Sealless pumps continue to perform admirably Thanks to their proven record of in creased safety, reduced emissions, and longer maintenance intervals, sealless canned-motor and magnetic-drive pumps continue to replace traditional pumps fitted with mechanical seals And their capabilities continue to grow.

More doors open for thermoplastic elastomers Having already satisfied many mar kets, thermoplastic elastomers (which combine a soft elastomeric phase and a hard rigid phase) are promising to displace their traditional counterparts in other applications thanks to their versatile chemical and physical attributes.

Engineering Practice: Use this spreadsheet to calculate critical flows Expanding gas flow can lead to abnormal flowrates and excessive pressure drop. Flowrate calculations have to account for adiabatic expansion and frictional losses at high velocities. This article discusses an Excel spreadsheet (which can be downloaded for free) that addresses expanding flow conditions, and calculates flowrates.
