High Performance SM? Filter
Cartridges
CKC manufactures SM? Filter Cartridges under technical licensed and filter
media supply by Martin Kurz & Co.,Inc.
SM? filters were developed to replace poorly
performing sintered porous metal, wedge-wire, string wound and other types of
cartridges. In many instances, flow rates may be dramatically improved without
compromising filtration efficiency. In other instances, frequency of downtime
for element cleaning and replacement may be sharply reduced, resulting in
savings which can far outweigh initial retrofit costs.
Standard Cartridges Design
Standard SM? filters are 2-1/2" OD non-pleated
cylinders with one longitudinal weld seam, and welded end-fittings. Elements
longer than 36" nominal are constructed in segments with machined joiner rings.
SM? filters are available in two styles: Gasket-Seal Series and Threaded
Connector Series.
Operating Parameters
Given their 100% 316L stainless steel construction,
standard SM? elements are appropriate to any environment compatible with this
excellent alloy. Recommended temperature: up to 600?? F for threaded connector
elements. Gasket-seal elements are limited by the temperature resistance of the
gaskets as follows: Buna-N 300?? F, Viton 400?? F, Teflon 450?? F. Recommended
maximum pressure differentials: 100 psid forward flow (outside-to-inside), 50
psid reverse flow.

Quality
Construction
Standard SM? cartridges are
constructed in 100% extra low-carbon stainless steel, including SM? filter
medium hardware, and welding filler materials, affording absolutely maximum
corrosion resistance. End fittings are CKC-designed heavy gauge custom-machined
hardware, combining retrofit compatibility, ease of use, and maximum structural
strength. Our high-quality welds are 100% leak-tested during assembly to insure
structural integrity.
Unique SM? Filter
Medium
Drawing on decades of experience
in the field of sintered metallic filter media, CKC has developed optimized
filter medium constructions which are produced by our unique laminating,
sintering and HIP diffusion-bonding processes. These processes have been refined
to provide maximum physical integrity with no metallurgical degradation or loss
of corrosion resistance. SM? filter medium is specifically designed for
high-performance cylindrical cartridge architecture, and provides optimal
surface collection and barrier filtration of particulate contaminant. |
Cleanability
SM? elements are fully cleanable
and reusable, eliminating repeated cartridge replacement and waste cartridge
disposal. A variety of cleaning methods may be employed, including chemical
processing and high-temperature hydrogen furnace heat treating. CKC can advise
cleaning methods, offer reconditioning services, or recommend outside
contractors who specialize in the cleaning and testing of stainless steel filter
elements.
Wide Performance
Range
SM? is available in nine standard
filtration grades, ranging from 100 down to 2 microns nominal (98% removal
rating for liquid filtrates), with total weight removal up to 99.99% under
optimal conditions. With availability in standard all-316L stainless steel, or
alternate materials for special applications, compatibility with high flow
rates, high temperatures, high pressures, precoats, and corrosive environments,
SM? filters can meet the demands of many filtration applications. For even finer
filtration, ask about our unique, state-of-the-art SKMTM composite
filters. |
