BELL Liquid-ring Vacuum pumps are mainly used in the following industries: Fibre cement; Paper; Card- and Insulationboard ; Process Technology; A constructive advantage is that impure gases which are mixed with a certain amount of fluids and/or solids can be pumped without influencing the function and the efficiency of the vacuum pump negatively.

Sizing Vacuum Pumps - VTech

pumps where smaller ones will sufficient. High capacity pumps have other applications, such as those using large vacuum chambers, but in a smaller refrigeration circuit, a 100 m3/h pump will generate only 30% more pumping capacity at 5 times the size of a 20 m3/h pump. In business language, that is a poor return on investment.

Liquid Ring Technology - Liquid ring vacuum pumps

The liquid ring vacuum pump has only one moving part -- a balanced rotor that runs without any metal-to-metal rubbing contact. Such simplicity is possible because all functions of mechanical pistons or vanes are actually performed by a rotating band of water which serves as a liquid compressant.

An Introduction to Vacuum Pumps - Vacaero

Jan 13, 2016 · When designing or operating a vacuum system, it is critical to understand the function of the vacuum pumps. We will review the most common types of vacuum pumps, their principles of operation and where in the system they are used. Vacuum pumps are categorized by their operating pressure range and as such are classified as primary pumps, booster pumps or secondary pumps.

Air Blowers selection precautions- Vacuum Pump - EVP .

The air blower has dual functions of blowing and suction, one machine can be used for suction or blowing, which is equivalent to the function of rotary vane vacuum pump; the blower operates with little oil or no oil, and the output air is clean; compared with centrifugal fan and medium pressure fan, the pressure of blower is much higher, which is more than ten times of centrifugal fan.

Effect of Service Water Temperature on Capacity of Liquid .

The temperature of the sealing fluid (in this case water) can have a dramatic effect on the capacity of a liquid ring vacuum pump. The performance data, which DEKKER Vacuum Technologies publishes, are based on using 60°F water as the sealing liquid for the vacuum pump.
