Vacuum Technology
Air jet vacuum pump
Air jet vacuum pumps type lvp1 are based on proven jet pump technology and often used when no steam is available as motive medium.
Applications
- When no steam is available as motive medium for a steam jet vacuum pump required to produce a vacuum of 40 to 5 mbar.
- When a liquid ring pump is available with a suction capacity sufficient to handle the motive air of the air jet pump and when a suction pressure below 40 mbar is to be produced.
- When a vacuum of 40 to 5 mbar is to be produced and simple installation with low capital cost is important.
- When only a small suction capacity at a suction pressure of 40 to 50 mbar is required and cooling water at low temperature is available, because under these circumstances, the power consumption of the liquid ring vacuum pump is relatively low.
Mode of operation
Air jet vacuum pumps use atmospheric air as motive medium. Backed by a liquid ring vacuum pump which produces an intermediate vacuum of 50 to 100 mbar, the air jet vacuum pump can reach a suction pressure of 5 mbar, depending on design and operating conditions.
Whenever it is a question of low energy consumption, it is better to connect a steam jet pump with condenser to the suction side of the liquid ring vacuum pump, whereby the motive medium (steam) of the jet pump is condensed and does not load the liquid ring vacuum pump as is the case with an air jet pump.
Advantages
- No moving parts
- Maintenance-free
- Can be installed in virtually all situations
- Quickly and easily put into operation
- Almost unlimited life, when a suitable material of construction is chosen
- Can be manufactured from various materials of construction
- Low acquisition costs
