Liquid Ring Vacuum Pump Small Capacity, 2BV6

Capacity 160 to 580 m3/h (95 to 340 ACFM)

Vacuum to 33 mbar abs. (1 inHgA)

NASH 2BV6 Liquid Ring Vacuum Pumps are single stage units designed for continuous operation, as vacuum pumps or compressors. With capacity ranging from 160 to 580 m3/h (95 to 340 ACFM), the 2BV6 series is used to extract and pump dry and moist gases, mainly air and air/vapor mixtures, in chemical, food & beverage, and other general industrial processes.

Key Characteristics:
  • Versatile Material and Motor Options
  • Rugged and Reliable Design
  • Quiet Operation
Material And Motor Choices
If your application demands all stainless steel construction for added corrosion resistance and/or special motor requirements such as enclosures, voltage, and frequency the 2BV6 is the right choice for your application. The 2BV6 pumps are available in both cast iron and 316 stainless steel construction and the pedestal design accepts most C-Faced motors.

Rugged And Reliable
We focused on durability and dependability when we developed these liquid-ring pumps. With a reinforced stainless steel shaft and sealed bearings, the 2BV6 can provide up to 20,000 hours of maintenance-free operation.

Quiet Operation
The NASH 2BV6 is expertly designed and manufactured to be quiet and vibration free. With sound pressure levels of less than 75 dBA, it complies with the strictest noise standards, eliminating the need for additional sound attenuating devices.
