DP-FE/D 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. 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.
A fiber-optic stroke sensor is employed, enabling use in explosion-proof areas.
Explosion-proof, standard seal specification. The flat valve type is optional (built-to-order). Contact us for more details.
■ Main Applications
Transfer of Flammable Liquids in Explosion-proof Areas/Transfer of Chemicals, Pure Water, and Waste Liquids
Features
■ Seal Specification
| Standard Seal A PVC seal that absorbs changes in the dimensions of the join section for the fluorine resin pump. |
|
■ 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.
*4 The maximum flow rate is based on test data using a Φ8 x Φ6 x 2.5 m connection air tube, 0.5 MPa of supply air pressure, purified water, head 0, and at room temperature. However, the DP-25FE and DP-38FE are based on test data using a Φ12 x Φ10 x 2.5 m connection air tube and 0.7 MPa of supply air pressure.
*5 The flat valve type cannot handle slurry. • In the case of standalone pump sales for the DP-FE/D series, only a 5.0 m sensor cable is included, and the pump controller (MFC-24), solenoid valve, etc. are sold separately.
