Oil Rotary Vacuum Pump

GHD Series

GHD-101A

アルバック

Two-stage / with cord, and switch/with thermal protector

Features

  • Small size but high exhaust speed.
  • Compact size suitable for device integration.
  • The magnet coupling structure eliminates oil leakage from the shaft seal and achieves long life.
  • There is no oil contamination in the vacuum chamber due to the installation of the check valve directly below the intake pipe.
  • Corresponds to diversification of power cord by power cord inlet and outlet.
  • The exhaust speed is stable due to the installation of the forced oil supply mechanism.
  • Operation from atmospheric pressure is possible.
  • Easy connection with flanged parts and connection by knock pins on internal parts.

Caution

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.
If operation is performed at high pressure, oil mist is generated at the exhaust side.
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.
This motor houses an automatic returning thermal protector, which may be activated in case of trouble.
The motor will restart automatically when the temperature goes down.
If the thermal protector is activated, switch off the power immediately for safety reason.
