Our CECO Mefiag brand CR Series - Chromic Acid Disc Filter Systems are special filtration units of polyvinylidene difluoride (PVDF) lined or solid PVDF construction. These units, which feature horizontal disc technology and capacities from 800 to 6,500 gph, are specifically for use in processes where chromic acid is involved (hard chromium, etching, etc.)
The MEFIAG® AdvantageMEFIAG® is recognized throughout the world as the leading supplier of high efficiency, high quality, horizontal disc filters for superior performance. Series 2500/4500/6500-CR is a design that incorporates the best that MEFIAG has to offer including PVDF construction and self-priming magnetic drive pump as standard.

Designed for the filtration of chromic acid solutions including etching of ABS.
  • Operating temperature to 190 °F (90 °C).
  • For plating tanks from 1,000 to approximately 3,300 gallons.

    All systems come with a KMSP self priming magnetic drive pump.Exclusive MEFIAG® stainless steel lifting device (for 4500 & 6500 Series) provides for simple mechanical movement of the cover for maintenance purposes. Just turn crank to raise lid. Then swing lid away to access filter media

Filter

Filter

 N/A Filter chambers are constructed of mild steel with a PVDF lining on the interior and corrosion resistant paint (2 coats) on the exterior.
A flanged tangential inlet is standard, along with a bottom outlet and drain.
Stainless steel eyebolts with hand wheels hold the powder coated steel cover in place. The lifting device provides for mechanical movement of the cover for maintenance purposes.

A pressure gauge (0-60 PSI) is supplied with a corrosion resistant guard.

Reusable filter media suited for the application is placed between the rigid PVDF filter discs. Filter media of various materials and micron ratings are available. Ten (10) micron polyester is standard.

All systems are mounted on a powder coated structural steel frame with casters for easy handling.
