※1：The DP-5F valve is a flat (plate) type.
※2：Since a DP-25F and a DP-38F are to be produced on orders, be sure to check the delivery date.
※3：The suction inlet or discharge outlet of a DP-10F/20F pump can be connected with an NPT screw orANSI flange (custom-designed) as well as a standard RC screw or flange.
※4：The maximum discharged liquid amount and/or self-suction capability are based on the test datameasured with using fresh water at the room temperature (20oC). In addition, the amount of dis-charged liquid varies depending on the supplied air pressure or pump head. Please check the per-formance curve for details.
※5：Use the clean air that has passed through a 1-μm filter or nitrogen gas (N2) as air to be supplied tothe pump.
＊When you use a resin pump, it may not offer the designed performance due to significant change oftemperature. To maintain its performance, be careful to install the pump or store its parts.
＊Any flat valve type of pumps cannot handle slurry.
