Pumps in the Gas and Oil Industry Adapted from Information by DAE Pumps Pumps are necessary components inside an oil drilling rig. They’re designed to accelerate fluid transferring from one location to another. Let’s explore the different types of pumps used by gas and oil operations, their primary function, and the pros and cons of each model. Centrifugal Pump - The most common type of pump in the gas and oil industry is the centrifugal pump. These pumps contain one or more impellers. Fluid is drawn into the suction end of the pump and then, through centrifugal force, it is forced out of the dis- charge end. This design allows the pumps to be used for a wide range of applications and are preferred for processes han- dling low-viscosity liquids and high flow rates. Oil Pump - A standard oil pump mechanically lifts liquid out of the well when there isn’t enough ground pressure to force it to the surface. They are used in area s where oil is abundant, but the groun d needs help releasing it. Depending o n the depth and weight of the oil, thes e pumps are capable of delivering one t o ten gallons of fuel with every stroke , known as a “walking beam.” Positive Displacement Pump - I n contrast to centrifugal pumps, positiv e displacement pumps don’t use impeller s to move fluid, but rather, rotating or recip - rocating parts to push / transport liquids . This creates pressure, which moves th e liquid to its destination. Positive displace - ment pumps are perfect for higher viscos- ity liquids transported at a lower flow rate s and are not typically used in high-flo w situations. These pumps are also more compact , which increases the high-pressure ratio , making them one of the most efficien t types of pumps. Although they are afford - able and efficient, positive displacemen t pumps require extensive maintenance , partly due to mechanical part failures. Oil Transfer Pump - An oil transfe r pump transfers glycol from the well to a holding tank during refinement. Thes e pumps work by creating a variation i n pressure, pushing the fluid from one loca - tion to another. Industrial-scale slurr y pumps can operate on electric, solar , hydraulic, or gas power. Since the compo- nents are built using corrosion-resistan t metals capable of withstanding hazardou s environmental conditions, transfer pump s are generally used to move flammable o r corrosive liquids like oil, gas, or chemicals . The high volume of activity also mean s they require extensive maintenance an d repairs. Diaphragm Pump - A diaphrag m pump is a type of positive displacemen t pump which uses both a valve and a An oil pump in Utah’s Red Rock Desert.
