Flo King Poly-Spun Filter CartridgesFlo King Poly-Spun
Disposable Filter Cartridges
These high-purity, all-polypropylene disposable filter cartridges are ideal for the rigorous demands of the metal finishing and allied industries.

Just insert the Poly-Spun cartridge directly into the Flo King pump and begin filtering. No pre-cleaning is required because Poly-Spuns do not contain any resins, binders, lubricants, anti-static agents or other impurities that can contaminate solution.

Micron Ratings and Lengths
Poly-Spuns are available in lengths of 4, 6, 10, 15, 20, 30, and 40 inches (10, 15, 25, 38, 50, 75, and 100 cm) and in a wide range of micron ratings.

What They Remove
Poly-Spuns primarily remove particulates and other solids visible to the naked eye. These cartridges will not remove dissolved metals or organic impurities unseen by the naked eye. They are especially recommended for the removal of fine to moderate-size particles.

Poly-Spun consists of hundreds of layers of bonded polypropylene fibers. Because these fibers differ in size and orientation, the Poly-Spun is like a multi-porosity chamber, trapping a wide range of particle sizes. Large particles are typically captured on the outer filter while smaller particles are trapped deep inside, where the filter fibers are more densely packed. For example, a 20-micron Poly-Spun can remove much smaller particles while preserving the high flow rate and agitation of the Flo King filter system.

After use, dispose the cartridge in accordance with applicable environmental regulations for your application.

What is a Micron Rating?
The micron is a measure of size that is used by filter manufacturers. A micron (μm) is a micro-meter (1 millionth of a meter), or 1 thousandth of a millimeter. There are 25.5 microns in 1 thousandth of an inch. The diameter of a human hair is about 90 microns.

Micron ratings refer to the particle diameter that the cartridge can remove from solution with a high degree of efficiency. For example, a 20-micron filter cartridge can be expected to remove the majority of 20-micron and larger particles from solution.

The higher the micron rating, the coarser the filter cartridge. So a 50-micron cartridge has larger pore openings than a 20-micron cartridge and can be used to remove larger particles.

Which Micron Rating Should You Use?
For practical purposes, here are some guidelines for selecting disposable filter cartridges to use with a Flo King in-tank pump:

• 20 micron is a very popular size for most electroplating and associated metal-finishing solutions.

• If the 20-micron cartridge is not fine enough to remove tiny particles from solution, the 10-micron cartridge is another common alternative.

• In some cases, 5 or 1 micron is specified, but not nearly as often as the larger micron ratings. Cartridges with very low micron ratings are tightly spun and will reduce the flow rate and agitation of the pump. They may also clog prematurely if larger particles are removed from solution, leading to frequent, costly filter cartridge changes.

• If the solution contains lots of solids and the 20-micron cartridge clogs too quickly, the 50- or even 75-micron cartridges can be used. The larger micron ratings have a higher dirt-holding capacity.

• Micron ratings may not be comparable among different manufacturers. In other words, if you have 20-micron cartridges from two different manufacturers, you may find differences in dirt-holding capacity, flow rate, and other performance features.

Poly-Spun Closeup

Poly-Spun is a high-quality, long-lasting disposable filter cartridge especially recommended for the removal of fine to moderate-size particles. Poly-Spun consists of hundreds of layers of thermally bonded polypropylene fibers. Because the fibers differ in size and orientation, the Poly-Spun is like a multi-porosity chamber, trapping a wide range of particle sizes.

 

Filter Cartridges Case

Flo King filter cartridges are available individually or by the case.

 

Poly-Spun on Pump

Insert Poly-Spun directly into Flo King pump or into Double or Quad Cartridge Holder. Then tighten Filter Screws to hold cartridge securely.

 

WHEN SHOULD YOU CHANGE FILTER CARTRIDGES?
How do you know when it's time to change filter cartridges on a Flo King in-tank pump?

First, you can lean the pump back and visually inspect the cartridge. Check to see if there is a significant build-up of particulates or other solids on the exterior.

Second, establish a maintenance schedule when you first install the Flo King pump. The schedule should be based on daily observations of the cartridge for each process tank. For example, you may find that every week or so, you need to change the cartridge on a plating bath, but more freqently in a high-production cleaner tank, or less frequently in a clean laboratory application.

Third, watch for a reduction in solution movement. As the cartridge clogs appreciably, the flow rate of the pump will decrease, and the solution agitation and movement will diminish.
