Key Technical Features & Performance Advantages

1.33 m³/min High-Throughput Suction

Delivers superior gas evacuation rates (79.8 m³/h) powered by a 2.35 kW motor, significantly reducing cycle time during bulk vessel pull-down and continuous vacuum drying.

🔩

DN40 Enlarged Threaded Ports

Upgraded DN40 port dimensions minimize pressure drop across long inlet lines, allowing seamless coupling to high-volume chemical manifolds and industrial vacuum headers.

💧

Optimum 2.5 L/min Liquid Ring Cooling

Operates with a precise 2.5 L/min working fluid flush to absorb process heat, collapse condensable steam carryover, and maintain stable sealing without fluid wastage.

🛡️

Anti-Cavitation Line Integration

Equipped with an external anti-cavitation port that prevents destructive vapor bubble implosions when operating long hours near maximum limit vacuum (33 mbar abs).

Target Applications & Industry Uses

⚗️ Chemical Distillation & Filtration

Handles continuous extraction of condensable chemical vapors, solvent evaporation units, mineral slurry filtration, and fertilizer plant dewatering.

📄 Paper Pulp Dewatering & Processing

Removes high-volume moisture from paper pulp sheets, felt washing lines, and cardboard vacuum shaping systems.

💊 Pharmaceutical & Industrial Drying

Essential for industrial rotary vacuum dryers, tray drying ovens, active pharmaceutical ingredient (API) extraction, and soil vapor remediation.

🪵 Wood Treatment & Impregnation

Provides deep vacuum evacuation for timber preservative pressure vessels, plywood veneer drying, and leather vacuum tanning chambers.

Frequently Asked Questions (FAQ)

What suction capacity and motor power does the 2BVA2070 liquid ring pump offer?

The 2BVA2070 provides a high air displacement of 1.33 m³/min (79.8 m³/h) at 2850 r.p.m., driven by a heavy-duty 2.35 kW motor while achieving an ultimate vacuum depth of 33 mbar absolute (-0.097 MPa).

What port size and connection type are used on the 2BVA2070 vacuum pump?

The 2BVA2070 features DN40 threaded connection ports, providing lower fluid resistance and seamless integration into medium-to-large industrial piping systems.

How does the 2BVA2070 compare with the 2BVA2061 model?

The 2BVA2070 offers a 54% increase in pumping speed over the 2061 (1.33 m³/min vs. 0.86 m³/min) and upgrades the drive power to 2.35 kW with DN40 porting, suited for large-scale continuous evacuation applications.

Can the 2BVA2070 handle corrosive vapors and wet industrial gas streams?

Yes, with standard mechanical seals and optional SS304/SS316L stainless steel wet parts, the 2BVA2070 easily handles saturated steam, corrosive chemical vapors, and liquid carryover.
