Oil-Sealed Rotary Vacuum Pumps

G Series

G-101D

Outline

This is a rotary blade type vacuum pump that uses lubricating oil. A vacuum pump with low noise, low vibration and high reliability. G series is a standard type.

Features and Cautions on use

  • The oil rotary vacuum pump which had abundant track records and realized budget prices.
  • The vacuum pump in which it is small and carrying is useful.
  • Compact size suitable for equipment inclusion.
  • The motor direct connection type with which a high velocity revolution and a small and big exhaust speed are obtained compared with a belt system.
  • Low vibration and noise.
  • A two-stage exhaust system is pressure (good vacuum) lower than an one-stage exhaust system.
  • The safety design by manual return type thermal protector built-in.

Remarks

  • 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.
  • Please make a suction side into atmospheric pressure when the pump is stopped. If it holds with a vacuum state, pump oil will be full in a pump room, and pump oil will flow backwards to the vacuum-chamber side.
  • 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.
  • It is a pump only in the room. Please do not set it up in the place, that rain and water splash, and outdoors.
