CRANE ChemPharma, Saunders Life Science elastomer
diaphragms offer superior sealing capability and low costs.
Properly selected and applied elastomer diaphragms can
handle a wide range of process media typical of bio-pharm
applications. CRANE ChemPharma, Saunders proprietary
compoundsoffer industry leading levelsofperformance.
Ethylene propylene (EP) based elastomer is the most
commonly used diaphragmmaterial in the Pharmaceutical
industry. This material offers excellent physical properties,
including chemical compatibility (ionic fluids), thermal
resistance, and physical strength. CRANE ChemPharma,
Saunders EPM diaphragms offer enhanced performance for
the demanding application criteria found in the bio-pharm
environment.

TypeEEGradeEPDMDiaphragms
The EE grade diaphragm is constructed from Ethylene
propylene diene (EPDM) base polymer. Originally developed
tomeetbio-pharmcustomer requirements foranEPDMgrade,
this diaphragm has demonstrated excellent performance
on the full range of bio-process applications. The EE grade
diaphragmhas full industry compliance. Availablepost cured
variationdesignatedasgradeE5.
Type500GradeSiliconeDiaphragms
The 500 grade diaphragm uses a dicumyl cured silicone that
is fabric reinforced to optimize flex life. This is awhite grade
of diaphragmwhichoffers very low levels of extractables and
leachables. Silicone is ideal for low temperatureenvironments
and applications. Like all Life Science Diaphragms, the 500
gradeSiliconeDiaphragm isFDAconformingandUSPClassVI
testedandcertified.
