Single or Multistage Stage Variable Pitch Air Cooled Oilless Oil Free Electrical Dry Rotary Screw Vane Vacuum Pump For Vacuum Industry

DS Series Dry Screw Vacuum Pump Features1.Exhaust Path Is Short, Reduce The Deposition Of Reactants.Comparing with other types of dry vacuum pump,DENAIR screw vacuum pump has the shortest gas path in the vacuum pump and that could reduce the contamination of process gas. Screw rotors can play as a powder transmission mechanism,we runs well even there has lots of contamination inside the pump.2.The Optimal Linear Sealing, The Pump Performance.Patented rotor profile can provide rotor excellent sealing effects thus a larger clearance is allowable in between.Pump rotor wesring and rotor jam by the process contamination can be reduced by larger allowable clearcance.3.Simple Structure, Low Fault Rate And Easy MaintenanceScrew type vacuum is composed by a pair of screw rotor and isolation plates are required in different between rotors and isolation plates can also be avoided.Overhaul Hanbell dry pump is much easier than other type of dry pump,so the erpair time is shorter and the cost is saver.4.Microcomputer Operation, Remote Monitoring, Considerate ProtectionMicroprocessor controller provides lots of pump parameters for running status monitoring.Pump can be easily operated and monitored by the operation panel.Remote control software can help the customer monitor the pump running status remotely.DS Vacuum Pump Speed CurveAdvantages1.Special cooling liquid cooling, to avoid the cooling water may cause corrosion to the hull. 2.Mobile operation interface, convenient operation; Display and the actual work of vacuum pump and can be selected to both languages, according to the real close to the customer.3.Catch the power connector, safe and convenient.4.The nitrogen gas heater, make the vacuum pump is more suitable for CVD, PECVD and other semiconductor technique process.5.The control signals and communication signal interface, remote monitoring was carried out on the vacuum. Application1.The health care industry.2.Lighting industry.3.A variety of analytical instruments.4.Electronics, semiconductor industry. 5.The power industry.6.Refrigeration industry.Technical PrametersTypeUnitDS180DS250DS360DS540DS72050Hz60Hz50Hz60Hz50Hz60Hz50Hz60Hz50Hz60HzPumping speedm3/hr180216250300360432540650720850L/min3000360042005000660079209000108001200014400L/S50607084110132150180200240Extreme pressurembar0.020.010.020.010.020.010.020.010.020.01Torr0.0150.00750.0150.00750.0150.00750.0150.00750.0150.0075Pa2121212121PowerkW7.57.57.57.5111518.518.52222SpeedRPM2900355029003550290035502900355029003550Inlet diametermm6580100150150Outlet diametermm4040656565Gear chamber oil contentL0.850.85 1.40 2.00 2.00 Cooling waterL/min2.50 2.60 2.80 3.00 4.00 gal/min0.67 0.70 0.75 0.80 1.07 WeightKg295350480520680Noise leveldB(A)7578818586Room tempºC5-40Maximum permissible humidity90% TypeUnitDSV250DSV360DSV540DSV720DSV120050Hz60Hz50Hz60Hz50Hz60Hz50Hz60Hz50Hz60HzPumping speedm3/hr25030040048058070080096012001440L/min420050006600792096001150013200158001980023700L/S7084110132160192220264330396Extreme pressurembar0.020.010.020.010.020.010.020.010.020.01Torr0.0150.00750.0150.00750.0150.00750.0150.00750.0150.0075Pa2121212121PowerkW5.57.57.51111151518.52222SpeedRPM2900355029003550290035502900355029003550Inlet diametermm6580100150150Outlet diametermm4040656565Gear chamber oil contentL0.850.851.422Cooling waterL/min2.50 2.50 2.60 2.80 3.50 gal/min0.67 0.67 0.70 0.75 0.94 WeightKg295350480520680Noise leveldB(A)7273757880Room tempºC5-40Maximum permissible humidity90%Note:1.The amount of oil listed above is for reference only and is usually fluoride and mineral oil.
