Commercial Trust & Engineering Warranty Charter
In mining procurement, trust is not requested: it is demonstrated. At SMAT Minerals, we transparently disclose what our Durango Central Warehouse inspection covers (Fiscal HQ at Mariano Salas #114): 1:1 dimensional assembly verification, industry standard drop-in fit assurance, and verified warehouse dispatch.
What We Test on Shop Bench
Every component dispatched undergoes rigorous dimensional and physical verification in our Durango facility prior to site shipment.
- Dynamic Balancing: ISO 1940 Grade G2.5 shop balanced to prevent bearing vibration.
- 1:1 Bolt Alignment: Template verification ensuring exact bolt-hole match with existing plant housings.
- Axial Clearance Check: Precise 0.75 mm clearance set to avoid internal recirculating erosion.
What Manufacturing Covers
Certified casting integrity backed by chemical spectrometry and ultrasonic non-destructive testing at partner foundries.
- ASTM A532 Alloy: High Chrome 27% Cr (>650 HB hardness) certified chemistry per batch.
- Casting Flaws: 100% replacement warranty against internal blowholes, porosity or shrinkage.
- Vulcanized Bond: High-resilience natural rubber with verified steel-substrate bonding.
When We Decline to Quote
Protecting your concentrator plant means knowing our operating limits. We never compromise safety for a blind sale.
- 1. Pumping / Cavitation: We decline quotes if suction NPSHa is severely deficient without piping redesign.
- 2. Flotation / Instability: We reject supply if excessive airflow rate destroys the quiescent mineral froth layer.
- 3. Filtration / Cloth Blinding: We decline standard filter cloths if ultrafine clay tailings lack conditioning.
Commercial Trust & Engineering Warranty Charter
Operational assurance at our Durango Central Warehouse. Clear clarity on assembly warranty, dimensional interchangeability, and technical application boundaries.
Every component and assembly undergoes metrological dimensional verification at our Durango facilities prior to dispatch. We guarantee 100% interchangeable fit with standard frames without field torch adaptations.
Impellers and rotating mechanisms undergo dynamic balancing on our test bench in Durango, verifying concentricity and vibration reduction prior to dispatch.
High Chrome 27% (A05) casting with verified hardness exceeding 650 HB (Brinell) for high-wear slurry duty, impact-resistant vulcanized elastomers, and engineering polypropylene for filtration.
Durango Warehouse facilities equipped with forklift maneuvering for loading onto rigid trucks, torton, or flatbed trailers with direct freight across Mexico.
Warranty Coverage Matrix: SMAT Durango vs. Partner Foundry
Components undergo 1:1 dimensional verification against standard casings, shaft rotation testing, and Brinell hardness inspection at our Durango warehouse prior to shipment.
100% replacement guarantee for dimensional interchange with C, D, E, F frames.
Certified manufacturing drawings and standardized casting tooling.
Pre-shipment visual and dimensional screening for surface defects.
Full replacement warranty against internal alloy fissures or structural shrinkage porosity.
Pre-shipment dynamic balancing and verification on our Durango test bench.
Rough static pre-balancing at manufacturing foundry.
We decline standard A05 or natural rubber quotes for acid leach solutions with pH < 2.0 above 60°C. These conditions require special alloys (Hastelloy, Titanium) evaluated strictly as custom projects.
We do not quote complete slurry skids or impeller specs if baseline flow, slurry SG, and particle abrasiveness are missing. Quoting blindly endangers your plant operations.
Yard warranty is voided if components undergo uncertified field structural welding or abrasive grinding at the mine site altering dynamic balance mass distribution.
Plant Commitment: Every spare part is covered by our 100% replacement warranty against manufacturing defects.
1:1 Dimensional Cross-Check & Physical Fit Verification Protocol
To safeguard assembly reliability in the field, every component dispatched from our Durango Central Warehouse is physically matched against standard frame dimensions (ANSI flanges, bolt circles, and shaft keyways) and checked for rotation concentricity and Brinell hardness (≥650 HB) prior to carrier loading.
