DP-Fs series
Corrosion-resistant Non-metallic Specification!
F series with Consideration to the Environment Where the Pump is Installed. 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. The air switch valve employs the non-metallic specification PEEK spool. Equipped by default with a hard seal that is resistant to temperature changes, and prevents liquid leakage, giving peace of mind.
■ 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 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 Non-Metallic Specification PEEK Spool
The air switch valve employs a non-metallic specification PEEK spool.
◆ Air Switch Valve “PEEK Spool”
| PEEK Resin Is Employed for the Spool Valve and Engineering Plastic Is Employed for the C-spring. This prevents operation failure due to rusting of the spool, or metal ion contamination that arises from transfer liquid penetrating the switch mechanism due to diaphragm damage. |

*1 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.
*2 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.
