Fluid Handling Systems

What are Fluid Handling Systems?

Fluid handling systems (pumps) are designed to transport, control, and manage the flow of fluids (liquids, gases, or slurries) through various pipelines, equipment, and processes. These systems are integral to industries like oil & gas, chemical processing, water treatment, food and beverage, and more. Fluid handling equipment, including a variety of pumps, ensures that fluids are moved efficiently, safely, and at optimal pressure and flow rates. Pumps, valves, and other components work together to deliver reliable, high-performance solutions to meet the specific needs of each application.

Types of Fluid Handling Equipment

Fluid handling systems rely on a variety of pump types, each designed for specific applications based on the fluid being handled, the required pressure, and the system’s overall design. Below are some of the most common types of pumps used in fluid handling systems.

Centrifugal Pumps

Centrifugal pumps are widely used in fluid handling systems for low-viscosity fluids. They work by using rotational energy from an impeller to increase the pressure of the fluid, pushing it through the pump system. These pumps are ideal for applications such as water supply, HVAC, chemical processing, and industrial fluid circulation.

  • Applications: Water treatment, HVAC systems, chemical processing, irrigation and dredging, and general fluid transport.
  • Advantages: Efficient, cost-effective, and suitable for continuous flow applications.

Types of Centrifugal Pumps

Charge Pumps

A charge pump is a type of centrifugal pump used to “charge” or supply fluid to another pump, ensuring it operates at optimal conditions. Charge pumps are commonly used in high-pressure systems, such as multi-stage pump setups or boiler feedwater systems. By maintaining the required inlet pressure for the main pump, they prevent cavitation and ensure a steady, controlled flow of fluid, optimizing overall system performance.

  • Applications: High-pressure systems, multi-stage pump setups, boiler feedwater systems.
  • Advantages: Prevents cavitation, ensures steady flow and optimal performance.

Positive Displacement Pumps

Positive displacement pumps work by moving a fixed volume of fluid with each cycle, making them ideal for high-viscosity fluids and applications requiring precise flow control. Unlike centrifugal pumps, which move fluids continuously, positive displacement pumps can handle fluids under higher pressure or in systems requiring tight flow regulation.

  • Applications: Chemical processing, oil & gas, food and beverage, and pharmaceuticals.
  • Advantages: Precise flow control, ideal for high-viscosity fluids.

Types of Positive Displacement Pumps

Diaphragm Pumps

Diaphragm pumps are versatile, self-priming positive displacement pumps capable of handling viscous, abrasive, or chemically aggressive fluids. These pumps are widely used in wastewater treatment, chemical applications, and industries where contamination must be avoided.

  • Applications: Chemical processing, wastewater treatment, food processing.
  • Advantages: Handle corrosive fluids, self-priming, reliable in harsh conditions.
Gear Pumps

Gear pumps use rotating gears to move fluid and are commonly used in high-viscosity fluid applications, such as oils and lubricants. The gears mesh together to displace the fluid, providing a consistent flow rate under pressure.

  • Applications: Oil & gas, chemical, lubrication systems.
  • Advantages: High efficiency, consistent flow, and ideal for high-viscosity fluids.
Piston/Plunger Pumps

Piston or plunger pumps are used in high-pressure applications where high-volume, high-pressure fluid movement is needed, such as in oilfield services, well drilling, and high-pressure cleaning. These pumps can handle very high pressures and provide consistent flow over time.

  • Applications: Oil & gas drilling, well servicing, high-pressure cleaning.
  • Advantages: High-pressure handling, long service life.
Mud Pumps

Mud pumps are a specialized type of piston pump designed for high-pressure applications, particularly in oil and gas drilling. They circulate drilling mud or slurry through the wellbore to cool the drill bit, stabilize the borehole, and carry out cuttings. Mud pumps are critical to the drilling process and are built to withstand high-pressure conditions.

  • Applications: Oil and gas drilling, mining, construction.
  • Advantages: High-pressure operation, critical for drilling and slurry handling.
Frac Pumps

Frac pumps are a specialized type of positive displacement pump designed for the demanding conditions of hydraulic fracturing (fracking) in the oil and gas industry. These high-pressure pumps are essential for injecting a mixture of water, sand, and chemicals into underground rock formations to create fractures, allowing oil and gas to flow more freely.

Applications 

  • Hydraulic Fracturing: Frac pumps are primarily used in hydraulic fracturing, or fracking, to stimulate oil and gas wells.

  • Well Stimulation: Used to improve the productivity of a well by creating fractures in the reservoir, allowing for increased fluid flow.

  • High-Pressure Applications: Frac pumps are designed to operate under extreme pressure, making them ideal for deep-well stimulation projects.

Advantages

  • High Pressure: Capable of delivering fluids at pressures up to 15,000 psi, making them ideal for deep well operations.
  • Durability: Built to withstand the intense pressures and abrasive nature of the frac fluids.
  • Efficiency: Ensures fast and precise fluid delivery, which is critical for successful fracturing operations.

Peristaltic Pumps

Peristaltic pumps use rollers to compress a tube, moving fluid through it. These pumps are ideal for sterile or sensitive liquids that require minimal exposure to external elements. Peristaltic pumps are commonly used in medical, food, and chemical industries, where precision and contamination-free operations are critical.

  • Applications: Food and beverage, pharmaceutical, chemical dosing, medical.
  • Advantages: Sterile handling, no contamination risk, precise fluid control.

Submersible Pumps

Submersible pumps operate fully submerged in the fluid they are pumping, making them ideal for applications such as sewage, drainage, and slurry handling. They are built to be durable, handling fluids with solids or debris, and often used in wastewater systems and flood control.

  • Applications: Sewage systems, stormwater drainage, mining operations.
  • Advantages: Self-priming, high durability, ideal for slurry and dirty water applications.

Vacuum Pumps

Vacuum pumps remove air and gases to create a vacuum, enabling fluid transfer in systems where suction is required. These pumps are commonly used in laboratories, food processing, and industrial applications to handle gases or create low-pressure environments for fluid transfer.

  • Applications: Laboratories, food packaging, industrial systems, and vacuum applications.
  • Advantages: Creates low-pressure environments, critical for specific fluid transfer processes.

Magnetic Drive Pumps

Magnetic drive pumps utilize a magnetic field to transfer power from the motor to the pump, eliminating the need for seals. This makes them ideal for handling hazardous, corrosive, or volatile fluids in chemical processing and similar industries. The absence of seals reduces the risk of leaks and contamination.

  • Applications: Chemical processing, pharmaceuticals, hazardous fluid transport.
  • Advantages: Leak-free operation, ideal for handling hazardous fluids.

Multi-stage Pumps

Multistage pumps have multiple impellers that allow for high-pressure output, making them suitable for applications requiring consistent, high-pressure fluid movement. These pumps are commonly used in systems like boiler feed, water injection, and high-rise buildings, where maintaining a high pressure is critical.

  • Applications: Boiler feed systems, water injection systems, high-rise buildings.
  • Advantages: High-pressure capabilities, reliable in demanding applications.
