Models Slimline, PSHR 2410 and PSD 688 Filters
Models Slimline, PSHR 2410 and PSD 688 pumps come equipped with spin-on absorptive cartridges. The
cartridge absorbs water and provides particulate filtration. As the maximum water-holding capacity is
reached, a reduction in flow will occur, indicating that the cartridge must be replaced.
These patented
Aquacon filter cartridges have a unique high-capacity inner filter media which removes all
free and emulsified water from hydrocarbon fuels down to less than 5 in the effluent. Absorbed water is
chemically locked into this media.
When a fuel cartridge reaches its water holding capacity, its accordion pleats swell and cause an increase in
the differential pressure which signals the operator to change the cartridge. Solid contaminants are removed
by the cartridge’s two particulate filter media layers.
The pleated accordion style design provides a large surface area for maximum dirt holding capacity. Models
are offered for particulate filtration down to 1/2 micrometer size with 98% plus efficiency. Performance is
not affected by the presence of common surface active agents.
