Remarks

  • The pump is stopped when the lord is operated, and the pump can’t be operated just after that. In this case, please return the atmospheric pressure the inside of the pump.
  • The pump will not often operate normally if it is used with corrosive gases, organic solvents, liquids, or condensed gases (eg steam). The pump will not often operate normally if it is used with gases containing particles or dust etc.
  • Cup packing that is the sliding material of the pump will be worn out by operating, and microscopic particles result from wear of component. Moreover, wear is promoted because the sliding material is weak in moisture, and the pump life decreases if the vacuum gas is moisture. Please suck neither moisture nor condensed gas (steam etc.).
  • It is a pump only in the room. Please do not set it up in the place, that rain and water splash, and outdoors.
