1. Wear Plates & Wear Rings (Spectacle Plates & Cutting Rings)
Concrete pump hopper systems demand high abrasion resistance to prevent aggregate wear and pressure loss. Bomanti produces precision-ground spectacle wear plates and cutting rings equipped with DURO 22 hardfacing alloys and Tungsten Carbide inlays.
Spectacle Wear Plates (DN200 / DN230 / DN260):
DN200 Sizes: Cross-reference part numbers 240111005, 229488005, 403095.
DN230 Sizes: Cross-reference part numbers 261122002, C00178700.
DN260 Sizes: Cross-reference part numbers 571295, 519314, 540 D22.
Cutting Rings / Wear Rings (DN200 / DN230):
Precision-machined for optimal sealing against spectacle plates during S-valve switching.
Common cross-references: 251026008, 251031006, 251036008, 251231000, 261611005.
2. S-Valves, S-Tubes & Transfer Assemblies
Our replacement S-Valves are cast from high-tensile, wear-resistant alloy steel to maintain continuous concrete flow under extreme hydraulic pressure.
Featured Models: S-Valve 2018N, 2318N, and 2018 Ø90 transfer tubes.
Complete Assemblies: Includes heavy-duty swing levers, slewing housings, upper/lower housing assemblies, and wear bushes engineered for maximum structural life.
3. Rubber Delivery Pistons, Piston Rams & Seal Kits
To prevent slurry blowby and preserve suction power inside delivery cylinders, Bomanti manufactures vulcanized rubber delivery pistons and elastomeric seal kits designed for harsh operating temperatures.
DN200 Piston Rams: Part numbers 019004000 / 19004000.
DN230 Piston Rams: Part numbers 262893000 / 19003001.
Complete Seal Kits & Backings: Polyurethane guide rings, NBR piston seals (e.g., 080372004, 080373003), dust scrapers, and steel backing flanges.
4. Concrete Delivery Pipes, Boom Elbows & Snap Clamps
We supply full pipeline systems engineered to withstand continuous friction from aggressive concrete mixes across long distribution distances.
Snap Clamps & Couplings: Quick-release adjustable snap clamps ($5.5”$ and $6”$ sizes), wedge clamps, and heavy-duty flange gaskets.
Delivery Pipes & Boom Elbows: Induction-hardened twin-wall pipelines, seamless concrete delivery pipes, and wear-resistant boom elbows.
Delivery Cylinders: Precision-honed chrome-lined cylinders built to exact stroke lengths.
