Upgraded internal geometry combined with a 1.45 kW motor boosts volumetric pumping efficiency to 0.86 m³/min, handling larger gas loads without sacrificing vacuum depth.
Enlarged DN32 threaded suction and discharge ports reduce piping friction losses, ensuring faster evacuation response times across medium-sized processing vessels.
Inherently impervious to steam, moisture carryover, and light condensable fluids. Seals and internal passages resist scale build-up and mechanical degradation.
Includes built-in porting for a dedicated anti-cavitation line. Protects the impeller and casing from erosion during long cycle runs near the 33 mbar absolute vacuum limit.
Provides robust vacuum degassing for continuous twin-screw plastic extruders, PET sheet extrusion lines, and rubber compounding systems.
Efficiently extracts moisture and solvent vapors in vacuum distillation units, chemical filtration equipment, and batch drying processes.
Utilized in continuous automated vacuum packaging machinery, central dairy degassing systems, and fruit juice impregnation units.
Handles condenser water box evacuation, municipal water intake pump priming, and transformer oil vacuum filtration lines.
The 2BVA2061 increases suction displacement by nearly 91% (0.86 m³/min vs. 0.45 m³/min) and is equipped with a stronger 1.45 kW motor and enlarged DN32 threaded ports, making it ideal for higher-volume processing lines.
Its ability to handle continuous moist air, condensable vapors, and fine polymer particulates without oil contamination ensures uninterrupted vacuum degassing during plastic resin extrusion.
The 2BVA2061 requires a continuous working liquid supply of 2.0 L/min to establish stable liquid ring seals and maintain peak thermal cooling during operation.
Yes, by connecting the equipped anti-cavitation pipeline, the pump equalizes internal pressure during long-term operation near 33 mbar absolute, extending impeller service life.
