MBF diaphragms have been developed specifically for Bio Pharmaceutical applications and are highly reliable, clean and offer excellent performance. We perform extensive research and continued development on the materials to ensure that quality is maintained and improved. All the diaphragms are manufactured with complete traceability of material and processes meeting ISO 9001-2000 requirements.

PEROXIDE CURED EPDM CERTIFICATION & APPROVALS
MBF EPDM compound is fully compliant with FDA CFR Section (21) 177.2600 and has been fully tested and certified in accordance with U.S. Pharmacopoeia Class VI Section (87) in-vitro and Section (88) in-vivo biological reactivity tests by the accredited NAMSA.

EPDM EXTRACTABLES AND PRODUCTION
EPDM compound has been developed and independently tested to have the lowest percentage of extractables, significantly less than similar competitive commercial compounds. MBF EPDM compound
is produced in just-in-time batches to meet tight diaphragm production and is stored for very short periods of time to ensure greater reliability of the mechanical properties of the diaphragm after production.

TFM PRODUCTION
MBF TFM diaphragms are manufactured utilizing a unique high pressure molding technique that ensures a higher uniform density that is virtually non-permeable. This process significantly increases the cycle life of the diaphragm under harsh conditions.

TRACEABILITY
All MBF diaphragms are fully traceable to a specific batch of molded compound. Test certificates and compound properties for each specific batch are recorded and maintained within the QA System.
Diaphragms are physically identified with the date of manufacture and the compound identification code.

Each MBF diaphragm valve is supplied with your choice of elastomer or TFM/elastomer backed materials. Our diaphragms are completely compliant with the most recent FDA Codes and USP Standards.

Elastomeric diaphragms are molded in the open position, while TFM faced diaphragms are molded in the closed position. All elastomeric diaphragms are attached to the compressor via threaded stud.

MBF TFM faced diaphragms are attached by a bayonet type fixture that eliminates point loading. This provides constant diaphragm compression across the weir resulting in a uniform, reliable seal. Optional TFM faced diaphragms can be supplied with a thread type fixture for interchangeability with other manufacturers.
