A Guide to the Different Types of Industrial Pumps

Industrial pumps play a role in a range of industries, facilitating the movement of diverse fluids for various purposes. They handle tasks like transferring water, managing chemicals, and dealing with thick slurries, ensuring smooth operations in different processes. Due to the nature of these tasks, there is no universal pump solution that fits all needs perfectly. Therefore, selecting the pump type tailored to your requirements is essential for optimal performance and cost efficiency.

This blog will take an in-depth look at the classifications of pumps—positive displacement and dynamic pumps—discussing their functions, benefits, and ideal usage scenarios. We'll also examine IDEX Fluid Management Technologies (IDEX FMT), a supplier renowned for producing top-notch pumps recognised for their longevity and cutting-edge features.

Exploring the Two Key Categories of Industrial Pumps

1. Positive displacement pumps

Positive displacement pumps work by capturing a fixed amount of fluid within a chamber before expelling it through an outlet. This mechanism ensures a controlled flow rate irrespective of the discharge pressure, making them suitable for applications demanding control.

Here are a few common positive displacement pump varieties and their benefits:

·       Reciprocating pumps (such as piston and diaphragm pumps): These pumps are great for high-pressure tasks and handling fluids because of their positive displacement mechanism.

·       Gear Pumps: These pumps are straightforward and dependable, excelling at moving liquids smoothly with minimal pulsation.

·       Lobe Pumps: Similar to gear pumps but quieter than them; lobe pumps work efficiently with liquids and materials to shear.

·       Screw Pumps: With the ability to handle solids and high viscosities, screw pumps have the advantage of self-priming.

2. Dynamic Pumps

Dynamic pumps operate differently from displacement ones by using centrifugal force to move fluids. By rotating an impeller, kinetic energy is imparted to the fluid, converting it into pressure upon exiting the pump. While dynamic pumps offer flow rates, they may not consistently maintain flow when pressure varies.

Advantages of Various Pumps

·       Centrifugal Pumps: Among the industrial pump types, centrifugals provide high flow rates suitable for clean or slightly viscous liquid applications. They often prove to be more cost-effective than displacement pumps for transferring large volumes.

·       Submersible Pumps: These pumps are designed to work underwater, making them perfect for emptying tanks, sumps, and areas with elevation.

·       Vertical Turbine Pumps: Ideal for wells and situations that require moving volumes of liquid from significant depths Vertical turbines come in a compact design.

Factors to Keep in Mind for Choosing the Right Pump

Deciding on the pump depends on factors specific to your needs. Here are some important things to consider:

·       Fluid Characteristics: Think about the thickness, abrasiveness, and whether there are solids in the liquid being transferred.

·       Flow Rate and Pressure Needs: How much needs to be pumped, and at what pressure?

·       Head (vertical distance): The height that the liquid must be raised to.

·       Efficiency: Assess how much power the pump consumes compared to its output.

·       Maintenance Requirements: Take into account accessibility, how often maintenance is needed, and the availability of replacement parts.

Specialised Types of Industrial Pumps and Their Uses

While displacement and dynamic pumps serve as the primary categories, the world of industrial pumps encompasses a wide array of specialised types tailored to address unique challenges across different sectors. Here are some examples:

·       Metering Pumps: These positive displacement pumps excel at delivering low volume amounts of fluids for chemical processing, dosing applications, and accurate dispensing in food and beverage manufacturing.

·       Vacuum Pumps: Designed to remove gases from sealed chambers, vacuum pumps play a role in processes such as degassing liquids, freeze drying, and creating vacuum environments for vapour deposition.

·       Air-operated double-diaphragm (AODD) pumps: These versatile pumps use compressed air to transport fluids efficiently, offering self-priming capabilities and the ability to handle solids, abrasives, and viscous liquids. They find applications in mining operations, wastewater treatment plants, and chemical processing facilities.

·       Peristaltic Pumps: These unique pumps use a rotating tube to push fluid through a chamber, making them perfect for tasks that require the handling of sterile or delicate fluids. They are commonly used in industries such as pharmaceuticals, food and beverage, and biotechnology.

·       Multistage Pumps: When high pressure is required, multistage pumps come into play by incorporating impellers in a single housing. Each impeller increases the pressure of the fluid, making these pumps ideal for applications like oil and gas transport, boiler feed systems, and high-pressure cleaning tasks.

Looking Beyond the Basics: Key Considerations for Pump Selection

After exploring types of pumps, let's now dive deeper into the factors that influence your pump choice:

·       Material Compatibility: It's crucial to ensure that the materials used in the pump are compatible with the fluid being transferred. Factors like resistance to corrosion, tolerance to temperature variations, and durability against wear must be taken into account to guarantee the pump's longevity and safe operation.

·       Net Positive Suction Head (NPSH): This parameter indicates the minimum pressure needed at the pump inlet to prevent cavitation, which has an effect on the pump impeller. Understanding your application's NPSH requirements and selecting a pump with a NPSH rating is essential.

·       Sealing Options: The type of seal used in a pump plays a role in preventing leaks and maintaining operation. Various seal designs are tailored to levels of pressure, temperatures, and types of fluids.

·       Features for Control: Certain pumps come with options like speed drives or pressure control features that allow you to make adjustments to enhance performance and reduce energy consumption based on your requirements.

Ensuring Optimal Performance: Essential Tips for Pump Maintenance

Maintenance plays a role in ensuring the durability and efficient operation of your industrial pump. Here are some important practices to keep in mind:

·       Routine Inspections: Regularly check the pump for any signs of wear, leaks, or damage. Adhering to the maintenance schedule recommended by the manufacturer is essential.

·       Proper Lubrication: Ensuring lubrication of bearings and seals is vital to minimising friction and extending the lifespan of the pump.

·       Performance Monitoring: Keep an eye on performance indicators such as flow rate, pressure levels, and vibrations to detect issues early on and address them promptly.

·       Following Guidelines: Always follow the manufacturer's instructions for both operating and maintaining the pump to ensure its effective operation.

By incorporating these practices, you can prolong the life expectancy of your pump while reducing downtime.
