**2BV Series Liquid Ring Vacuum Pump Overview**
The 2BV series liquid ring vacuum pumps are manufactured by Denair, including models such as 2BV5, 2BV2, and 2BV6. These pumps exceed industry standards with outstanding performance and are widely used in pharmaceutical, plastic machinery, chemical, oil and gas, and other industries for suction applications.
Denair’s 2BV series features a compact design, with the rotors of 2BV2 and 2BV5 directly mounted on the motor shaft, eliminating the need for couplings. The pump casing is installed directly on the motor casing, making alignment unnecessary. The standard configuration includes a bronze impeller, which enhances corrosion resistance. A mechanical seal is also included to prevent leakage and reduce maintenance requirements. The patterned flexible vent ensures optimal operation. The 2BV6 model, made of stainless steel, is more suitable for harsh environments.
**High Efficiency & Compact Design**
In situations with limited installation space, the compact design of the 2BV series is a significant advantage, being 30% smaller than typical Chinese-made liquid ring vacuum pumps. The low noise level eliminates the need for a muffler, resulting in a more compact and cost-effective solution. Additionally, low liquid consumption is achieved through the use of a water separator that recycles 50% of the operating liquid, further reducing operational costs.
The closed-loop system minimizes wastewater production and reduces the need for supplementary liquid. Condensate from the transferred media can be recycled and reused.
**Experience & Customization**
With over 100 years of experience in designing vacuum pumps and air compressors, Denair offers reliable and high-quality solutions. The 2BV series can be supplied as a complete set, including a water separator, heat exchanger, and cavitation protection piping. It can also be combined with other vacuum pump systems like the roots vacuum pump. Based on Denair's strong expertise in vacuum pumps, electric motors, and electrical control systems, we provide comprehensive solutions tailored to customer needs.
**Low Maintenance & Eco-Friendly**
The 2BV vacuum pump requires minimal maintenance due to its 100% oil-free design, eliminating the need for oil filtration equipment. Lubricant grease should be added every five years under normal conditions. The mechanical seal, unlike packing seals, does not require regular adjustments.
