ORRO Manufacturing Co., Ltd. supplies non-metallic precision parts for water and wastewater treatment, where chlorine, ozone, UV and continuous moisture attack metal components and where plastic and rubber parts must remain leak-free for years of unattended operation.
Typical Parts
- PVC and PTFE valve seats and liners — chemical-resistant sealing and flow control for dosing and control valves
- EPDM gaskets and seals — long-life sealing for flanges, membranes and pipework
- PEEK and Nylon bushings — corrosion-proof, self-lubricating bearings for valves and scrapers
- Ceramic diffusers and nozzles — abrasion and chemical resistant aeration and dosing components
- UHMWPE weir plates and wear strips — low-friction, corrosion-proof surfaces for clarifiers and sludge systems
Material Advantages
- PVC: Excellent chemical resistance and rigidity at low cost for pipework and fittings
- PTFE: Unaffected by chlorine, ozone and virtually all treatment chemicals
- EPDM: Outstanding resistance to water, ozone, UV and oxidation for long-life sealing
- PEEK: High-strength, corrosion-proof and dimensionally stable in hot, wet service
