A stainless steel, air-operated diaphragm pump for transferring pure solvents in the semiconductor industry has been released by Almatec.
Part of PSG, a Dover company, Almatec has just announced that its Futur S and SH pump series are now available in 316 stainless steel with a high surface finish.
Key features of the S/SH Series pumps for pure solvent transferring
The Futur S/SH series air-operated double diaphragm (AODD) pumps incorporate what Almatec dubs a ‘straight-through flow pattern’, with only one wetted housing part (the centre housing). The air control system and air chambers are located in the side housings.
According to a statement from Almatec, the design ensures that only one part of the housing comes into contact with the liquid, reducing the number of flow bends, minimising the surface area, eliminating sliding parts in the product chambers and making it possible to eliminate gaskets.
The AODD pumps are self-priming with dry run capabilities, and come equipped with the PERSWING P Air Control System to optimise air consumption and production rates.
What you need to know
The pumps are available in two pump sizes: 20 and 50 lpm (5.3 and 13 gpm). Both feature diaphragms and valve bodies made of solid PTFE without inner elastomer or metal parts that increase the risk of contamination. Wetted seals are also available in solid PTFE.
The non-wetted side housings on the Futur S Series pump are constructed of PE conductive material and can be used for temperatures up to 80°C (176°F). The side housings on the Future SH series pump are constructed of 316 stainless steel for temperatures up to 130°C (266°F).
