Today, industries are focused on boosting productivity while reducing emissions. Dry vacuum pumps are a great solution. They help companies improve efficiency, maintain high-quality output, and create a smaller environmental footprint.
A dry vacuum pump works without using oil or other fluids to create a vacuum. This means no risk of contaminating the process gas or producing waste. These pumps are also easier and cheaper to maintain compared to traditional wet vacuum pumps. Plus, they can recover leftover solvent vapors at the discharge stage.
Dry vacuum pumps handle tough and challenging gases in various industries. They are commonly used in processes like drying, solvent recovery, distillation, evaporation, crystallization, deodorization, and filtration.
There are two main types of dry vacuum pumps:
These pumps use two screw rotors that spin inside a cylinder. The gas gets trapped between the cylinder and the screws, then moves to the discharge area.
The screws are placed very close together to create a vacuum. However, sticky materials can cause the screws to rub and overheat, leading to damage. These pumps are also sensitive to temperature changes. If the rotors expand faster than the casing, they can seize.
The screws are coated with materials like PEEK or PFA. If condensation, particles, or overheating damage the coating, repairs are expensive and time-consuming. The entire pump must be sent to the vendor, causing downtime. These pumps work best for low-boiling materials with stable process conditions. For high-boiling or variable processes, maintenance costs can be high.
These pumps use two claw-shaped rotors that rotate in opposite directions. They suck in air or gas, compress it, and discharge it. An additional root stage helps achieve a better vacuum.
The vertical design prevents condensation and corrosion, unlike horizontal designs. These pumps handle sticky materials and temperature changes better, with less risk of internal damage.
The rotors don’t have coatings, making them more flexible and reducing maintenance costs. If one rotor is damaged, only that part needs replacement, not the entire pair. Repairs can be done on-site, avoiding long downtimes.
These pumps work well for both high and low-boiling materials. However, they are not suitable for fluids with a pH value below 2.
Dry vacuum pumps are cleaner and more reliable than traditional wet pumps. They don’t use oil or water, so there’s no risk of contamination. They provide a wide range of vacuum levels and need minimal maintenance. They are also safe for pumping flammable and corrosive vapors, making them ideal for pharmaceutical and chemical industries.
Vacuum pumps are essential in many industries like chemical, pharmaceutical, fertilizer, dairy, food processing, and steel plants. They are used for tasks such as drying, distillation, sterilization, degassing, and crystallization.
Picking the right vacuum pump is a big decision. Plant managers, engineers, and project teams carefully think about factors like the level of vacuum needed, maintenance, upfront costs, utility requirements, and the total cost over the pump’s lifetime.
There are four main types of vacuum pumps used in industries:

Mechanical Vapor Recompression (MVR) systems are a game-changer for industries. They recycle energy within the system, cutting down on energy use. A key part of MVR is creating and maintaining the right vacuum levels. This is where Roots Vacuum Pumps come in. These pumps, like twin lobe Roots Blowers, are vital for keeping the pressure difference needed for MVR to work efficiently. They can be customized for different uses, from treating wastewater to crystallization. Knowing how vacuum works in MVR systems is crucial for getting the best results. Let’s take a closer look at how vacuum works in MVR systems and the role of Roots Vacuum Pumps.
MVR systems need precise vacuum levels to function properly. The right vacuum level depends on factors like the type of process, the liquid being evaporated, and how well the system needs to perform.
When designing an MVR system, it’s important to consider these factors. This ensures the vacuum pump can achieve and maintain the right vacuum levels. Doing this improves energy efficiency and keeps the process stable.
Vacuum is key to making MVR systems more efficient. It creates a low-pressure environment, allowing liquids to evaporate at lower temperatures. This means the system uses less energy. Vacuum pumps also maintain a steady pressure difference, which helps the MVR system run smoothly and boosts its ability to recompress vapor.
Vacuum changes how quickly liquids evaporate and lowers their boiling points. When a vacuum pump creates low pressure, the boiling point of a liquid drops. This happens because liquid molecules need less energy to turn into vapor. As a result, evaporation happens faster and uses less energy. In MVR systems, this leads to quicker and more efficient evaporation.
MVR systems work better in low-pressure conditions. The vacuum pump reduces pressure in the evaporator, making the liquid boil at a lower temperature. This produces cooler, low-pressure vapor. Since the vapor is at a lower pressure, the MVR compressor needs less energy to compress it. This reduces the system’s overall energy use. The vacuum pump also ensures a steady flow of vapor from the evaporator to the compressor.
Roots vacuum pumps are a great match for MVR systems. They can handle large amounts of vapor and work well under different pressure conditions. Their sturdy design and positive displacement operation make them ideal for tough industrial tasks.
In MVR systems, Roots pumps work alongside the compressor. Together, they create and maintain the low-pressure environment needed for effective vapor recompression.
Roots vacuum pumps are essential for optimizing MVR systems. Here’s how they help:
Roots pumps make MVR systems more efficient and stable, saving energy and improving performance.
For MVR systems to work at their best, vapor compression and vacuum creation need to be perfectly synchronized. Roots vacuum pumps and compressors must work together to maintain the right pressure difference. The compressor increases the vapor’s pressure, while the Roots pump lowers the pressure on the evaporator side.
This teamwork ensures a steady flow of vapor. If the pressure isn’t balanced, the system can become less efficient or even shut down. This highlights the importance of proper control and coordination between the pump and compressor.
Roots vacuum pumps are crucial for improving the performance and efficiency of MVR systems. They provide the vacuum levels needed to boost efficiency and reduce energy use. Their design features, like internal lubrication and explosion-proof capabilities, make them reliable for various industries.
