Extension of the standard field of application through special Elastomers The standart field of application of the elastomer bellows mechanical seal over the household engineering, water engineering as well as sewage engineering and fields, where the chemical resistance is sufficient. Through development of special elastomers in the laboratories of Hecker Werke, the bellows and the cup-rubber or o-rings of the stationary seats can be produced in HNBR, EPDM and FPM, all with FDA permission. In combination with the standard face materials with FDA permission, the application in drinking water and other liquids in food industry is possible. |
