1. Outline of Equipment
1-1. Intended Use and Prohibitions of Equipment
This diaphragm type dry vacuum pump performs evacuation by reciprocating motion of rubber
membrane (diaphragm).
PTFE (corrosion resistance resin) used for parts exposing to gas obtained superior corrosion
resistance.
Please take note of the following prohibitions to use Equipment correctly.
<Prohibitions>
(1) This pump is for evacuation only. Never use for pressurization.
(2) Do not do resale, repair, and remodeling that we agreed on.
(3) Although this pump is designed for corrosion resistance specifications,
corrosion resistance may not be shown exceptionally for strong acid (for
example: metallic sodium), fluorine under a high temperature, and
certain fluorine compound due to erosive action.
(4) Although corrosion resistance resin for external packaging of DTU-20
partly, there are chemicals that erode the corrosion resistance. Prevent
splashing the following chemicals on the pump. It is recommended to
wipe off chemicals attached regardless description in the followings.
Acetone · Ethyl ether · Ethyl acetate · Flora and fauna oil, etc.
(5) Never absorb the gas that mixed dust, dust, moisture (except steam).
(6) Do not operate long time in environment near the atmospheric pressure.
