What is the Best Type of Chemical Transfer Pump?

A chemical transfer pump is essential to operations across numerous industries. These pumps make transfers safer and more efficient. In some cases, the task would be impossible without the right chemical transfer pump.

Of course, some pumps are better for the job than others. Which is best? The best chemical transfer pump for each application is largely determined by the type of fluid involved, the distance the fluid needs to travel, and the flow rate required.

Based on these variables, pump owners may choose a centrifugal pump or a positive displacement pump for their systems. For example, if the fluid is highly viscous, positive displacement pumps may be the preferred choice.

What are the available options? Following are the most common types of chemical transfer pump:

  • Centrifugal: Sealed or Sealless
  • Positive Displacement: AODD, Rotary lobe, Gear, Vane, or Peristaltic

While each of these types has merit, centrifugal pumps are frequently selected due to their high efficiency and simple design. Because they are often the top choice, let’s take a closer look at the main types of centrifugal chemical transfer pumps and how to choose the best one for your application.

Sealed vs. Sealless Centrifugal Chemical Transfer Pump

A centrifugal chemical transfer pump is designed as either sealed or sealless.

A chemical transfer pump with a mechanical seal can offer the perfect solution for applications that require the transfer of liquids that contain solids. A second advantage of these pumps is the cost. Compared to sealless pumps, these styles are typically available at a lower price point.

A sealless centrifugal transfer pump, on the other hand, offers unique advantages. By eliminating the seal (which eventually fails), the sealless design prevents leaks and emissions. For some applications, this is critical, because they involve toxic chemicals, corrosive liquids, or flammable fluids that would pose extreme hazards if a leak occurred.

Sealless pumps are also extremely reliable and require very little maintenance. They often can operate for a decade or more without requiring any repairs. This advantage offsets the higher initial cost of this style of pump. The overall savings during the lifetime of the pump typically exceed the additional cost that owners incur when purchasing the pump.

Ultimately, the final decision regarding which chemical transfer pump to use for your application should be based on the unique characteristics of your operations. However, in any application, certain qualities are key. As you choose a chemical transfer pump, always consider the following three factors.

Factors to Consider

Reliability

How long can you expect the pump to last? How often will it require maintenance? Will your operations suffer from frequent down time?

If you can’t rely on a chemical transfer pump to deliver quality performance, it’s not the right pump for your application. When you select a pump, you’re making an investment in your operations, with the accompanying expectation of a good return on that investment. You need to be able to count on the pump to keep your application running smoothly and safely. To choose the best chemical transfer pump, look for one with proven reliability.

Suitability

Not every chemical transfer pump is suitable for each application. Basic application parameters to consider include:

  • Fluid concentration
  • Specific gravity
  • Viscosity
  • Solids data
  • Temperature
  • Flammability

To determine which chemical transfer pump is most suitable for your application, consider using tools such as an online pump guide, pump selector, and chemical compatibility guide. These resources can quickly point you in the right direction to find the best chemical transfer pump.

Manufacturer

If you’re going to entrust the safety and efficiency of your operations to a chemical transfer pump, it should be branded with a name you can trust. Look for a manufacturer that has a track record of success in the industry. Choose one that stands behind their products with excellent service and extended warranties and quality reputation.
