2BE4 series

Product catalog summary

Overview: The NASH 2BE4 and P2620 series are liquid ring vacuum pumps and compressors designed for durability and efficiency in demanding environments such as paper, power, mining, and chemical industries. These models feature a polyisoprene-lined body for enhanced corrosion and erosion resistance, with options for stainless steel and epoxy coatings for more aggressive applications.

Key Features and Benefits:

Corrosion Resistance: Polyisoprene lining and optional stainless steel components provide superior resistance to corrosion.
Operational Flexibility: The center partition allows each half of the pump to operate at different vacuum levels, reducing the number of pumps needed and saving space and installation costs.
Quiet Operation: Sound levels range from 72 to 85 dB(A), ensuring quieter operation even for larger models.
Installation Flexibility: Multiple inlet and discharge configurations, including top discharge capability, minimize floor space requirements.
Performance and Maintenance: Large inspection ports facilitate easy maintenance, and the pumps are 100% performance tested before shipment.

Technical Specifications:

Vacuum Range: Up to 160 mbar abs.
Compressor Pressure: Up to 2.5 bar abs.
Suction Capacity: Ranges from 2,500 to 39,000 m³/hr.
Construction Materials: Available in ductile iron, stainless steel, or a combination of both.

Design and Performance: The NASH 2BE4 series is an upgrade from the 2BE3 series, featuring optimized shaft bearings for increased flexibility and improved lubrication, reducing energy requirements by 6 to 8%. The unique inlet configuration supports both top and side arrangements, accommodating installations with limited headroom.

Additional Products and Services: Gardner Denver Nash offers a wide range of liquid ring compressors and pumps, including the Vectra XL, GL, and SX series, designed for various applications and high back pressure requirements. The company provides global service centers to ensure efficient and long-lasting pump operation.
