Powered by a 15 kW motor, the flagship 2BVA5161 provides unmatched 8.33 m³/min (499.8 m³/h) suction capacity for heavy-duty industrial vacuum processing.
Operating at 970 r.p.m. reduces mechanical friction, lowers operating temperatures, and minimizes wear on large internal impellers for extended service life.
Built with a 300 kg heavy-duty precision cast iron housing and mechanical seals, offering SS304, SS316, or SS316L impellers for severe chemical gas streams.
Continuous 20 L/min seal liquid flow absorbs gas vapor heat, prevents cavitation, and maintains stable 33 mbar absolute limit vacuum depth.
Provides constant high-volume suction for large rotary vacuum filters, iron ore slurry processing, and coal washing filtration plants.
Handles demanding continuous gas evacuation in industrial chemical reactors, multi-stage distillation columns, and bulk solvent recovery.
Extensively deployed in heavy paper pulp dewatering presses, timber vacuum impregnation vessels, and industrial textile drying systems.
Powers condenser water box priming in thermal power plants and municipal wastewater sludge vacuum extraction systems.
The 2BVA5161 (2BV5 161) delivers a maximum air capacity of 8.33 m³/min (499.8 m³/h), powered by a 15 kW motor operating at a low-noise speed of 970 r.p.m. It features heavy-duty flanged connection ports (DN80/DN100), a 20 L/min operating liquid flow rate, noise levels ≤74 dB(A), and achieves an ultimate limit vacuum of 33 mbar absolute (-0.097 MPa).
The 2BVA5161 utilizes a 6-pole 970 r.p.m. motor to lower peripheral velocity on its larger impeller. This low-speed design reduces mechanical wear, minimizes vibration, lowers noise (≤74 dB), and ensures long-term operational stability under heavy continuous industrial loads.
The 2BVA5161 features a precision cast iron housing as standard, with optional SS304, SS316, or SS316L stainless steel impellers and flow components designed to withstand severe corrosion in chemical, mining, and industrial vapor handling systems.
The 2BVA5161 requires a continuous 20 L/min operating liquid circulation to maintain the liquid ring seal, provide maximum thermal dissipation, and prevent mechanical overheating during deep vacuum operation.
