Machined plastic parts for water & wastewater treatment
PHOTO NEEDED: CDS-machined water-treatment part (split sprocket or UHMW wear shoe), on a plain ground
Replacement and production parts for water treatment, wastewater and RO equipment, from clarifier sprockets and wear shoes to valve, pump and filter parts. Machined to your drawing, or from the worn part.

Clarifier and sludge collector parts
Inside a chain‑and‑flight collector
Rectangular clarifiers use chains and flights to scrape settled sludge to a hopper. Their sprockets, wear shoes and strips run underwater all day, and wear out. We machine the replacements.
PHOTO NEEDED: CDS-machined collector parts laid out together: split sprocket, carry and return wear shoes, wear strip, split bushing
- Drive and collector sprockets Solid or split, so they fit over the shaft without pulling it. For non-metallic collector chain.
- Carry and return wear shoes The pads on each flight that slide on the floor rail and the return track.
- Wear strips and return track UHMW strips the flights run on, top and bottom.
- Split bushings and bearing liners For headshafts and wall bearings, split so they replace in place.
- Shaft collars Solid or split collars that hold sprockets and shafts in position.
- Flight filler blocks Blocks that fill the gap where flights attach to the chain.

FAQ
Questions from water and wastewater plants
Yes. We machine end caps, housings, seal supports and other parts for RO and desalination units, to your drawing or from the worn part.
Plastic doesn’t corrode in chlorinated or salt water, and it’s lighter to handle and replace. That’s why it’s common for collector parts, fittings and chemical feed parts.
