*1. Maximum air pressure for non-metallic pumps decreases with temperature (See 21 page of Temperature
Pressure Curve).
*2. Discharge Volume/cycle is highly dependent on application. Contact your local distributor or Yamada for
more information.
*3. Do not use the flat valve type pump for the liquids with slurry.
*4. The measuring method is based on ISO 1996.
*5. The measuring method is based on ISO 3774.
