**2BV Series Liquid Ring Vacuum Pump Introduction:**
The 2BV series liquid ring vacuum pump, manufactured by Denair, includes the 2BV5, 2BV2, and 2BV6 models. These pumps are known for their superior performance, exceeding industry standards and widely used in pharmaceuticals, plastic machines, chemicals, oil & gas, and marsh gas industries.
Denair’s 2BV series features a compact design, with the rotors of 2BV2 and 2BV5 mounted directly on the motor shaft, eliminating the need for connectors. The pump casing is installed directly on the motor housing, simplifying alignment. Standard configurations include a bronze impeller for enhanced corrosion resistance and a mechanical seal to prevent leakage and reduce maintenance. The flexible vent design ensures optimal operation. The 2BV6 model, made from stainless steel, is better suited for harsh environments.

**Consistently High-Efficiency Operation:**
In limited installation spaces, the compact design of the 2BV series is a major advantage, being 30% smaller than typical Chinese-made liquid ring vacuum pumps. The low noise level eliminates the need for a muffler, contributing to a more compact and cost-effective solution. With low liquid consumption, the inclusion of a water separator allows for 50% recycling of operating liquid, further reducing operational costs. A closed-loop system minimizes waste water production and reduces the need for additional liquid. Condensate from the process media can be reused after proper filtration.

**Abundant Experience:**
As a supplement to standard pumps or single electric motors, complete 2BV sets can be supplied, including water separators, heat exchangers, and cavitation protection pipelines. These pumps can also be integrated with other systems like root vacuum pumps. Leveraging Denair's expertise in vacuum pumps, electric motors, and electrical control, we provide comprehensive solutions tailored to customer needs.

**Free Maintenance:**
The 2BV vacuum pump requires no maintenance due to its unique 100% oil-free design, eliminating the need for oil filters. Lubricating grease should be added every five years under normal conditions. Unlike packing seals, the mechanical seal does not require periodic adjustments.
