Diaphragm Seal - 1

4, Gilchrist Road, Northbank Industrial Park, Irlam, Manchester, UK. M44 5AY.| Made in Britain ' Email: sales@budenberg.co.uk Web: www.budenberg.co.uk A Diaphragm or 'Chemical Seal' is a mechanical barrier that protects delicate instruments from harsh process fluids such as strong Acids, Alkalis and Slurries. All Chemical Seal units operate in an identical manner: the process medium acts upon a diaphragm the deflection of which is transmitted via the fill medium. This pressure is then displayed or transmitted. The style and materials of construction are carefully selected to withstand not only the process medium but also the maximum design pressure and temperature for each application. For the sake of this overview, we have concentrated on the use of pressure gauges but 'Budenberg' chemical seal assemblies can be used with pressure transmitters, transducers

Diaphragm Seal - 2

Model 254 and 255 A flexible range of diaphragm seal Gauges with features for use in an extensive variety of applications throughout industry to include the most arduous process situations Filling Fluid Syltherm is our standard filling fluid. This is suitable for temperatures from -40 ̊ C to 200 ̊ C. Silicone Oil (STD) is available for temperatures from -40 ̊C to 200 ̊C. Silicone Oil (HT) is suitable for temperatures from 0 ̊ C to 300 C. ̊ Glycerine or glycerine/water mixtures or medicinal paraffin are suitable when the gauges are to be used for food and drink manufacturing or processing....

Connection Types - Clamped versions Budenberg manufacture a number of connection options and we are renowned for the quality of our seal assemblies - modified for critical applications. Our 'Field Serviceable' chemical seals provide the option for removal and cleaning of wetted parts and also for the replacement of diaphragms which, in the long term will radically reduce operating costs: it is far more cost effective to replace a diaphragm than a whole assembly whether connected to a gauge, transmitter or switch. Clean-out Six holes for 8mm bolts on 83.5 PDC Screwed External Hygienic To...

Diaphragm Seal - 5

Hygienic Diaphragm Seal Gauges Ultra-safe diaphragm seal gauges For diary, brewing, pharmaceutical and food industries For toxic service The illustration shows a pressure gauge similar to the 254 described in this broad form. It incorporates certain safety features, however, that significantly reduce the risk of the process media escaping to atmosphere. Our specialised gauges - with these features - are used to measure the pressure of highly toxic materials e.g. liquid chlorine and vinyl chloride, both of which can kill or seriously harm plant operatives at very small levels of exposure....
