Product Description

Filter

Filter chambers are constructed of mild steel with hard rubber lining (3 mm) on the interior and corrosion resistant paint (2 coals) on the exterior.

A flanged tangential inlet is standard, along with a bottom outlet and drain.

Stainless steel eyebolts with handwheels hold the powder coated steel cover in place. The lifting device provides for mechanical movement of the cover for maintenance purposes. An air release valve positioned on the cover, is also used as the return line during pre-coating.

A pressure gauge (0-60 PS1) is supplied with a corrosion resistant guard.

Fitter media suited for the application is placed between the rigid polypropylene filter discs. Filler media of various materials and micron ratings are available- Ten (10) micron cellulose is standard.

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

Pump

Polypropylene centrifugal pumps are equipped with TEFC, flange mounted motors- Mechanical seal is MEFIAG CRS-25/B with silicon carbide faces. Pump shaft is stainless steel. The motor starter is mounted in corrosion resistant, water tight NEMA 4 enclosure.

Slurry Tank

Slurry tanks are mild steel construction with an interior of hard rubber (3 mm) and an exterior of corrosion resistant paint (2 coats). They are used to facilitate pre-coating and addition of activated carbon (if required), as well as solution make-up and priming of the pump. The slurry tank can also be used to store solution from the filter chamber during changing of media or maintenance.

Pre-coating provides superior filtration and extends the life of the filter media.

Piping, Valves and Connections

Piping, valves, and connections are all CPVC construction.

Suction of the pump is piped to permit flow from the solution tank, slurry tank, and the filter chamber.

X-Construction

X-construction is used for more aggressive solutions such as acid copper, acid zinc, and acid tin. The lifter chamber and slurry tank are outside rubber lined, the base and cover are powder coated and the pump shaft is titanium.
