Key Technical Features & Performance Advantages
Listed Displacement: 4.66 m³/min
The page lists 4.66 m³/min (279.6 m³/h) displacement and 7.5 kW motor power. Confirm the pumping-speed curve at the required inlet pressure, gas load and service-liquid conditions before selection.
Listed DN65 Connections
The page lists DN65 inlet and outlet connections. Confirm flange standards, dimensions, gasket selection and piping loads against the supplied drawing, and verify joint sealing during installation.
Material Options Require Confirmation
Confirm casing, impeller and seal materials for the ordered configuration. Any SS304, SS316 or SS316L option requires compatibility review for the gas, condensate, temperature and service liquid.
Listed Service-Liquid Flow: 10 L/min
The listed service-liquid flow is 10 L/min. Confirm the required flow, temperature and supply monitoring for the duty; the listed 33 mbar absolute limit is not a guaranteed pressure under process load, and dry running must be prevented.
Target Applications & Industry Uses
🧪 Chemical & Pharmaceutical Systems
For solvent recovery, distillation or tray drying, calculate gas and vapor loads at the required pressure. Confirm wetted materials, service-liquid compatibility, condensate handling and any pharmaceutical or hazardous-area requirements for the complete system.
🌊 Wastewater & Environmental Engineering
For vacuum-assisted sludge dewatering or suction priming, size the pump for air leakage, evacuation time and operating pressure. Confirm upstream separation, liquid carryover limits, service-liquid treatment and discharge handling for the specific installation.
🪵 Pulp, Paper & Textile Processing
For felt dewatering, timber impregnation or textile drying, assess moisture carryover, gas load and required pressure for the process equipment. Confirm separation, service-liquid management and compatibility with process chemicals.
⚙️ Plastic Extrusion & CNC Clamping
For extrusion degassing, match pumping speed to gas release and required process pressure. For CNC clamping, separately verify pressure differential, effective holding area and leakage; both duties require suitable filtration and liquid carryover control.
Frequently Asked Questions (FAQ)
What are the core performance specifications of the 2BVA5121 vacuum pump?
The page lists 4.66 m³/min (279.6 m³/h) displacement, 7.5 kW motor power, 1450 r/min speed, DN65 connections and 10 L/min service-liquid flow. Confirm the selected configuration and performance curve; the listed 33 mbar absolute limit is not a guaranteed pressure under process load. Any noise specification requires its test conditions.
How does the 2BVA5121 differ from the 2BVA5111 model?
The pages list 4.66 m³/min displacement, 7.5 kW motor power and DN65 connections for 2BVA5121, compared with 3.83 m³/min, 5.5 kW and DN50 for 2BVA5111. Compare performance curves under the same operating conditions, installation dimensions and actual gas load before selecting a model.
What corrosion-resistant material options are available for the 2BVA5121?
Confirm which casing, impeller, seal and other wetted-material options are available for the ordered configuration. Any SS304, SS316 or SS316L option requires compatibility review for the chemicals, concentration, temperature, condensate and service liquid; the material name alone does not establish suitability.
What is the recommended operating liquid flow rate for the 2BVA5121?
The listed service-liquid flow is 10 L/min. Confirm required flow, inlet temperature, liquid quality and once-through or recirculation arrangement for the operating pressure and gas load, including cooling and supply monitoring for continuous duty.
