Liquid Ring Vacuum pump
Product Description
ELMO-F vacuum pumps are designed by Siemens. The pumps are suitable for evacuating gases and wet vapoure down to inlet pressure of 33 mbar (97% vacuum).
All these vacuum pumps are supplied with built-in cavitation protection. For long-term operation below 80mbar abs. the cavitation protection should be connected for protecting the pump. An inlet pressure of 10 mbar abs. can be achieved by connecting a gas ejector(see accessories). The gas ejector can be mounted directly CZPT the vacuum pump.
The 2BV5 ELMO-F pumps are especially space-saving units in monoblock design(degree of protection IP55).
They are available in cast iron ( fitted with Stainless steel impeller and portplate) and in chrome-nickel steel (see table).

Basic knowledge of vacuum pump
A vacuum pump is used to create a relative vacuum within a sealed volume. These pumps take gas molecules out of the sealed volume and expel them, leaving a partial vacuum. They can be used in a variety of applications, including medicine and laboratory research. This article will cover the basics of vacuum pumps, including how they operate and the materials they use. You will also learn about typical applications and fees.
How it works
A vacuum pump is a pump that removes air from a specific space. These pumps are divided into three types according to their function. Positive displacement pumps are used in the low vacuum range and high vacuum pumps are used in the ultra-high vacuum range. The performance of a vacuum pump depends on the quality of the vacuum it produces.
A vacuum pump creates a partial vacuum above the surrounding atmospheric pressure. The speed of the pump is proportional to the pressure difference between the ambient atmosphere and the base pressure of the pump. Choose a base pressure for a specific process, not the lowest possible pressure in the system.
A scroll pump is also a type of vacuum pump. This type of pump consists of two scrolls, the inner scroll running around the gas volume. It then compresses the gas in a spiral fashion until it reaches the maximum pressure at its center. The inner and outer scrolls are separated by a polymer tip seal that provides an axial seal between them. Its pumping speed ranges from 5.0 to 46 m3/h.
Another type of vacuum pump is the screw pump, which uses two rotating screws in one chamber. The screw in the screw pump is a left-handed screw, and the other is a right-handed screw. The two screws do not touch each other when engaged, preventing contamination of the medium. They also feature high pumping speeds, low operating costs and low maintenance requirements.
The vacuum pump consists of several parts such as rotor and base. These components create an area of low pressure. Gas and water molecules rush into this low pressure area, where they are sucked into the pump. The pump also rotates, preventing fluid leakage to the low pressure side.
The main function of a vacuum pump is to remove gas particles from an enclosed space. It does this by changing gas molecules between high and low pressure states. A vacuum pump can also generate a partial vacuum. There are several types of vacuum pumps, each designed to perform a specific function, so it is important to choose the right type for your application.
Vacuum Pump Materials
There are two main materials used in vacuum pumps: metal and polyethylene. Metal is more durable, while polyethylene is cheaper and more flexible. However, these materials are not suitable for high pressure and may cause damage. Therefore, if you want to design a high-pressure pump, it is best to use metal materials.
Vacuum pumps are required in a variety of industrial environments and manufacturing processes. The most common vacuum pump is a positive displacement vacuum pump, which transports a gas load from the inlet to the outlet. The main disadvantage of this pump is that it can only generate a partial vacuum; higher vacuums must be achieved through other techniques.
Materials used in vacuum pumps vary from high to rough vacuum pumps. Low pressure ranges are typically below 1 x 10-3 mbar, but high vacuum pumps are used for extreme vacuum. They also differ in manufacturing tolerances, seals used, materials used and operating conditions.
The choice of vacuum pump material depends on the process. The vacuum range and ultimate pressure of the system must be carefully analyzed to find the right material for the job. Depending on the purpose of the pump, a variety of materials can be used, from ceramic to plastic substrates. When choosing a vacuum pump material, be sure to consider its durability and corrosion resistance.
Dry and wet vacuum pumps use oil to lubricate internal parts. This prevents wear of the pump due to corrosion. These types of pumps are also recommended for continuous use and are ideal for applications where the gas is acidic or corrosive. Therefore, they are widely used in the chemical and food industries. They are also used in rotary evaporation and volatile compound processing.
Positive displacement pumps are the most common type. They work by letting gas flow into a cavity and venting it into the atmosphere. Additionally, momentum transfer pumps, also known as molecular pumps, use high-velocity jets of high-density fluids to transport air and gases. These pumps are also used for medical purposes.
Typical application
Vacuum pumps are used to remove large amounts of air and water from the process. They are used in various industries to improve performance. For example, liquid ring vacuum pumps are used in packaging production to produce plastic sheets in the desired shape and size. Large-capacity suction pumps are used in the chemical industry to improve the surface properties of materials and speed up filtration.
There are two basic principles of vacuum pumps: entrapment and gas transfer. Positive displacement pumps are suitable for low to medium vacuums, while momentum transfer and retention pumps are suitable for high vacuums. Typically, high vacuum systems use two or more pumps working in series.
There are three main categories of vacuum pumps: primary, booster, and secondary. Their working pressure ranges from a few millimeters above atmospheric pressure. They also have several different technologies, including positive displacement, gas transfer, and gas capture. These pumps transport gas molecules through momentum exchange. Typically, they release gas molecules at roughly the same rate as they entered. When the process is complete, the gas molecules are slightly above atmospheric pressure. The discharge pressure is equal to the lowest pressure achieved, which is the compression ratio.
Vacuum pumps are widely used in all walks of life. They can be found in almost every industrial sector, including food processing. For example, they are used to make sausages and food products. In addition, they are used in landfill and digester compressors. They can also be used to build solar panels.
Oil lubricated vacuum pumps are currently the most energy-efficient vacuum pumps. These pumps are suitable for a variety of industrial applications including freeze drying and process engineering. These pumps use oil as a sealant and coolant, which makes them ideal for a variety of applications. These pumps are also very sensitive to vibration.
Another type of vacuum pump is a turbomolecular pump. These pumps have multiple stages and angled vanes. Unlike mechanical pumps, turbomolecular pumps sweep out larger areas at higher pumping speeds. In addition, they can generate ultra-high oil-free vacuums. Additionally, they have no moving parts, which makes them ideal for high vacuum pressures.
Vacuum Pump Cost
Annual maintenance costs for vacuum pumps range from $242 to $337. The energy consumption of the vacuum pump is also a consideration, as it consumes electricity throughout its operating cycle. For example, an electric motor for a 1 hp pump uses 0.55 kW/hr, which equates to 2,200 kWh of energy per year.
Energy cost is the largest part of the total cost of a vacuum pump. They are usually four to five times higher than the initial purchase price. Therefore, choosing a more energy efficient system can reduce the total cost of ownership and extend the payback period. For many clients, this can be millions of dollars.
A vacuum pump works by compressing gas as it enters a chamber. This pushes the gas molecules towards the exhaust. The exhaust gas is then vented to the atmosphere. A special spring-loaded vane seals the pump’s chamber, creating an airtight seal. Specially formulated oils are also used to lubricate, cool and seal rotors.
Vacuum pumps are not cheap, but they have many advantages over water suction. One of the main advantages of vacuum pumps is their flexibility and reliability. This is an industry-proven solution that has been around for years. However, the initial cost of a vacuum pump is higher than that of a water aspirator.
If the vacuum pump fails unexpectedly, replacement costs can be high. Proper maintenance can extend the life of your system and prevent unplanned downtime. However, no one can predict when a pump will fail, and if a pump does fail, the cost can far exceed the cost of buying a new pump. Therefore, investing in preventive maintenance is a wise investment.
There are many types of vacuum pumps, not all of which are suitable for the same type of application. Make sure to choose a pump with the power required for the job. It should also be able to handle a variety of samples.
