● inhalation efficiency (up 15%).

● improved exhaust efficiency (2 levels of variable, continuously variable frequency).

● ultimate pressure: 1*10-2 torr (torr).

● the exhaust temperature is reduced by 50%.

● power consumption is reduced by 30%.

● do not use oil and water, and will not cause oil and water pollution.

●low power consumption, low noise, low vibration, good dynamic balance, no inertia, high speed operation.

● directly connected design, easy to install and easy to maintain.

● anti-wear and corrosion resistance.

● all imported mechanical seals are used as standard.

● anti-cavitation, low maintenance.

●all use y2 series motors, protection grade ip54, ip55 (commonly ip44), insulation grade f grade insulation (commonly grade b insulation).

●all use ntn or nsk imported bearings.

● 2bv series water ring vacuum pump can realize flexible seals all of ptfe, which can greatly extend the service life of vacuum pumps under severe conditions.

●the ultimate pressure can reach 2kpa, and the inlet working pressure range is 5kpa-20kpa.

●200-7500m3/h various specifications to meet various process needs

●selected materials such as stainless steel, duplex steel, titanium, hastelloy

●reliable impeller locking and anti-loose mode

● mechanical seal at both ends, multiple flushing options

● standard anti-cavitation device

●reliable performance, high efficiency and energy saving

● synchronous gears are easier to ensure synchronization, ensuring quiet and reliable operation. the synchronous gear is installed on the non-drive end to ensure smooth running of the pump;

●two-blade roots rotor: the impeller is integrally cast with the shaft to provide a large-sized shaft and reduce the risk of impeller damage;

●the interior of the rotor and the cavity are coated with hastelloy, which is suitable for corrosive substances in the pumped medium;

●all surfaces of the shaft in contact with the seal are polished to reduce seal wear and reduce the risk of leakage;

● environmental assessment is passed. the dry screw vacuum pump is adopted, and the recovered material has high purity, and can be 100% recycled without pollution, and no sewage treatment is needed in the later stage;

● save energy. compared with energy saving of 40% or more, water saving is over 90%.

●high vacuum. the ultimate vacuum of the water ring roots unit is 200pa and the ultimate vacuum of the screw roots unit can reach 1pa, which greatly shortens the reaction time;

● greatly improve product quality and purity. the water content of the product can be reduced from the original 0.4% to the current 0.0012%;
