What this product is designed to do
Ceramic-coated sleeves are presented in the supplied technical brochure as wear- and corrosion-protection components for selected pump and rotating-equipment applications. Confirm sleeve design, substrate, coating system and current supply capability with Darius before specification.
Product details
- The 2018 source brochure describes ceramic-coated sleeves and special tungsten-carbide or chrome-carbide coating options.
- No universal dimensions, coating thickness, hardness, tolerances or service-life values are published here; obtain the current drawing and technical specification for the exact application.
Key product points
- Designed to address wear and corrosion on selected sleeve surfaces.
- The supplied brochure also mentions tungsten-carbide and chrome-carbide coating options for special requirements.
- Selection depends on sleeve dimensions, base material, shaft fit, gland-packing arrangement, fluid chemistry, temperature and wear mechanism.
Where to use
- Slurry pumps and ash-slurry pumps
- Raw-water pumps
- Chemical pumps and acid pumps (after compatibility review)
- Clinker-grinder shaft protection
- Warman-type sand pumps
- Paper-mill machines and screen pumps
- Selected gland-packing arrangements where the sleeve design is suitable
Practical checks before the job
- Record equipment make/model, shaft and sleeve dimensions, fit, runout and sealing arrangement.
- Describe the service fluid, solids content, pH/chemistry, temperature, operating speed and observed wear/corrosion pattern.
- Confirm the coating system and substrate compatibility with the current engineering drawing and technical specification.
- Agree machining allowance, finish, dimensional tolerances, coating inspection and acceptance criteria before manufacture or refurbishment.
- Install and commission under the pump/equipment OEM procedure; check gland packing, alignment, lubrication and leakage during the initial run.
Selection check: The available sleeve brochure is from 2018 and identifies Teknnovation Engineers Pvt Ltd. Darius must confirm the current supplier/partner relationship, manufacturing route, product availability and approved technical data before accepting orders.
This guide supports product discovery and enquiry preparation. It is not a full operating instruction, welding procedure or installation specification. Confirm the exact grade, substrate, operating conditions and latest manufacturer technical and safety data sheets. Follow the approved site procedure and engineering approval where applicable.
