Oil Rotary Vacuum Pump
GLD・GLS Series
GLD-137AA
アルバック
2-stage exhaust system / with backflow prevention function / with gas ballast mechanism / input terminal (without cord)
Features
- The two-stage exhaust system has lower pressure (good vacuum) than the one-stage exhaust system.
- Low noise and low vibration.
- The backflow prevention mechanism prevents oil from flowing back to the vacuum chamber when it is stopped due to a power failure.
- The exhaust speed is stable due to the installation of the forced oil supply mechanism.
- Operation from atmospheric pressure is possible.
- Easy connection by internal components knock pins and maintenance by flange motor.

※1：Ultimate pressure is measured by Pirani gauge.
(In the case of measurement by McLeod gauge, the value is lower by an order of magnitude for pumps with an Ultimate pressure of 1.3 Pa or less.)
※2：Power supply plug and Power supply code are not included.

Caution
|
１
|
Oil is deteriorated with operating, and becomes the factor of performance shortage.
A decrease and the dirt of oil are confirmed, and please regularly add and replace it. |
|
２
|
The backflow prevention valve mechanism prevents the pump oil backflow to the vacuum tank side at the time of emergency such as power failure.
Please make a suction side into atmospheric pressure when the pump is stopped for a long time. |
|
３
|
If operation is performed at high pressure, oil mist is generated at the exhaust side.
|
|
４
|
There is no built-in motor protection function.
Protect the motor with a motor breaker. |
|
５
|
It is not suitable for the pump if operation is performed continuously at a high evacuation pressure of 10kPa or more.
|
|
６
|
There is a risk of explosion. Never block the outlet or operate the pump with equipment mounted at the outlet side that blocks the passage of gas.
Otherwise, the internal pump pressure increases causing the pump to explode, the oil level gauge to protrude or the motor to be overloaded. |
