**2BV Series Liquid Ring Vacuum Pump Overview**
The 2BV series liquid ring vacuum pumps, manufactured by Denair, include the 2BV5, 2BV2, and 2BV6 models. These pumps are designed to exceed industry standards with outstanding performance and are widely used in applications such as pharmaceuticals, plastic machines, chemical processing, oil and gas, and marsh gas industries.
Denair's 2BV series is known for its compact design, which makes it ideal for installations where space is limited. The rotors of the 2BV2 and 2BV5 models are directly mounted on the motor shaft, eliminating the need for connectors. Additionally, the pump case is installed directly onto the motor casing, removing the requirement for alignment. The standard configuration includes a bronze impeller that enhances corrosion resistance, and a mechanical seal that prevents leakage and reduces maintenance needs. The patterned flexible vent ensures optimal operational efficiency. The 2BV6 model, constructed from stainless steel, is more suitable for harsh environments.
**Key Features and Advantages:**
- **Compact Design:** 30% smaller than conventional Chinese-made liquid ring vacuum pumps, ideal for tight spaces.
- **Low Noise:** No muffler required, contributing to a quieter and more cost-effective system.
- **Low Liquid Consumption:** Equipped with a water separator that recycles 50% of the operating liquid, lowering operational costs.
- **Closed-loop System:** Reduces drain water production and minimizes the need for additional liquid supply.
- **Self-Absorption Function:** Simplifies operation and improves user experience.
- **100% Oil-Free Design:** Environmentally friendly and requires no oil changes or filters.
- **Long Lifespan & Low Maintenance:** Only one rotating part, reducing wear and tear and requiring lubricant grease every five years under normal use.
- **Mechanical Seal Standard:** Eliminates the need for periodic adjustments compared to packing seals.
- **Over 100 Years of Experience:** Ensures high-quality and reliable performance.
