The new BDRY dry screw vacuum pumps are widely used in a variety of sectors worldwide.
Dry Vacuum Pump (Base 400 m3/hr) |
NEW BDRY Vacuum Pump (BDRY400) |
Competitor Vacuum Pump (430 m3/hr) |
Ultimate Pressure (torr)/50Hz |
0.0075 torr | 0.03 torr |
Motor Power | 11kw | 11kw |
Exhaust Gas Temperature | Below 120℃ | Below 150℃ |
Moisture and liquid processing capability |
Smooth emission structure (1) Superior liquid flowing ability |
Not Smooth emission structure The structure is not feasible to drain of liquid that is inappropriate for liquid processing. |
Condensation Vapor processing capability |
Installed Gas ballast (2) nozzle Prevent condensation of vapor by the gas ballast |
No Gas ballast nozzle installed Condensation occurs inside the pump. Condensed vapor or solvent are deposited inside pump and could cause overload trip. |
Corrosive vapor processing capability |
PTFE or PFA Coating application Prevent condensation of corrosive vapor by the gas ballast. By step-by-step compression, maintains low pump-inside temperature and protects coating. |
PTFE or PFA Coating applications Cumulated condensation of corrosive substances may cause frequent seal damage. |
Lubrication(Oil) Gear box side |
Gear Oil Coolant Jacket (3) Maintains low oil temperature Preventing oil leak and change of oil performance. |
No Gear Oil Coolant Jacket The oil temperature inside gear box shall be risen. It may makes oil leak and change of oil performance. |
Cooling gas (casing) |
No need No extra cooling gas required. Maintains low temperature by step-by-step compression. Hydrodynamic spiral jacket design ensures excellent heat exchange efficiency. |
Needed In hazardous areas Heat exchanger for cooling of circulation gas is required. Additional equipment and maintenance cost increases. In non-hazardous areas If the cooling gas filter clogged, the pumps is seizured. |
Note:
Smooth emission Structure:
Screw Vacuum Pump have an inherent disadvantage when it comes to draining and flushing.
The exhaust port is small and is not at the lowest point in the Vacuum Pump so liquid will not drain out of the Vacuum Pump.
But, the exhaust port of BDRY Vacuum Pump is big and is at the lowest point in the Vacuum Pump so liquid will drain out of the Vacuum Pump smoothly.
Gas ballast:
The basic principle of ballast is that Non-condensable gas (N2 or air) is admitted into a pump during the gas compression stages.
This increases the percentage of non-condensable gas such that the partial pressure of the vapor being pumped is below its saturated vapor pressure.
Gear Oil Coolant Jacket:
The lubricant oil in the gear box is cooled by a cooling water jacket.
