Liquid ring vacuum pump design features
2bva series liquid ring vacuum pump is a single-stage pump with integral structure and one pump coaxial. The shaft seal adopts mechanical seal, which has the characteristics of simple structure, simple installation, oil-free, safe and reliable. This series of vacuum pumps is suitable for pumping atmospheric and moist steam. The minimum suction pressure can reach 33mbar (3300pa), which is better than SK and 2SK series pumps in terms of technical performance (similar to pumping speed).
