Types of Pumps used in Oil & Gas Industry

In the oil and gas industry, pumps are used for a variety of applications, including transferring fluids, such as crude oil and natural gas, between production wells and storage tanks or processing facilities. The selection of pumps for these applications involves considering a number of factors, including the type of fluid being pumped, the required flow rate and pressure, the operating environment, and the desired lifespan of the pump.



There are many types of pumps used in process industries, including chemical, pharmaceutical, food and beverage, and petroleum refining. The type of pump used in a particular process depends on the specific requirements of the application, such as the type and viscosity of the fluid being pumped, the required flow rate and pressure, and the operating environment. Some common types of pumps used in process industries include:


Centrifugal Pumps:

These pumps use a rotating impeller to increase the velocity of the fluid, which is then converted to pressure energy. They are suitable for transferring liquids with low viscosity and can handle a wide range of flow rates and pressures.


Positive Displacement Pumps:

These pumps use a mechanical action to move the fluid through the pump. They are suitable for handling fluids with high viscosity or high pressure, and are often used in applications where precise flow control is required.


Diaphragm Pumps:

These pumps use a flexible diaphragm to move the fluid through the pump. They are suitable for handling corrosive or abrasive fluids, and are often used in applications where contamination of the fluid must be minimized.


Gear Pumps:

These pumps use meshing gears to move the fluid through the pump. They are suitable for handling high viscosity fluids, and are often used in applications where precise flow control is required.


Screw Pumps:

These pumps use a rotating screw to move the fluid through the pump. They are suitable for handling high viscosity fluids, and are often used in applications where precise flow control is required.
