluid into the inlet of the pump and use centrifugal force to propel it through the discharge section, which is accomplished by the rotation of the pump impeller.
The primary application for single-stage centrifugal pumps is the high-flow transfer of low-viscosity fluids. Typically, they are used as part of a larger pump network that also includes other centrifugal pumps, such as water injection pumps for secondary oil and gas recovery or horizontal multistage pumping units for transferring crude oil.
2. Screw Pump
A screw pump is a type of positive displacement pump and is also known as an eccentric screw pump or cavity pump. It transfers fluid by means of the progress, through the pump, of a sequence of small, fixed shape, discrete cavities, as its rotor is turned.The screw oil pumps are used in high viscosity applications or if blending the of the pumped fluid is not desired.
Progressive cavity pumps are also considered constant flow pumps since at a given speed, the flow rate is relatively constant despite the system pressure. Flow slippage is normal at higher pressures. A relief valve is an essential part of any progressive cavity pump discharge piping system to prevent overpressuring of the pump and piping system.
3. Gear Pum
Gear pumps pump fluids by displacement through the meshing of gears. One of the most popular designs of positive displacement pumps for moving industrial fluids is the gear pump. The gear pumps are also frequently used in applications involving chemical transfer of highly viscous fluids. In applications involving the chemical transfer of highly viscous fluids, gear pumps are also frequently utilized. There are two primary variants: timing gears that drive the internal gear set or external gear pumps that use two external spur gears.The external gear pumps can pump non-lubricating fluids because the internal gears do not come into contact with one another. The internal mating gear of an internal gear pump is driven by a shaft-driven driving gear. Gear pumps pump a predetermined amount of fluid with each rotation since they are positive displacement pumps.
Gear pumps are typically utilized for clean fluids since the fluid being pumped moves between the close gear tolerances. The discharge piping system requires a relief valve in order to prevent overpressurization of the pump and pipes.
