2BVA2071 Liquid Ring Vacuum Pump
For filtration, dewatering, extrusion or drying systems, provide gas composition, vapour and particle load, duty cycle, vessel volume and evacuation target. Confirm wetted materials, seals, connections, cooling, liquid supply or recirculation, separation and discharge treatment. Assess liquid carryover and condensation requirements for the complete installation rather than assuming a stated supply rate provides protection. Verify continuous-duty capability, controls and maintenance requirements for the selected configuration.

Key Technical Features & Performance Advantages
Listed Displacement: 1.83 m³/min
The listed displacement is 1.83 m³/min (109.8 m³/h). Actual pumping speed and evacuation time depend on inlet pressure, gas load, service-liquid conditions and system resistance.
Listed Motor Power: 3.85 kW
The listed motor power is 3.85 kW. Confirm the motor rating, electrical supply and operating load for the selected configuration before specifying continuous operation.
Listed Service-Liquid Flow: 4.2 L/min
The listed service-liquid flow is 4.2 L/min. Confirm the required flow, temperature, liquid quality and supply arrangement for the process gas and operating pressure.
Cavitation Control Requires System Review
Confirm the available anti-cavitation connections and required piping for the supplied configuration. Operation near the service liquid vapor pressure requires pressure and temperature review; a connection alone does not guarantee protection.
Target Applications & Industry Uses
🧪 Heavy Chemical & Distillation Processes
For solvent recovery, reactors or vacuum crystallization, assess gas composition, vapor load, required pressure and service-liquid compatibility. Confirm materials, condensate handling and any hazardous-area requirements for the complete system.
🏭 Industrial Filtration & Dewatering
For slurry filtration or dewatering, size the pump against air leakage, filtration area and operating pressure. Review upstream separation and solids carryover limits before connecting it to mining, pulp or sludge systems.
Extrusion & Plastic Molding
For extrusion degassing, match pumping speed to gas release, moisture load and required process pressure. Confirm upstream filtration, condensate separation and material compatibility for the polymer and additives being processed.
⚙️ High-Volume Vapor Recovery & Drying
For vacuum drying or vapor recovery, calculate evacuation time and continuous gas load under the expected service-liquid conditions. Confirm condensers, separators and controls; timber, soil or power-station duties require individual system review.
Frequently Asked Questions (FAQ)
What is the maximum pumping speed and motor rating of the 2BVA2071 vacuum pump?
The page lists 1.83 m³/min (109.8 m³/h) displacement, 2860 r/min speed and 3.85 kW motor power. These are selection references; confirm the pumping-speed curve, inlet pressure, service-liquid temperature and motor configuration. The listed 33 mbar absolute limit is not a guaranteed pressure under process load.
How does the 2BVA2071 compare to the 2BVA2070 model?
The pages list 1.83 m³/min for 2BVA2071 and 1.33 m³/min for 2BVA2070. Compare their performance curves at the same inlet pressure, speed and service-liquid conditions; the listed displacement difference alone does not establish evacuation time or vapor-handling performance.
What is the required operating liquid flow rate for the 2BVA2071?
The listed service-liquid flow is 4.2 L/min. Confirm the required flow, inlet temperature, liquid quality and supply arrangement for the gas load and operating pressure, including monitoring to prevent loss of supply.
What suction port connection is fitted on the 2BVA2071?
The page lists DN40 connections. Confirm the supplied connection type, dimensions and applicable connection standard against the approved drawing; piping resistance and joint sealing must be assessed for the installation.
