Air Cooled Screw Vacuum Pump and Roots Vacuum Pump for Drying Dehydration

 Product DescriptionDry screw vacuum pump, is the use of a pair of screw, made in the pump shell synchronous high-speed reverse rotation of the effects of the suction and exhaust and suction device, two screw fine dynamic balancing correction, and is supported by bearings, is installed in the pump shell, between screw and screw has a certain gap, so the pump work, no friction between each other, smooth running, low noise, Working chamber without lubricating oil, therefore, dry screw pump can remove a lot of steam and a small amount of dust gas occasions, higher limit vacuum, lower power consumption, energy saving, maintenance-free and other advantages.Dry Oil-Free Air Cooling Screw Vacuum Pump ,This is an advanced and widely used vacuum pump at present, It is one of the best-selling products of our company. It adopts explosion-proof motor with high configuration, It has the characteristics of low noise, no oil and pollution, clean and high vacuum, simple and convenient use, operation and maintenance, Widely used in many industries, For example, oil and gas recovery, vacuum coating, biomedicine, food processing, single crystal furnace, vacuum forming, vacuum melting, electronic photovoltaic, semiconductor synthesis and many other industries are used.The dry oil-free screw vacuum pump produced by our company is divided into air cooling and water cooling according to the extraction rate, and there are many models for you to choose.Our AdvantagesThere is no medium in the working chamber, which can obtain a clean vacuum.. No clearance between rotating parts, high speed operation, small overall volume.There is no compression in the gas, suitable for extraction of coagulable gas.Can remove a lot of steam and a small amount of dust gas occasions.. High vacuum, the ultimate vacuum up to 1 Pa.Screw material is high strength special material, material density, wear resistance, stable performance.No friction rotating parts, low noise.. Simple structure, convenient maintenance.Wider range of use: corrosive environment can be used.No oil consumption, no water.Pump gas directly discharged from the pump body, no pollution of water, no environmental pressure, more convenient gas recovery.It can be composed of oil-free unit with Roots pump and molecular pump. Typical Use------Oil and gas recovery.    ------Biological medicine ------Food Processing ------ Single crystal furnace------Vacuum forming ------Vacuum flame refining ------Electronic photovoltaic. ------Semiconductor synthesisProduct Parameters Air cooling   Dry screw vacuum pumpType(Air cooled series) Basic parameters Pumping speed(m3/h)Presure limit(Pa) Power (kW) revolution (rpm)Inlet caliber(mm)outlet caliber (mm)Pump head weight(kg)noise dB(A)Overall dimension(length*width*height)(mm)LG-1010≤50.752730KF16KF1630≤ 72655x260x285LG-2020≤51.12840KF25KF2555≤72720x305x370LG-5050≤102.22850KF40KF4090≤75920x350x420LG-7070≤3032850KF40KF40110≤75910x390x460LG-9090≤3042870KF50KF50125≤801000x410x495Water cooling Dry screw vacuum pump  Type                                                                            Basic parametersPumping speedm3/hPresure limit(Pa) Power (kW) revolution (rpm)Inlet calibermmoutlet caliber mmCooling water volumeL/minnoise dB(A)Overall dimension(length*width*height)mmLGV-18018054290040402< 781157x375x734LGV-25025055.5290050405.5
