Reference data for standard, non-explosion-proof 2BV2 / 2BV5 configurations, from the supplied replacement specification sheet. Motor protection: IP54. Vacuum is listed in the source as 33 mbar (−0.098 MPa); the pressure reference and test conditions must be confirmed before selection. Maximum gas capacity and limiting vacuum are separate ratings. Flow values in m³/min and m³/h are reproduced as supplied, including rounding. Weights are reference product weights, not packed shipping weights. Confirm the motor, frequency, material, connection dimensions and final weight for your selected configuration. Explosion-proof 2BV2-Ex and 2BV6 rows are not included.

Match the pump to the operating point.

The rotating impeller forms a liquid ring. Changing chamber volumes draw in gas, compress it and discharge it through the outlet.

Selection depends on required gas capacity at the operating vacuum, working-liquid temperature and process conditions. For extrusion and other industrial applications, review these requirements with HENVO.

APPLICATION FIT

Start with your process.

The duty defines the configuration. Start with what your process needs.

Industrial vacuum

Match rough-vacuum duties to the capacity needed at your operating pressure.

Wet gas handling

For wet gases and gas–vapour mixtures, share composition and temperature for a suitability review.

Continuous operation

Review the duty cycle, working-liquid supply and circulation arrangement together.

Standard 2BV2/2BV5 selection is described for non-flammable, non-corrosive gas duties. Special gas composition or hazardous environments require a separate configuration review.
