Dry Screw Vacuum Pump and Its Advantages

 Dry screw vacuum pumps are the latest edition to the industry. These work on the principle of no lubricants i.e. no water, no oil, which makes the dry screw pumps ecologically sound. Dry screw pumps consist of two screws rotating in opposite directions and the gas moves in the screw's axis. They are designed in different configurations to meet different needs. They can be often used in combination with a variety of pumps to work for any specific requirement.



Principle of operation

The dry screw vacuum pumps are worked under a pump casing which consists of two screw rotors with no friction between them, supported by bearings. It sucks the air in and pumps the medium between the cylinder and screw chambers and then transfers it to the gas exhaust. These pumps are very stable and produce less noise and required no lubricating oil for application. These pumps have a wide range of applications in different industries like steel plants, agrochemical industries, and many more.

Advantages of dry screw vacuum pumps

Following are some of the advantages for dry screw vacuum pump-

It has a very high pumping capacity.
Friction-free operation in different chambers.
It does not require the consumption of fuel, and results in zero leakage.
The operation and maintenance cost is low.
Highly efficient for various operations.
The pumps have anti-corrosion coating, which makes them highly durable
Environment-friendly because of no water, no oil principle.
No contamination of medium as it is directly discharged from the pump body.
It has dust resistance properties.

Application

Dry screw pumps have various applications in industrial vacuum systems. It is used for the distillation of chemicals, biodiesel, oil, polymer industries, oil refining industries. It has wide usage even in the food industry for packaging, drying, and processing, these pumps are used because of their no contamination of medium quality. It has application in steel plants due to its dust resistance property and high durability.

Dry screw pumps are mainly used with equipment like reactor distillation, multi-phase transportation of liquid, gas, or solid, oil-water separating devices, wastewater treatment system, column distillation, fractional distillation, etc.

These are some of the advantages and applications of dry screw vacuum pumps, which is using widely in the pumping industry as a latest and advanced technology to fulfill the specific needs.
