 Summary

2BVA series vacuum pumps are suitable for gas and water vapor extraction. The suction pressure can reach 33 mbar absolute pressure (97% vacuum degree). When the suction pressure of the vacuum pump is lower than 80 mbar for a long time, the cavitation protection pipe should be connected to protect the pump. If equipped with an air ejector, the suction pressure can reach 10 mbar, and the ejector can be directly installed on the vacuum pump. When used as a compressor, the maximum pressure is 0.26 MPa (absolute pressure).
Structure and characteristics:
Coaxial direct connection design of pump saves space and is easy to install.
Mechanical seal is used as standard configuration, eliminating leakage and easy maintenance.
It runs smoothly and the noise can be as low as 62 decibels.
Unified corrosion resistance design, bronze impeller improves the corrosion resistance of the pump, such as the use of stainless steel material is more suitable for more demanding applications.
Unique flexible exhaust design, will not produce over-compression, ensuring the best efficiency of 2BV in its performance range.

Examples of type selection:

(1) Design point parameters:

Inhalation v=100m3/h

Inhalation pressure P1 = 40mbar

(2) The remaining parameters are in the same standard state (see note)

Selection of a curve closest to the design point

(3) 71V in this case

Find out the corresponding product type according to the curve number

(i.e. fixed loan number, but limited to standard type)

For example, the pump type can be found in 71V.

2BV2071-ONC06-1p

Note: The performance curve is obtained under the condition of saturated air at 20 C, working fluid temperature 15 C and exhaust pressure 1013 mba. The performance allowable difference is 10%. The performance curve of the air ejector is on the left side of the figure.
