The perfect process

Pall’s Advanced Metal Medium Technology

Our metal medium portfolio consists of:

  • Sintered random metal fiber - DYNALLOY®, PMF®,
  • Sintered powder metal - PSS®
  • Sintered and unsintered wiremesh – DYNAMESH®, RIGIMESH®, SUPRAMESH®
  • Sintered composite medium
  • The properties of each of these medium are uniquely engineered to meet filtration challenges of capturing hard contamination and soft particulates such as gels and fish eyes

 

DYNALLOY® Filter Medium

Superior performance starts with the creation of the metal fiber. In our proprietary manufacturing process, metal fibers begin with wire drawing from stainless steel and other metal alloys. These microscopic filaments, as much as 30 times finer than a human hair and finer are sinter-bonded to form a durable, porous structure containing no binders. When fibers of different diameters are laid together, it results in a porous depthstructure that is extremely effective in capturuing hard and deformable gel-type contaminants. It also provideshigh dirt-holding capacity resulting in longer life with very low pressure drops. Strong sintering process along with metallic construction enables the medium to withstand temperatures as high as 1200˚F/ 649˚C and pressures up to 3,000 psid/207 bar without sacrificing filtration properties.

 

PMF Filter Medium

Our proprietary method of creating the PMF porous metal fiber filter medium results in a highly uniform structure with consistent filtration properties.

 

This medium consists of sintered stainless steel fibers configured to create a continuous tapered pore structure. The downstream region contains pores of a consistent diameter that provide reliable, absolute level filtration. The upstream section is made up of continuously varying pores from large to small, providing optimum pre-filtration. The unique structure of the

PMF medium maximizes dirt capacity, resulting in a long service life.

 

Dynamesh Filter Medium

Dynamesh is our precision-woven wire cloth, surface type filter media, specially suited for applications with adverse pressure conditions and low contaminant loading. It's available in a variety of weaves and stainless steels ranging from 5µm to 400µ.

 

PSS Filter Medium

Our PSS media is constructed of stainless steel powders. The media are manufactured by a proprietary process that produces an open matrix of particles, all sinterbonded to each other at the contact points. Our unique powder laydown and sintering techniques are designed to attain an increased void volume and maximum uniformity. The increased void volume results in a significant increase in dirt holding capacity enabling long on-stream life. The service life between cleaning cycles is typically two or more times longer, resulting in fewer cleaning interruptions during polymer processing. As a result, your total cost of filtration is greatly reduced.

 

PSS media also delivers a much finer removal efficiency at an equal or lower pressure drop. This improvement, coupled with its excellent fluid shear characteristics, makes our PSS medium an ideal solution for polymer filtration applications where gel control is essential.

 

PMM Filter Medium

Pall’s porous metal membrane (PMM) medium is an extremely robust composite of stainless steel mesh and stainless steel powder. This structure is often leveraged as a drainage material or as a gel control layer in Pall filter element designs and offers great strength, permeability, and a smooth surface.

 

DESIGN, DEVELOP, DELIVER

Pall has a long and successful history of developing customized polymer filter elements for high viscosity polymer processes. Whatever the end-product (fiber, resin or film) or end use (packaging, textile, electronic, medical), we have the experience and capability to customize a solution that is unique to your process and challenge. The fact that we design all critical components of polymer filtration systems – from the microscopic fibers used in our sintered metal fiber media to valves, segment filter elements, polymer candle cartridges and complete filter housings makes us uniquely capable to create a product solution that is right for you.

 

In addition, our sophisticated modeling capabilities accurately predict the pressure drop and residence type of the polymer through the entire filter r system ensuring a solution that is optimal for your process.

 

We are the only company in the world that provides totally integrated polymer filtration solutions, and our extensive experience gives us proven insight into how to meet the ever-increasing demands on film, fiber, and resin manufacturers.

This technical service involves extensive work both in the SLS laboratories, and in some instances on site.

 

Included as part of Pall’s extensive test facilities is a polymer melt extrusion test laboratory.

This test facility consists of a polymer dryer, extruder, feed pumps, filter housings, and associated controls and monitoring equipment. It is used in the development and optimization of filter media and element design for polymer melt applications. It also provides a very accurate means of predicting polymer filtration performance and a means of comparing filtration performance to other media and element designs. Test housings are available for flat sheet media, segments, and pleated elements. The capabilities include permeability and filter life determinations in actual polymer melt filtration service.
