5 Things You Probably Didn't Know About Centrifugal Chemical Pumps

If your operations require the transfer of fluids, you’re probably familiar with centrifugal pumps. If your specific applications involve the transfer of harsh substances, you might also be familiar with centrifugal chemical pumps, which are designed to withstand fluids that other pumps can’t handle.


However...


Even those who work, manage, or own operations that utilize centrifugal chemical pumps are often not fully aware of the capabilities of these devices. You might be surprised to discover the following facts about centrifugal chemical pumps.

1. They Conserve Energy

Each year, manufacturing facilities use an average of 95.1 kilowatt-hours of electricity and 536,500 Btu of natural gas per square foot. As facility owners seek sustainable solutions, any components that can create energy-saving operations are a win. Centrifugal chemical pumps fall into this category. Compared to other pumping technologies, centrifugal chemical pumps rank high in energy efficiency.


This energy conservation offers two key benefits. First, the efficiency reduces operating costs. Second, the pumps are less demanding of the energy systems involved. This is particularly important when facility managers must run multiple pumps and other equipment simultaneously. The energy-efficient centrifugal chemical pumps reduce the strain that large operations can place on energy supplies.

2. They’re Smooth Operators

Centrifugal chemical pumps offer smooth, accurate flow. This reduces the risk of system failure or production compromises that can be caused by pulsation. With these pumps in place, it is also likely that flow conditioners and pulsation dampeners will not be necessary, which reduces the cost and complexity of the systems involved.


This smooth operation is particularly crucial when transferring chemicals that require high safety measures and delicate handling. It is also key when systems must be able to deliver precision fluid transfers. The smooth flow provided by centrifugal chemical pumps provides accurate, reliable transfer, without sacrificing speed and volume.

3. They Can Run Dry

For many pumps, a run-dry situation is a destructive situation. In just a few minutes, the pump can be damaged and will require significant repairs or replacement. This isn’t the case with specialized centrifugal chemical pumps. Equipped with a carbon bushing, Finish Thompson centrifugal chemical pumps can run dry for extended periods.

The carbon bushing material offers a low coefficient of friction while rare earth magnets reduce the rotating mass. This innovative design prevents damage to the pump in a run-dry situation. If a system malfunction or human error occur that cause a run-dry scenario, these pumps have the robust construction to survive.

4. They’re Built to Last

Centrifugal chemical pumps often feature corrosion-resistant materials of construction. Their durable construction makes them impervious to even the harshest chemicals. Applications that would quickly cause wear and tear to other designs are not an issue for these pumps. They can operate under extreme conditions while delivering long-lasting performance. With a low-maintenance design, centrifugal chemical pumps also require less attention and repair than other pump styles.


This durability provides two benefits. First, operators can process corrosive chemicals without concern for pump damage. Second, the pumps offer long lifespans with little maintenance, which reduces cost and delivers great ROI.

5. They’re Very Versatile

Centrifugal chemical pumps are available in various configurations to suit a full range of applications. Due to their versatility, they are the most commonly used pump style for the transfer of low-viscosity fluids in lower head and high flow applications. They are also a popular choice for unique applications requiring durable design.


Self-priming pumps are designed for pumping from above the fluid level or can be mounted at ground level to pull fluid from the top of double-wall tanks, railcars and tanker trucks, while flooded suction pumps can be mounted on a tank’s exterior, and vertical models offer a smaller footprint for applications with limited space.


Various styles of centrifugal chemical pumps are ideal for applications across multiple industries, including:

Mag Drive Pump Applications

The features noted above make mag drive pumps ideal for myriad industrial applications. Pump owners in a wide variety of settings can rely on a mag drive pump to provide a robust solution for their operations. These applications include:

  • Chemical manufacturing/distributing: Transfer and circulate chemicals; Load and unload trucks and railcars
  • Water/wastewater treatment: Transfer chemicals; Disinfect; Empty tanks; Unload chemicals from bulk storage
  • DEF: Dispensing; Portable transfers; Container-to-container transfers; Blending
  • Electroplating and anodizing: Provide flow through eductors and filters; Transfer waste water; Transfer chemicals
  • Food and beverage: Transfer additives; Pump products to containers; Pump water for cleaning processes
  • Aquarium/aquatic life
  • Automotive
  • Bio-filtration and odor control
  • Bio-fuels
  • Mining
  • Paper and pulp industry
  • Pharmaceutical and medical
  • Power plants
  • Printed circuit boards and electronics
