DP-FE/D series

Categories: F 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

■ 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.
