คุณสมบัติพื้นฐาน
Oil Free Operation, Stainless Steel Impeller, 0.45-8.33 m³/min Suction Capacity
The 2BV series is a single-stage, direct-coupled water ring vacuum pump designed to replace traditional SK, 2SK, W, WY, and WL series pumps. It operates isothermally, making it ideal for handling flammable, explosive, or dust-laden gases. With compact structure, low noise, and high reliability, it is widely used in vacuum filtration, conveying, degassing, evaporation, and drying processes.
- Direct Motor Coupling: Compact design, easy installation and maintenance
- Stainless Steel Impeller: Standard in all models; 2BV2 series also includes stainless steel discs
- John Crane Mechanical Seal: High reliability and long service life
- Flexible Exhaust Port Design: Prevents over-compression, ensures optimal efficiency
- Cavitation Protection Interface: Standard on all models for extended operation at极限真空
- YE2 Series High-Efficiency Motor: IP54 / IP55 protection, Class F insulation
- NTN / NSK Imported Bearings: High durability and smooth operation
- PTFE Seals Available: For harsh chemical environments
- Explosion-Proof Versions: 2BV2-Ex and 2BV6 series for flammable/explosive gas applications
