FUTUR Air-Operated Double Diaphragm Pumps (AODD) by Almatec
Designed for chemical supply and circulation for the semiconductor industry
Since 1984 ALMATEC manufactures special pumps for the chemical supply and circulation in the semiconductor industry. The FUTUR series is particularly developed for the special requirements of these applications.
The liquids handled in the semiconductor industry set different demands to the pumps. Therefore the FUTUR series is available in four materials:
- 4 sizes made of PTFE/UPPE for acids and caustics up to 130°C/266°F (model FUTUR T)
- 2 sizes made of PTFE for hot applications with acids and caustics up to 200°C/390°F (model FUTUR H)
- 4 sizes made of UPPE for slurries (model FUTUR E)
- 2 sizes made of stainless steel (SS 316 L) for solvents (model SLS)
The different pump sizes achieve max. capacities between 10 and 200 l/min (2.6 - 52 gpm). For every pump size and material are appropriate pulsation dampers available.
All FUTUR pumps are self-priming pneumatic diaphragm pumps which may run dry. The pumps have a compact, simple design with few parts only. The housing parts are machined from solid blocks, the basis for a long life time. FUTUR pumps are cleaned, assembled, and tested in a class 100 clean-room line.
The latest generation of the FUTUR pumps is the FUTUR-Omega series:
- entirely made of PTFE
- new construction with Ω-shaped base frame
- diaphragm and center housing with rotation prevention
- new PTFE material for the diaphragms
- three sizes with max. capacities of 20, 50 and 100 l/min (5.3, 13, 26 gpm)
- depending on the application also available entirely made of polyethylene and SS316L
Applications for FUTUR Pump
FUTUR T When delivering acids and caustics, corrosion resistance is of the highest importance, so the center housing is constructed of special PTFE-TFM. Compared to normal PTFE, it has a higher tensile strength and surface density. Parts made of this material are smooth and free of pores, which results in reduced particle generation. The pumps are absolutely metal-free and can be used in temperature ranging up to 130°C (266°F).
• High purity chemicals
FUTUR E The FUTUR E model has been designed to be abrasion-resistant, which is a requirement for pumping slurries. To meet these operational demands, they are constructed of PE (polyethylene). It has a very high abrasion resistance (higher than steel), good impact value and withstands the introduction of slurry particles. Its good chemical properties allow handling both basic and acidic slurries. The FUTUR E is metal-free, with a maximum permitted liquid temperature of 70°C (158°F).
• Basic slurries
• Acidic slurries
FUTUR H FUTUR H model pumps have been designed to operate ideally in hot applications involving acids and caustics. The temperature limit is 200°C (390°F) at max. 2 bar (29 psig).
• Hot applications with acids
• Hot applications with caustics
FUTUR SLS model pumps feature stainless-steel (316L, with extremely low carbon content) construction, making them ideal for handling solvents, mixtures of solvents and strippers. The housing parts are machined from a solid block of rolled steel and polished afterwards, the only way in which a pore-free surface can be secured. The pumps can be used in temperature ranges up to 130°C (266°F).
• Solvent mixtures
