DP-FsE series

■ 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.
