GOFLEX PUMP

2BVA5161 Liquid Ring Vacuum Pump

The GOFLEX 2BVA5161 (2BV5 161) is a liquid ring vacuum pump for review against your required gas load and working pressure. Compare the listed displacement, motor rating and rotational speed under the same electrical and test conditions. Request the performance curve and confirm service-liquid type, temperature, flow and supply arrangement; maximum displacement and limiting pressure are separate selection values unless the curve establishes the operating point.

For chemical processing, dewatering, paper pulp or power station systems, provide gas composition, vapour and particle load, duty cycle, vessel volume and evacuation target. Confirm casing and impeller materials, seal compatibility, flange dimensions, cooling, liquid separation, recirculation or discharge treatment, and protective controls. Assess compatibility and liquid carryover requirements for the complete installation. Verify continuous-duty capability, noise measurement conditions and maintenance requirements for the quoted configuration.

Key Technical Features & Performance Advantages

🚀

Listed Displacement: 8.33 m³/min

The page lists 8.33 m³/min (499.8 m³/h) displacement and 15 kW motor power. Confirm the pumping-speed curve at the required inlet pressure, gas load and service-liquid conditions before selection.

⚙️

Listed Operating Speed: 970 r/min

The listed operating speed is 970 r/min. Confirm the motor supply and selected configuration; operating temperature, wear and service life depend on the installation, load, service liquid and maintenance conditions.

🛡️

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: 20 L/min

The listed service-liquid flow is 20 L/min. Confirm flow, temperature and supply monitoring, and review cavitation controls for the operating pressure. Flow alone does not guarantee protection or the listed 33 mbar absolute limit under process load.

Target Applications & Industry Uses

⛏️ Mining & Mineral Dewatering

For rotary vacuum filtration or mineral slurry dewatering, size against filtration area, air leakage and operating pressure. Confirm upstream separation, abrasive solids carryover limits, service-liquid quality and discharge handling for the specific plant.

🧪 Heavy Chemical & Distillation Towers

For reactors, distillation columns or solvent recovery, calculate continuous gas and vapor loads at the required pressure. Confirm materials, condensate handling, service-liquid compatibility and any hazardous-area requirements for the complete system.

🪵 Paper Mills & Large Textile Plants

For pulp dewatering, timber impregnation or textile drying, match pumping speed to gas load and equipment pressure requirements. Confirm moisture separation, process-chemical compatibility and service-liquid management before selection.

⚡ Power Generation & Municipal Utilities

For condenser water-box priming or vacuum-assisted sludge extraction, calculate air leakage, evacuation time and required pressure. Confirm liquid carryover controls, operating sequence and service-liquid treatment for the power-plant or municipal installation.

Frequently Asked Questions (FAQ)

What are the core technical specifications of the 2BVA5161 vacuum pump?

The page lists 8.33 m³/min (499.8 m³/h) displacement, 15 kW motor power, 970 r/min speed and 20 L/min service-liquid flow. Confirm inlet and outlet connection sizes against the supplied drawing and verify the performance curve. The listed 33 mbar absolute limit is not a guaranteed pressure under process load; any noise specification requires its test conditions.

Why does the 2BVA5161 operate at 970 r.p.m. compared to smaller models?

The page lists 970 r/min for this configuration. Confirm the motor pole count, supply frequency and rated speed against the supplied motor data. Speed alone does not establish wear, vibration, noise or service life; compare the complete pump configuration and operating conditions.

What material options are available for aggressive gas applications?

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 operating liquid flow rate is required for the 2BVA5161?

The listed service-liquid flow is 20 L/min. Confirm required flow, inlet temperature, liquid quality and once-through or recirculation arrangement for the operating pressure and gas load. Review cooling, supply monitoring and cavitation controls; flow alone does not guarantee protection against overheating.
