Heavy-Duty Conical Apex Wear Sleeves & Liners for Slurry Desanding Units
In civil engineering applications—such as Tunnel Boring Machine (TBM) tunneling, Horizontal Directional Drilling (HDD), and diaphragm wall construction—slurry separation plants process high volumes of coarse solids, gravel, and sand. Desanding hydrocyclone inner walls and lower discharge sleeves face severe impact and abrasion. Replacing complete metallic or cast-iron cyclone bodies due to localized apex wear is inefficient and costly.
Our heavy-duty Conical Apex Wear Sleeves, Rubber Liners, and Cylindrical Bushings provide slurry separation plant operators and civil tunneling contractors with a replaceable wear barrier that protects structural housings and reduces overhaul costs. Explore our full range of civil slurry desanding equipment and replacement wear parts.

Manufacturing Standards & Quality Control
- High-Resilience Elastomer Formulation: Molded from synthetic elastomer blends engineered to absorb and rebound abrasive sand impacts without localized tearing.
- Compression Molding Tooling: Produced under high-pressure hydraulic molding presses, ensuring uniform density and preventing internal laminar separation.
- Chemical & Oil Resistance: NBR/Polyurethane options are resistant to diesel fuel, lubricants, and polymer drilling additives commonly used in slurry tunneling.
Maintenance & Refurbishment Installation Guidelines
- Housing Bore Cleaning: Prior to inserting a replacement sleeve, scrape clean the metallic housing bore to remove corrosion scale and sand grains.
- Soapy Water Lubricant: Apply mild soapy water to the sleeve exterior to facilitate insertion into the housing. Do not use petroleum grease on standard natural rubber liners.
- Inspect Liner Overlap: Confirm the top lip of the conical wear sleeve seats flush against the upper cone internal shoulder to eliminate fluid catch points.
Frequently Asked Questions (FAQ)
Q: Can these wear sleeves be utilized in cast iron desanding cones on tunneling slurry plants?
A: Yes. These replacement conical sleeves are designed to fit standard cast iron and steel hydrocyclone shells used on civil slurry separation units.
Q: How do these rubber liners perform compared to solid polyurethane cones in high-gravel applications?
A: High-elasticity rubber and Shore 85A polyurethane sleeves absorb high-energy impacts from larger coarse sand and fine gravel, preventing brittle chipping under heavy TBM slurry loads.
Q: What dimensions are required to confirm fitment for custom slurry cones?
A: Provide top outside/inside diameter, bottom discharge diameter, total overall height, and taper angle. We maintain a large library of standard molds and can manufacture custom dimensions with short turnaround times.
