2BVA2070 Liquid Ring Vacuum Pump
For distillation, filtration, dewatering or drying systems, provide gas composition, vapour and particle load, operating schedule, vessel volume and evacuation target. Confirm wetted materials, seal compatibility, connections, cooling, service-liquid supply or recirculation, separation and discharge treatment. Chemical or contaminated streams require review of compatibility and protective measures for the complete system. Verify continuous-duty capability, noise measurement conditions, leakage criteria and maintenance requirements for the proposed installation.

Key Technical Features & Performance Advantages
Performance Curve & Evacuation Planning
Review the listed capacity and motor rating with the model-specific performance curve at the required inlet pressure. Confirm electrical and service-liquid test conditions. Estimate evacuation time using vessel volume, gas load, leakage and complete system performance.
Connections & Pipework Review
Confirm port dimensions, connection type and adapters for the selected configuration. Review inlet pipe diameter, length, fittings and manifold gas loads. Assess pressure losses and available flow at the equipment connection.
Service-Liquid Supply & Heat Load
Confirm service-liquid type, temperature, flow and supply pressure for the proposed operating point. Review process heat and vapour load, separation, cooling, recirculation or discharge arrangements. A listed flow rate alone does not establish thermal performance or liquid consumption.
Operating Range & Cavitation Controls
Confirm the permitted pressure range and service-liquid conditions with the supplier. Review any anti-cavitation connection, bypass and protective controls included in the quotation. Verify the complete arrangement for the proposed duty rather than assuming an interface alone prevents damage.
Target Applications & Industry Uses
⚗️ Chemical Distillation & Filtration
For distillation, filtration or dewatering, provide gas composition, vapour and particle load, temperature, target pressure and duty cycle. Confirm wetted materials, seals, inlet protection, service-liquid compatibility and discharge treatment for the proposed process.
📄 Paper Pulp Dewatering & Processing
For pulp, felt or board processing, define gas load, working pressure, liquid carryover and operating schedule. Review separation, inlet protection, service-liquid supply or recirculation, cooling and cleaning requirements for the complete installation.
💊 Pharmaceutical & Industrial Drying
For pharmaceutical drying or contaminated vapour extraction, provide gas composition, vapour load and evacuation target. Review compatibility, separation, exhaust and liquid treatment, protective measures and any process validation requirements with the equipment integrator.
🪵 Wood Treatment & Impregnation
For timber treatment, veneer drying or tanning, provide process chemicals, gas and vapour load, vessel volume and evacuation time. Confirm material and seal compatibility, service-liquid management, controls and discharge treatment for the selected configuration.
Frequently Asked Questions (FAQ)
What suction capacity and motor power does the 2BVA2070 liquid ring pump offer?
Review the model-specific capacity, speed and motor data in the specification table and quotation under the stated electrical and test conditions. Confirm flow at the required working pressure using the performance curve and service-liquid conditions. Maximum capacity and limiting pressure should not be assumed to occur together.
What port size and connection type are used on the 2BVA2070 vacuum pump?
Confirm port dimensions, thread standard and adapters for the selected configuration in the dimensional drawing and quotation. Review pipe diameter, length, fittings and discharge arrangements; connection size alone does not establish system pressure loss or installation compatibility.
How does the 2BVA2070 compare with the 2BVA2061 model?
Compare both models at the same working pressure, electrical supply and service-liquid conditions using performance curves. Review motor load, connections, dimensions and permitted duty. A percentage difference in maximum capacity does not establish an equivalent change in evacuation time or suitability for continuous service.
Can the 2BVA2070 handle corrosive vapors and wet industrial gas streams?
Provide the exact gas composition, concentrations, temperature, vapour and particle load, and liquid carryover for compatibility review. Confirm all wetted materials, seals, service-liquid compatibility, separation and discharge treatment. A stainless steel option or mechanical seal alone does not establish suitability for every corrosive stream.
