Explore the Different Types of Industrial Pumps and Use in the Oil & Gas Sector

An industrial pump is a mechanical device designed to move fluids—including liquids and gases—through a piping system, facilitating the transfer, circulation, or processing of materials in various industrial applications. By converting mechanical energy from a motor or manual operation into fluid motion, industrial pumps enable the control of flow rate and pressure, meeting specific operational requirements.



An industrial pump is a sophisticated mechanical device engineered to transfer or move fluids (liquids, gases, or slurries) from one location to another within industrial settings. It operates by converting mechanical energy from an external source—such as an electric motor, diesel engine, or manual operation—into hydraulic energy that propels the fluid through the system. This process involves the creation of flow and pressure, enabling the controlled movement of materials in various phases of industrial operations.

Industrial pumps are fundamental components across a wide spectrum of industries including, but not limited to, water treatment, oil and gas production, chemical manufacturing, food and beverage processing, pharmaceuticals, construction, and mining. Their applications range from pumping water from wells, processing, and moving chemicals, providing hydraulic fluid to machinery, to circulating coolants in power plants.


Industrial pumps, integral to various sectors for moving fluids through systems, comprise multiple components, each serving a specific function to ensure efficient and reliable operation. Here’s a detailed look at the key parts and components of an industrial pump:

1. Casing

The casing is the exterior shell of the pump that houses the internal components. It serves several functions:

  • Containment: It contains the fluid being pumped, directing it from the inlet to the discharge point.
  • Pressure Containment: The casing is designed to withstand the operating pressures of the pump.
  • Support: It supports the internal components and connects the pump to the piping system. Casings can be volute or diffuser type, depending on the pump design.

2. Impeller

The impeller is the heart of a centrifugal pump. It’s a rotating component with vanes, designed to impart energy to the fluid:

  • Energy Transfer: As the impeller rotates, it transfers kinetic energy to the fluid, increasing the fluid’s velocity and pressure.
  • Materials: Impellers can be made from various materials, including metals, plastics, or ceramics, based on the fluid characteristics and application requirements.

3. Shaft

The shaft transmits mechanical power from the motor or drive mechanism to the impeller, causing it to rotate. It’s typically made from robust materials to resist torsional and bending stresses.

4. Bearings

Bearings support the shaft, allowing it to rotate smoothly and with minimal friction. They absorb radial and axial loads imposed by the operation of the pump. Bearings require lubrication to minimize wear and can be either grease-lubricated or oil-lubricated.

5. Seal

Seals prevent the leakage of fluid from the pump casing. There are two main types:

  • Packing Seal: A traditional sealing method using braided material that is compressed around the shaft to create a seal.
  • Mechanical Seal: A more modern solution consisting of two flat surfaces that slide against each other, one fixed to the shaft and the other to the casing, to form a seal. Mechanical seals can handle higher pressures and are more effective at preventing leaks.

6. Suction and Discharge Nozzles

These are the points at which the fluid enters and exits the pump:

  • Suction Nozzle: Located at the pump’s inlet, it’s designed to facilitate the smooth entry of fluid into the pump.
  • Discharge Nozzle: Situated at the pump’s outlet, it directs the pumped fluid into the discharge piping.

7. Coupling

The coupling connects the pump’s shaft to the motor’s shaft, transmitting rotational power to the pump. It compensates for minor misalignments and can absorb some shock loads.

8. Baseplate

The baseplate provides a stable foundation for the pump and the motor or drive unit. It ensures the proper alignment of the pump with the motor and facilitates easier installation and maintenance.

9. Motor or Drive Mechanism

Though not technically part of the pump, the motor or drive mechanism is crucial for operation. It provides the mechanical energy required for the pump to function, whether it’s an electric motor, a diesel engine, or a pneumatic or hydraulic drive.

Each component of an industrial pump is critical for its performance, efficiency, and reliability. Understanding these components and their functions is essential for the selection, operation, and maintenance of the pump within industrial applications.


Understanding the key technical features of pumps, such as pump curves and cavitation, is essential for selecting, operating, and maintaining pumps efficiently in various industrial applications. These features provide critical insights into a pump’s performance and operational limits, helping to ensure reliable and effective fluid handling.

Pump Curves

Pump curves are graphical representations that illustrate a pump’s performance characteristics. The main types of curves include:

  • Head vs. Flow Rate Curve: This shows the relationship between the discharge head (pressure) a pump can generate and the flow rate. As the flow rate increases, the head typically decreases. This curve is fundamental for pump selection, ensuring the pump meets the specific head and flow requirements of the application.

  • Efficiency Curve: Illustrates the pump’s efficiency at different flow rates. Efficiency peaks at a specific flow rate known as the Best Efficiency Point (BEP). Operating near the BEP is crucial for minimizing energy consumption and wear.

  • Power Curve: Displays the power consumption of the pump across different flow rates. Power requirements increase with both flow rate and head. This curve helps in sizing the motor or drive system.

  • Net Positive Suction Head (NPSH) Curve: Shows the required NPSH at different flow rates to avoid cavitation. NPSHr (required) must be lower than NPSHa (available) to prevent cavitation and ensure smooth operation.


Cavitation is a phenomenon that occurs when the pressure in a pump falls below the liquid’s vapor pressure, leading to the formation of vapor bubbles in the fluid. These bubbles collapse or implode when they move to higher-pressure regions within the pump, causing shock waves that can erode and damage the impeller and other pump components. Key aspects include:

  • Causes: Cavitation is typically caused by high pump speeds, high temperatures, excessive suction lift, or insufficient NPSHa. It can also result from obstructions or sharp bends in the suction piping.

  • Effects: Besides physical damage to the pump, cavitation can lead to decreased flow rates, reduced head, increased power consumption, vibration, and noisy operation.

  • Prevention: To prevent cavitation, ensure adequate NPSHa, minimize suction lift, reduce fluid temperature if possible, and select a pump designed to operate within the specific system conditions. Additionally, optimizing the piping design to reduce flow restrictions and using variable speed drives to adjust pump operation can help avoid cavitation.

Understanding pump curves and recognizing the risks and implications of cavitation are crucial for the proper selection, operation, and maintenance of pumps in industrial settings. By carefully considering these factors, engineers can optimize pump performance, extend equipment lifespan, and maintain efficient and reliable fluid handling systems.

Centrifugal pumps are a cornerstone in the oil and gas industry, offering a reliable and efficient solution for fluid movement across a spectrum of applications. Their design and operational flexibility make them a preferred choice for meeting the rigorous demands of oil and gas production, transportation, and refining processes.

2. Positive Displacement Pumps

Unlike centrifugal pumps, positive displacement (PD) pumps move a fixed amount of fluid for each revolution or cycle of the pump, creating a steady flow rate regardless of the system pressure. PD pumps are categorized into two main types:

Rotary Pumps: These pumps use rotating elements to transfer the fluid. Types include:

  • Gear Pumps: Use two interlocking gears to pump the fluid. Ideal for high-viscosity fluids.
  • Screw Pumps: Employ one or more screws to move fluids along the screw axis.
  • Lobe Pumps: Similar to gear pumps but use lobes instead of gears, suitable for handling sensitive fluids without damaging them.

Reciprocating Pumps: These pumps use a reciprocating mechanism to move the fluid. Types include:

  • Piston Pumps: Utilize a piston moving within a cylinder to draw in and expel the fluid.
  • Diaphragm Pumps: Use a flexible diaphragm instead of a piston. The diaphragm’s movement varies the volume of the pump chamber to draw in and expel the fluid. They are particularly useful for pumping hazardous or corrosive fluids since the fluid is completely contained within the diaphragm chamber.

3. Submersible Pumps

Submersible pumps are designed to be submerged in the fluid they are pumping. They are typically used for pumping water from wells, removing sewage, and in drainage applications. Their design prevents pump cavitation, an issue associated with a high elevation difference between the pump and the fluid surface.

4. Diaphragm Pumps

Also known as Air-Operated Double Diaphragm (AODD) pumps, these are a type of positive displacement pump that uses compressed air as a power source. The air alternately flexes the diaphragm, causing suction and discharge of the fluid. Diaphragm pumps are excellent for transferring chemicals, viscous liquids, and fluids containing solids or abrasives.

5. Metering Pumps

Metering pumps, or dosing pumps, are precision positive displacement pumps designed to deliver a very accurate flow rate of a chemical or substance into a fluid stream. They are essential in applications requiring precise dosages of chemicals, such as water treatment, chemical processing, and food manufacturing.

6. Peristaltic Pumps

Peristaltic pumps, or hose pumps, operate by compressing and relaxing a flexible tube or hose with rollers or shoes. The fluid is contained within the tube, making these pumps ideal for handling sterile, abrasive, or aggressive fluids without any risk of contamination or damage to the pump.

7. Vacuum Pumps

Vacuum pumps remove gas molecules from a sealed volume to leave behind a partial vacuum. They are widely used in industrial and scientific processes, including semiconductor processing, vacuum coating, and freeze-drying.

Each type of industrial pump has unique characteristics that make it suitable for specific applications. Factors influencing pump selection include the nature of the fluid to be pumped, the required flow rate and pressure, the operating environment, and specific application requirements.
