DP-FsE series
DP-FE/D series
Corrosion-resistant Non-metallic Specification! Safe Design with Intrinsically Explosion-proof Specification.
A non-metallic model diaphragm pump that uses resin as the material even for the main parts, and employs a fiber-optic stroke sensor control model of the DP-Fs series.
Even if the one-piece diaphragm is damaged, metal ion contamination is prevented, and the pump can be operated with peace of mind in a corrosive environment, so it is suitable for CMP slurry transfer.
■ Main Applications
Transfer of Flammable Liquids in Explosion-proof Areas/Transfer of Chemicals, Pure Water, and Waste Liquids
Features
■ Seal Specification
| Hard Seal Supports expansion and contraction of the resin due to the heat cycle, and is resistant to temperature changes. |
|
■ Non-Metallic Specification
| One-piece Diaphragm Center disk less diaphragm with integrated center disk and diaphragm. Replacement is extremely simple, and it has excellent running costs. | Resin Center Rod By using resin as the center rod material, non-metal is achieved. |
|
|
■ Employs Fiber-optic Stroke Sensor Control.
Employs a fiber-optic stroke sensor control model that can be used even in explosion-proof areas.
◆ Sensor Control “Fiber-Optic Stroke Sensor”
| Non-metal, Explosion-proof Model By including a fiber-optic stroke sensor, the pump can be used in explosion-proof areas. |
|
| Sensor Control = Stable Reciprocating Motion A proximity sensor detects the stroke end of the diaphragm, and the pump controller receiving the sensor signal controls the switching of the center exhaust type 3-position 5-port solenoid valve. |
| Optional Counter Connection Enables Stroke Management By counting the number of times the center rod has moved, it is possible to determine when parts need to be replaced. |

*1 The pipe length from the air supply valve (solenoid valve, etc.) to the pump shall be 1.5 m or less. If piping from the exhaust port of the air supply valve to another location, the pipe length to the end of the exhaust port shall be 5 m or less.
*2 The compressed air quality shall satisfy quality classes both 2 and 3 specified in “JIS B8392-1:2000 Compressed air for general use.”
(Maximum particle diameter: 1 μm, Maximum open air pressure: －20°C, Maximum oil concentration: 0.1 mg/m3)
The maximum supply air pressure of a type with a resin-made pump body depends on the liquid temperature.
*3 The water discharge is provided as a rough approximation only. The discharge will differ depending on factors such as the liquid to be transferred and the piping conditions.
