What are the 6 Key Limitations of Rotary Pumps?

Rotary pumps are widely used in various applications, but they do come with certain limitations that users should be aware of.

Discover the 6 Key Limitations of Rotary Pumps

What are the 6 Key Limitations of Rotary Pumps?

1. Nonlubricating Fluids

Rotary pumps require adequate lubrication for their internal parts to function properly. Fluids with poor lubricating qualities, such as LPG, gasoline, and water, are not suitable for continuous service in rotary pumps.

2. Regular Maintenance

Rotary vane pumps, a type of rotary pump, require regular maintenance. This maintenance can be costly and time-consuming, involving tasks like oil top-ups and filter replacements.

3. Oil Contamination

Oil-sealed rotary vane pumps release oil mist into the immediate atmosphere, even with oil filter hardware. This can lead to contamination of process gases and the surrounding environment.

4. Safety Risks

In some cases, flooding of the pump can cause solvent to squirt out of the back, creating fire safety hazards or health risks when using corrosive or carcinogenic solvents.

5. Solvent Loss

If solvent does not have enough time to condense into the collection flask, it cannot be recovered. This can result in a decrease in solvent recovery rate.

6. Inefficient Process

Using a rotary pump that is not powerful enough for the application can lead to a slow and inefficient process.

It is crucial to consider these limitations when selecting a vacuum pump system for specific laboratory needs. Dry pump systems have emerged as a favorable alternative to oil-sealed rotary vane pumps, offering benefits such as no oil replacements, longer service intervals, low noise levels, and no contamination of process gases or environment.
