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:
(1) 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.
(2) 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.
(3) Gear Oil Coolant Jacket: The lubricant oil in the gear box is cooled by a cooling water jacket.
