Powered by a 7.5 kW motor, the 2BVA5121 delivers an expanded 4.66 m³/min (279.6 m³/h) air capacity to satisfy demanding industrial-scale vacuum requirements.
Features standard DN65 inlet and outlet flanges, ensuring seamless integration and leak-proof fitting into large chemical and plant process piping systems.
Built with a rigid precision cast iron casing and standard mechanical seals, with optional SS304, SS316, or SS316L impellers for severe chemical environments.
A continuous 10 L/min seal liquid flow dissipates heat, eliminates dry friction, and stabilizes ultimate vacuum performance down to 33 mbar absolute.
Provides deep continuous vacuum for batch reactor solvent recovery, large-scale vacuum distillation columns, and pharmaceutical tray drying.
Efficiently powers sludge dewatering processes, municipal water treatment plants, and large suction priming systems.
Used extensively in paper mill felt dewatering, vacuum impregnation of timber, and continuous industrial fabric drying lines.
Delivers constant suction power for multi-head plastic/rubber vacuum extruders and large industrial CNC vacuum hold-down tables.
The 2BVA5121 (2BV5 121) delivers a maximum air capacity of 4.66 m³/min (279.6 m³/h), powered by a 7.5 kW motor at 1450 r.p.m. It features DN65 flanged connection ports, a 10 L/min operating fluid requirement, ≤69 dB(A) sound level, and reaches an ultimate limit vacuum of 33 mbar absolute (-0.097 MPa).
The 2BVA5121 upgrades to a larger DN65 flange port and a 7.5 kW motor, increasing air capacity to 4.66 m³/min (compared to 3.83 m³/min on the 5.5 kW 2BVA5111), making it suited for heavier industrial-scale distillation, filtration, and dewatering workflows.
While built with a robust precision cast iron casing as standard, the 2BVA5121 offers optional SS304, SS316, or SS316L stainless steel impellers and flow passages for processing corrosive vapors and chemical media.
The 2BVA5121 requires a continuous 10 L/min seal water circulation to maintain the liquid ring seal, dissipate heat, and protect internal components during continuous duty.
