Arrival of Elmo Rietschle G-BH1N Vacuum Pump

Arrival of Elmo Rietschle G-BH1N Vacuum Pump

AVA has successfully received the Elmo Rietschle G-BH1N 2BH1900-1AQ17 vacuum pump. This is one of the most powerful and widely used models in the G-BH1N series, trusted by customers for applications requiring stable vacuum performance and continuous operation.

Working Principle

The G-BH1N operates based on the side channel principle. When the motor rotates, the impeller continuously transfers energy to the airflow, creating a pressure difference between the suction and discharge sides.

Thanks to the non-contact design between the impeller and housing, the pump ensures:

• Minimal wear
• Low noise operation
• High durability and reliability

Key Advantages

• Robust design, suitable for 24/7 continuous operation
• IE3 high-efficiency motor for energy savings
• Low noise level: 74 dB(A) at 50 Hz
• Flexible installation: horizontal or vertical (with spring elements)
• IP55 protection class, suitable for harsh industrial environments
• Easy maintenance with low long-term operating costs
• Versatile: suitable for both vacuum and pressure applications

Typical Applications

The G-BH1N series is widely used in:

• Printing & packaging (paper handling, vacuum forming)
• Food & beverage (powder conveying, drying processes)
• Wastewater treatment (aeration, air blowing)
• Mechanical engineering (vacuum clamping)
• Medical & laboratory systems (central vacuum systems)
• Agriculture & crop drying
• Dust extraction and industrial ventilation systems
