2BH1 840

Product catalog summary

Overview: This technical data sheet provides detailed specifications and operational guidelines for the G-BH series pumps, which function as both vacuum pumps and compressors. The document outlines performance characteristics, motor specifications, and compliance with industry standards.

Specifications: The G-BH pumps are designed for continuous operation across the entire performance curve range. They are equipped with motors that have a protection category of IP 55 and insulation class F. The pumps are UL and CSA approved, ensuring compliance with safety and performance standards.

Performance Curves: The performance data is based on air at 15°C and atmospheric pressure of 1013 mbar, with a tolerance of ±10%. The total pressure differences are applicable for suction and ambient temperatures up to 25°C. For conditions outside these parameters, consultation with the manufacturer is recommended.

Motor Specifications: The motors are available in various voltage configurations, including fixed voltage and voltage range options. They are suitable for operation with frequency converters up to 460 V. The frequency tolerance is ±2% maximum, and the motors comply with EN 60034-1 standards.

Compliance and Standards: The G-BH pumps meet the 2006/42/EC (machinery) and 2006/95/EC (low voltage) directives. They also adhere to the EN 60034-1 norm for rotating electrical machines. The sound pressure level is measured according to EN ISO 3744 standards.

Additional Information: The document notes that performance may vary if IE2 motors are used and advises referring to specific data sheets for those configurations. Relief valves are available for limiting differential pressure, and changes to performance data may occur without prior notice.
