Engineered Flow Paths

Engineering the Wear-Deflecting Flow Path

Polimak pneumatic conveying elbows utilize proprietary geometries and advanced linings to eliminate pipeline blowouts and minimize material degradation.

Impact Deflection

The Self-Protecting Vortex Chamber

Our proprietary pocket geometry traps a small portion of the conveyed material, creating a dense, rotating cushion. Incoming high-velocity particles impact this static boundary layer instead of the steel wall, completely neutralizing erosive wear.

Computational Fluid Dynamics

Every elbow radius is engineered using advanced CFD simulation to minimize pressure drop and prevent material degradation while maintaining continuous, high-velocity plant throughput.

Standard short-radius elbows cause extreme turbulence, leading to localized wear and immediate blowout risks. Our optimized flow paths distribute impact forces evenly across the curved surface.

Extreme Protection

Alumina Ceramic Armor

92%

Alumina Content

For the most abrasive bulk solids like cement, fly ash, and quartz sand, we line high-wear zones with high-purity alumina ceramic tiles. This diamond-hard barrier extends pipeline lifespan up to ten times.

Engineered with fine-grain crystalline structures to resist high-velocity sliding abrasion.
