Powered by an 11 kW motor, the 2BVA5131 produces 6.66 m³/min (399.6 m³/h) air volume, efficiently handling heavy gas loads and large-scale vapor removal.
Equipped with standardized DN65 inlet and outlet flanges, ensuring simple, leak-proof integration into large-diameter process and utility pipelines.
Constructed with a heavy-duty precision cast iron housing and mechanical seals, offering SS304, SS316, or SS316L impellers for hostile gas environments.
Continuous 15 L/min fluid circulation prevents dry running, cools internal components, and maintains steady 33 mbar absolute ultimate vacuum depth.
Handles demanding vacuum requirements for multi-stage chemical distillation, batch reactor solvent recovery, and pharmaceutical drying systems.
Widely utilized in high-volume paper pulp dewatering, wood vacuum impregnation, and industrial textile moisture extraction.
Delivers steady vacuum for large rotary drum filters, iron ore dewatering processes, and coal washing vacuum systems.
Provides strong suction force for municipal wastewater sludge dewatering and high-capacity water pump priming in power stations.
The 2BVA5131 (2BV5 131) features a maximum air suction capacity of 6.66 m³/min (399.6 m³/h), powered by an 11 kW motor operating at 1430 r.p.m. It incorporates DN65 flanged connection ports, a 15 L/min liquid ring circulation rate, sound levels of ≤73 dB(A), and achieves an ultimate limit vacuum of 33 mbar absolute (-0.097 MPa).
The 2BVA5131 upgrades to a robust 11 kW motor, increasing suction performance to 6.66 m³/min (over 40% higher than the 4.66 m³/min capacity of the 7.5 kW 2BVA5121), making it tailored for high-volume paper pulp dewatering, large chemical distillation columns, and mining filtration systems.
Built with a durable precision cast iron casing as standard, the 2BVA5131 offers customizable SS304, SS316, or SS316L stainless steel impellers and wetted parts to resist aggressive chemicals, vapors, and organic solvents.
The pump requires a continuous operating liquid flow of 15 L/min to maintain the liquid ring seal, cool internal mechanical components, and absorb process vapor heat during heavy industrial operations.
