Toots type / Display by Actual Pumping Speed / With protective functions
Features
Small type of roots type vacuum pump.
In the pressure area where the pumping speed of Sub pump decreases, the pumping speed can be greatly increased.
- By adopting a DC brushless motor, it can be operated at an optimum rotational speed according to the load, so vacuum exhaust from atmospheric pressure is possible.
- No oil leakage to the outside of the pump due to the magnetic coupling structure.
- The pump's internal seal uses a non-contact seal, which significantly reduces mechanical loss.
(Power consumption is reduced by about 60% compared to the old model) - It is possible to operate with 100V system and 200V system by switching power supply inside the driver box.

Caution
|
１
|
Cannot use mechanical booster vacuum pump with a unit, and combine it with a backing vacuum pump (Fore Pump) by all means.
|
|
２
|
Mechanical Booster Pump becomes design to use in an inline.
Fix flange of the outlet side, and install a pump in this flange. |
|
３
|
Since pump oil bubbles at the time of starting when not operating initial operation and for a long period of time, please perform the exhaust gas for degassing with a backing vacuum pump.
|
|
４
|
Since operation in the atmospheric pressure neighborhood becomes the same grade as the exhaust speed of a backing vacuum pump, the feature of a booster is not demonstrated.
|
|
５
|
If pump oil exceeds the amount of regulations, oil will go into a rotor indoor part.
|
|
６
|
Please be sure to check that power supply voltage has agreed with the setting voltage of a pump.
|
|
７
|
The base for pump installations is not equipped. It becomes flange fixation.
|
|
８
|
The handle for pump carrying is not equipped.
|
|
