Mag Drive Liquid Ring Vacuum Pump Small Capacity, 2BM1

Capacity 100 to 900 ACFM (190 to 1,400 m3/h)

Vacuum to 1 inHgA (33 mbar abs.)


The NASH 2BM Mag Drive liquid ring vacuum pump and compressor series provides reliable, leak free performance for applications requiring the highest levels of safety. The 2BM1 model offers an inlet and discharge on both the Drive End (DE) and Non-Drive End (NDE). With a hermetically sealed pump body and capacity from 100 to 900 ACFM (190 to 1,400 m3/h) the 2BM1 liquid ring pump/compressor is an ideal match for process applications in the chemical, pharmaceutical, petrochemical, and food industries.

Key Characteristics:
  • Reliable Hydraulics and Proven Engineering
  • Hermetically Sealed, Leak-Free Solution
  • Minimal Wear and Maintenance
Reliable Hydraulics, Proven Engineering
Based on the existing 2BE1 pump and compressor design, the 2BM1 series delivers proven performance and reliability to applications that require leak free performance.

Operates as a vacuum pump and compressor with a discharge pressure range of 36 psia (2.5 bar abs.)
Some applications require vacuum and compression in one process. Instead of handling the gas with two separate machines, our liquid ring vacuum pump and compressor models can do the job with only one pump - reducing cost and simplifying installation.

Safe Solution, No Leaks
Through a magnetic drive with static o-ring seals the 2BM1 vacuum pump and compressor achieves non-contact torque transmission, allowing for a hermetically sealed pump body. This eliminates leaks, making the 2BM1 an ideal solution for process applications that handle toxic or explosive gases or liquid, and applications that must comply with the strictest environmental regulations. ATEX Certified pumps are available.

Minimal Wear and Maintenance
2BM pumps and compressors are completely enclosed and have no rotating shaft seals, eliminating wear and maintenance issues associated with mechanical seals. The pump's operating fluid ensures optimum lubrication and cooling of the friction bearings and magnetic coupling, eliminating the need for grease lubrication.
  • Shaft Sealing: Magnetic seal
  • Materials: Cast Iron, Stainless Steel
  • Flat Sided Porting
