Performance Characteristics
Clean vacuum
Oil-free and zero pollution inside working chamber; High recovery rate of the process gas; Easy treatment of the tail gas, which can reduce the safety risk and operation cost;
Cooling efficiency
Stable operation can be achieved by using jacket cooling and using a small amount of cooling circulating water;
Using condition
It is suitable to extract condensable, corrosive, flammable and explosive, easy to crystallize, easy to solidify and other gases, and is also suitable for various harsh working conditions;
Stable and reliable
The unique multi-stage helical rotor eliminates the middle baffle structure, and there is no intermediate stage suction and exhaust process. The working process is simple, continuous and high efficiency;
Easy to maintain
The rotor has no contact, no wear, simple structure, few parts, easy maintenance, and long life of the whole machine.
Adaptable
The intake pressure can work from 1Pa to atmospheric pressure. It can be combined with Roots pump, molecular pump, etc., and can be used as a backing pump with high pumping efficiency.
Equal Pitch Screw
·National patent (ZL 201921451548.2);
·High rough pumping efficiency, and it can operate stably in rough
vacuum conditions, which greatly expanding the working pressure range;
·No internal compression and high pump temperature, which is suitable
for gas that is easy to condense and crystallize at pumping speed;
·The rotor gap is large, and solid dust and condensate are not easily
deposited between the rotors and chamber.
Variable Pitch Screw
·National patent (ZL 201921451576.4);
·Small gas reflux, low power consumption and more energy-saving;
·Low discharge and working temperature, which is suitable for removing flammable, explosive and coking gases;
·Low gas recoiled by the exhaust gas, which radically reduces the operating temperature and noise of the pump.
·Optional 1: Nitrogen blowing system
·Optional 2: Discharge muffler system
·Optional 3: Auto clean solvent system
·Optional 4: Inlet filtration system
·Optional 5: Discharge reservoir system
·Optional 6: Water inlet control system
