Product Description

2BV series water ring vacuum pumps and compressors

Product Description

2BV2, 2BV5, are suitable for pumping dry and wet gases, mainly non-flammable, non-corrosive atmospheres and atmospheric/vapor mixtures. 2BV6 is suitable for pumping flammable and explosive gases and for flammable and explosive working environments. The working fluid is usually water. Stainless steel pumps are suitable for applications with more demanding corrosion and sanitary requirements. 2BV vacuum pumps are used in the rough vacuum range and the ultimate vacuum is determined by the saturated vapor pressure of the working fluid.
Ultimate vacuum
The ultimate vacuum depends on the working temperature and the type of working fluid used. Please note the following points: a pump without cavitation protection, suction pressure must not be less than 80 mbar, this is to avoid the water temperature of 15 ºC, the temperature of the pumped dry air at 20 ºC in the pump caused by cavitation, the higher the temperature, depending on the working fluid saturated vapor pressure, the minimum suction pressure allowed will also be higher. The higher the temperature, the lower the suction capacity. Note: 2BV vacuum pumps operating for a long time under the minimum allowable suction pressure will cause damage to the pump.
Maximum exhaust pressure
The maximum allowable exhaust pressure is 1200 mbar for 2BV2 vacuum pumps and 1300 mbar for 2BV5 and 2BV6 vacuum pumps when using working fluid according to the flow rate in the table.
Pumped gases or vapors
The pumped gas or gas/vapor mixture is not allowed to contain CHINAMFG particles, but a small amount of suspended matter or liquid is allowed. Table 2 shows the maximum amount of water allowed to be drawn in from the suction flange. When pumping hot gases or steam above 80°C, it is recommended to use 2 times the standard flow rate of working fluid

Can Vacuum Pumps Be Used for Chemical Distillation?

Yes, vacuum pumps are commonly used in chemical distillation processes. Here’s a detailed explanation:

Chemical distillation is a technique used to separate or purify components of a mixture based on their different boiling points. The process involves heating the mixture to evaporate the desired component and then condensing the vapor to collect the purified substance. Vacuum pumps play a crucial role in chemical distillation by creating a reduced pressure environment, which lowers the boiling points of the components and enables distillation at lower temperatures.

Here are some key aspects of using vacuum pumps in chemical distillation:

1. Reduced Pressure: By creating a vacuum or low-pressure environment in the distillation apparatus, vacuum pumps lower the pressure inside the system. This reduction in pressure lowers the boiling points of the components, allowing distillation to occur at temperatures lower than their normal boiling points. This is particularly useful for heat-sensitive or high-boiling-point compounds that would decompose or become thermally degraded at higher temperatures.

2. Increased Boiling Point Separation: Vacuum distillation increases the separation between the boiling points of the components, making it easier to achieve a higher degree of purification. In regular atmospheric distillation, the boiling points of some components may overlap, leading to less effective separation. By operating under vacuum, the boiling points of the components are further apart, improving the selectivity and efficiency of the distillation process.

3. Energy Efficiency: Vacuum distillation can be more energy-efficient compared to distillation under atmospheric conditions. The reduced pressure lowers the required temperature for distillation, resulting in reduced energy consumption and lower operating costs. This is particularly advantageous when dealing with large-scale distillation processes or when distilling heat-sensitive compounds that require careful temperature control.

4. Types of Vacuum Pumps: Different types of vacuum pumps can be used in chemical distillation depending on the specific requirements of the process. Some commonly used vacuum pump types include:

– Rotary Vane Pumps: Rotary vane pumps are widely used in chemical distillation due to their ability to achieve moderate vacuum levels and handle various gases. They work by using rotating vanes to create chambers that expand and contract, enabling the pumping of gas or vapor.

– Diaphragm Pumps: Diaphragm pumps are suitable for smaller-scale distillation processes. They use a flexible diaphragm that moves up and down to create a vacuum and compress the gas or vapor. Diaphragm pumps are often oil-free, making them suitable for applications where avoiding oil contamination is essential.

– Liquid Ring Pumps: Liquid ring pumps can handle more demanding distillation processes and corrosive gases. They rely on a rotating liquid ring to create a seal and compress the gas or vapor. Liquid ring pumps are commonly used in chemical and petrochemical industries.

– Dry Screw Pumps: Dry screw pumps are suitable for high-vacuum distillation processes. They use intermeshing screws to compress and transport gas or vapor. Dry screw pumps are known for their high pumping speeds, low noise levels, and oil-free operation.

Overall, vacuum pumps are integral to chemical distillation processes as they create the necessary reduced pressure environment that enables distillation at lower temperatures. By using vacuum pumps, it is possible to achieve better separation, improve energy efficiency, and handle heat-sensitive compounds effectively. The choice of vacuum pump depends on factors such as the required vacuum level, the scale of the distillation process, and the nature of the compounds being distilled.
