Product Description
Summarize:
Models 2BV and SK are single stage liquid ring vacuum pumps.
Model 2SK is double stages liquid ring vacuum pump.
The liquid-ring vacuum pump compresses gas by rotating a vaned impeller within a cylindrical casing. Liquid (usually water) is fed into the pump, and by centrifugal acceleration, forms a moving cylindrical ring against the inside of the casing. This liquid ring creates a series of seals in the space between the impeller vanes, which form compression chambers. The eccentricity between the impeller’s axis of rotation and the casing geometric axis results in a cyclic variation of the volume enclosed by the vanes and the ring.
Gas, often air, is drawn into the pump through an inlet port in the end of the casing. The gas is trapped in the compression chambers formed by the impeller vanes and the liquid ring. The reduction in volume caused by the impeller rotation compresses the gas, which reports to the discharge port in the end of the casing.
Compressed gas on discharge of pump contains certain amount of working liquid which is usually removed in vapor-liquid separator.

Disadvantages of using a vacuum pump
A vacuum pump is a device that pulls gas molecules out of a volume and leaves a partial vacuum. Its main function is to create a relative vacuum within a given volume. There are several types of vacuum pumps. Some of them are better suited for specific purposes than others. However, there are some disadvantages to using a vacuum pump.
Application of vacuum pump
Vacuum pumps are invaluable tools in many industrial and scientific processes. They are often used to move gas and other harmful substances and to clear clogged drains. They are also used to support mechanical equipment. For example, they can be mounted on the engine of a motor vehicle or the power hydraulic component of an aircraft. No matter how they are used, they should fit the application.
The principle of a vacuum pump is to draw gas from a sealed chamber to create a partial vacuum. Over the years, vacuum pump technology has evolved from its original beginnings to its current form. Today, there are many types of vacuum pumps, including rotary vane pumps, momentum transfer pumps, and regeneration pumps.
The semiconductor industry is a major user of vacuum pumps. Among other applications, these pumps are commonly used for mounting circuit boards, securing components, blowing and jetting, and pumping. The use of renewable resources has paved the way for widespread semiconductor production, where vacuum pumps are crucial. This manufacturing shift is expected to boost vacuum pump sales across Europe. 
The most common types of vacuum pumps are positive displacement and rotary vane pumps. Positive displacement pumps are most effective for rough vacuum applications and are usually paired with momentum transfer pumps. These pumps are used in pharmaceutical, food and medical processes. They are also used in diesel engines, hydraulic brakes and sewage systems.
Positive displacement pumps are used to create low vacuum conditions and create a partial vacuum. These pumps create lower air pressure by enlarging the chamber and allowing gas to flow into the chamber. The air in the cavity is then vented to the atmosphere. Alternatively, momentum transfer pumps, also known as molecular pumps, use high-speed rotating blades to create dense fluids. 
Their drawbacks
Vacuum pumps are useful in industrial applications. However, they are not perfect and have some drawbacks. One of them is that their output is limited by the vacuum hose. Vacuum hoses are the bottleneck for vacuum pump performance and evacuation rates. The hose must be kept free of water and organic matter to ensure the highest possible vacuum.
Dry vacuum pumps do not have these problems. They may be more cost-effective but will increase maintenance costs. Water consumption is another disadvantage. When pond water is used, the pump puts additional pressure on the treatment facility. Additionally, contaminants from the gas can become trapped in the water, shortening the life of the pump.
Another disadvantage of vacuum pumps is their limited operating time at low vacuum. Therefore, they are only suitable for extremely high vacuum levels. Diaphragm pumps are another option for industrial applications. They have a sealed fluid chamber that allows a moderate vacuum. They also feature short strokes and a low compression ratio, making them quieter than their reciprocating counterparts.
Vacuum pumps are used in many industrial and scientific processes. They can be used to transport hazardous materials or clear clogged drains. They are also used in rear doors and dump tanks. Certain types of vacuum pumps can cause fluid blockages, which can be harmful. The vacuum pump should also be well suited to the fluid in it to avoid contamination.
Another disadvantage is the lack of proper vacuum system testing equipment. Mechanics often underestimate the importance of a properly functioning vacuum system. Most stores lack the equipment needed for proper troubleshooting. Typically, mechanics rely on the cockpit vacuum gauge to determine if the pump is working properly.
Some vacuum pumps are capable of providing constant vacuum. These pumps are also capable of eliminating odors and spills. However, these advantages are outweighed by some disadvantages of vacuum pumps.
