In addition, the PTFE grade is capable
of sustaining dry running conditions.
The seal fits within standard ISO/DIN
grooves. - Repack-S, Cuisery, France

This high-temperature sealant is
also available in sheets
This company's Therma-Pur ultrahigh-temperature
sealing material
(photo) is now available in sheet form
and in cut gaskets. Since its production
in 2011, the material has been field
proven to seal connections in biomass
gasification, marine and land-based
exhaust systems, turbochargers, mineral
and fertilizer processing, incineration
and cogeneration. The material is
available in 40  40 in. sheets with an
available fiber core thickness of 1/16
and 1/8 in. It is also available in precut
gaskets as well as in Kammprofile
and corrugated metal gaskets. The
proprietary material provides sealing
at temperatures of up to 1,000°C,
including extreme
thermal
cycling
conditions. Because
of its low
organic-fiber
content and nonoxidizing
formulation,
Therma-Pur exhibits
only minimal weight
loss at these extreme temperatures.

Save on maintenance and operating
costs with this elastomer
Kalrez perfluoroelastomer parts, such
as O-rings, gaskets, valve seats or diaphragms,
can withstand aggressive
chemicals and maintain tight seals
over a very wide temperature range.
In real-life applications, the seals have
been shown to save from 10 to 200% in
total system operating costs in chemical,
pharmaceutical and petrochemical
processes, says the company. Data
on file at the company showed that
seal lifetimes of O-rings in an aggressive
chemical process were about six
months for non-perfluoroelastomer
O-rings and about three years for Kalrez,
resulting in savings of 98% in cost
of O-ring seals, installation, downtime
and loss or productivity, says the
manufacturer. - DuPont Performance

fl uid competitor
No flow, remains completely
stuck in tube.
A world leader in industrial lubricants
Flows, but severe build-up of deposits
remains in tube.
CALFLO AF
Flows easily, stays cleaner longer.
CALFLO AF delivers longer fluid life and better equipment protection. And more savings to you.
We put CALFLO AF and leading competitors to the test in a challenging Severe Oxidative Stability Test and the results are clear. CALFLO AF
provides better oxidative stability for longer fluid life and enhanced equipment protection. That means more savings in operations
and maintenance costs. And less worry. Test CALFLO AF, or another product in our line of CALFLO heat transfer fluids, in your operation.
