Reusable filter cartridges are available in lengths of 4, 6, 10, 15 and 20 inches (10, 15, 25, 38 and 51 cm).

We offer two types of reusable cartridges — the Standard style and the Permacore style.

Most customers prefer the Permacore Magnum Reusable Filter Cartridges if they are mounted on Flo King pumps and use 10" or longer cartridges. The Permacore has a machined polypropylene head that fits snugly into the pump and provides a secure long-term mount.

The Permacore and Standard Magnum cartridges are otherwise identical, but the Permacores are available only in lengths of 10, 15 and 20 inches.

Both styles include a reusable filter blanket, an inner polypropylene core, and a plastic Web to hold the assembly together.

The 1-, 5- and 10-micron filter blankets are made of POLYPROPYLENE and are compatible with many neutral, mildly acidic and mildly alkaline solutions up to 200 F. The 10-micron filter blanket is our most popular material.

However, the polypropylene filter blankets will disintegrate in hard chrome plating and other highly concentrated chromic acid solutions — even at relatively low temperatures.

For chromic acid applications, use the Super Magnum reusable filter blankets, which are made of POLYESTER and available in 30 and 75 microns.
