Since federal, state and regional environmental regulations on fugitive emissions were first introduced beginning in the early 1990s, manufacturers of pharmaceutical products have been refining their processes to improve the performance of their rotating equipment and remain within compliance with local and federal regulations. Lower emissions and improved purity of end products are the two main focuses with sealing rotating equipment, along with being a good community neighbor for the pharmaceutical industry.

Flowserve FSD has close relationships with many of the end users and specialty equipment manufacturers and knows the industry requirements:

• No product contamination allowed
• Low or no emissions to atmosphere
• A wide range of materials of construction including ‘food grade’
• Low leakage rates
• Electro-polish finishes available on critical metal surfaces for ease of cleaning and increased sanitary protection
• Sanitary glands and debris wells.
• Application experience sealing high alloy vessels as well as glass lined vessels
• A long history of experience sealing top entry, side entry and bottom entry mixer and agitator equipment with great success
• Application parameters have been met from very low speeds to very high speeds with gas seal designs and from cryogenic vacuums to very high pressure and high temperature autoclaves with dual seals
• Seals are designed for Clean In Place (CIP) and Steam In Place (SIP) applications as well as the ability to stand up to caustics and acid between batch flushes
