2BVA5110 Liquid Ring Vacuum Pump
For chemical processing, pharmaceutical equipment or dewatering systems, provide gas composition, vapour and particle load, vessel volume and evacuation target. Confirm casing and impeller materials, seal compatibility, flange dimensions, cooling, liquid separation and recirculation or discharge treatment for the selected configuration. Pharmaceutical use requires application-specific validation with the equipment integrator. Verify continuous-duty capability, noise measurement conditions, controls and maintenance requirements before ordering.

Key Technical Features & Performance Advantages
Listed Operating Speed: 1450 r/min
The listed operating speed is 1450 r/min. Confirm the motor supply and selected configuration; noise and seal life depend on the installation, operating load and maintenance conditions.
Listed DN50 Connections
The page lists DN50 inlet and outlet connections. Confirm flange standards, dimensions, piping loads and system resistance against the supplied drawing before installation.
Material Options Require Confirmation
Confirm the casing, impeller and seal materials for the ordered configuration. Any SS304, SS316 or SS316L option requires a compatibility review for the gas, condensate and service liquid.
Listed Service-Liquid Flow: 6.7 L/min
The listed service-liquid flow is 6.7 L/min. Confirm flow, temperature and supply monitoring for the duty; pumping capacity and vapor handling depend on operating conditions, and dry running must be prevented.
Target Applications & Industry Uses
🧪 Chemical & Pharmaceutical Processing
For filtration, evaporation or reaction degassing, confirm gas composition, solvent compatibility, vapor load and required pressure. Pharmaceutical duties also require a review of contamination controls, cleaning and process-specific qualification.
🌊 Wastewater Treatment & Environmental
For sludge dewatering or environmental extraction, match pumping speed to air leakage and gas load at the operating pressure. Confirm upstream separation, solids carryover limits, service-liquid treatment and discharge requirements.
🛠️ CNC Machining & Vacuum Clamping
For vacuum tables or hold-down fixtures, calculate holding force from pressure differential, effective clamping area and leakage. Confirm workpiece porosity, filtration, liquid carryover control and loss-of-vacuum safeguards before selection.
🏭 Industrial Evaporation & Distillation
For evaporation, distillation or priming, size the complete system for vapor load, evacuation time and operating pressure. Food or dairy duties require an individual review of product-contact risks, materials, cleaning and liquid handling.
Frequently Asked Questions (FAQ)
What are the core technical specifications of the 2BVA5110 vacuum pump?
The page lists 2.75 m³/min (165 m³/h) displacement, 4 kW motor power, 1450 r/min speed, DN50 connections and 6.7 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.
How does the 2BVA5110 (2BV5 series) differ from the 2BV2 series?
The 2BVA5110 page lists 1450 r/min speed and DN50 connections. Compare dimensions, performance curves, motor ratings and connection drawings with the specific 2BV2 model. Lower speed alone does not establish a noise level or service-life advantage.
What material customization options are available for corrosive chemical duty?
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 2BVA5110?
The listed service-liquid flow is 6.7 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.
