Important Notices
  • Suitable for pumping gas and water vapor; do not pump corrosive gases without selecting corresponding material configuration
  • When working under suction pressure close to limit vacuum, must connect cavitation protection pipe to avoid damage
  • Control working fluid flow according to actual situation; if not recycled, flow should be doubled as listed in parameter table
  • Install in well-ventilated area, ensure pump is level and stable with sufficient maintenance space
  • For explosion-proof models, ensure installation environment meets explosion-proof grade requirements
  • Regularly check mechanical seal and bearing status, replace lubricating oil and seals per maintenance cycle
  • For harsh environments, select full stainless steel flow passage and PTFE seal configuration
  • Ensure smooth exhaust pipe connection and clean working fluid to prevent damage
Applications
Widely used in petroleum, chemical, machinery, mining, light industry, papermaking, power, metallurgy, pharmaceutical, food industries, and municipal/agricultural sectors. Typical applications include vacuum filtration, vacuum feeding, vacuum degassing, vacuum evaporation, vacuum concentration, vacuum moisture regain, and vacuum packaging. Due to the isothermal gas compression process, it is especially suitable for pumping flammable and explosive gases; it can also pump dust-containing and water-containing gases, with a wide range of application scenarios.
2BV Series Vacuum Pump Applications in industrial settings
Frequently Asked Questions
Q1. Can I order a sample for performance testing?
Yes, sample orders are welcome. We can provide customized configurations (such as material, explosion-proof) according to your actual working conditions.
Q2. What materials are available for the pump's flow passage parts?
The standard configuration is cast iron with stainless steel impeller; optional full stainless steel flow passage parts for corrosive working conditions.
Q3. Is there a MOQ limit for this product?
No, the minimum order quantity is 1 unit, supporting sample procurement and small-batch orders.
Q4. What is the difference between explosion-proof and non-explosion-proof models?
Explosion-proof models (2BV2-Ex/2BV6 series) are equipped with dIIBT4 grade explosion-proof motors and IP55 protection grade, suitable for flammable and explosive environments; non-explosion-proof models are IP54, for general environments.
Q5. How to solve cavitation during operation?
The pump is equipped with a cavitation protection interface; connect it to a separator or open the interface directly when working under extreme pressure to eliminate cavitation noise and protect the pump.
Q6. What is the warranty period of the 2BV series water ring vacuum pump?
We provide a 1-year warranty, covering manufacturing defects and component failures (excluding wear parts and damage caused by improper use or harsh media without corresponding configuration).
Q7. How long is the delivery time for mass production?
8-12 working days after deposit confirmation; explosion-proof or customized material models may take 1-2 more working days.
Q8. How to choose the appropriate model?
Please provide parameters such as required pumping speed, vacuum degree, medium type (whether flammable, explosive, corrosive), working temperature, etc., and our technical team will recommend the suitable model for you.
Q9. Can the pump be used as a compressor?
Yes, when used as a compressor, the maximum discharge pressure is 0.26MPa (absolute pressure), suitable for low-pressure compression scenarios.
Q10. What is the service life of the mechanical seal and bearings?
Under normal working conditions, the mechanical seal service life is about 8000 hours, and the NTN/NSK bearings service life is about 15000 hours; regular maintenance can extend the service life.
