Slurry Pumps
EVERGREEN slurry pumps utilize high-chrome alloy (Cr27-Cr30) metallurgy, exhibiting superior fracture toughness (≥18 J/cm²), tensile strength (≥750 MPa), and abrasion resistance versus conventional pumps.
When abrasive media achieve high-velocity impingement on wetted surfaces, our phase-hardened microstructure provides sacrificial carbide buffering through optimized impact energy dissipation. This engineered material response simultaneously resists three-body abrasion from particulate cutting while minimizing spall formation – reducing mass loss by 40-60% and extending mean time between failures (MTBF) in severe-duty applications.
Slurry Pump Applications
Abrasive Slurry Applications (Mining | Dredging | Mineral Processing)
EVERGREEN slurry pumps prevent microcutting wear during transport of highly abrasive media (coal, silica sand ≥6 Mohs, mineral concentrates, frac sand) through chromium carbide reinforcement (27-30% Cr). Our proprietary metallurgy achieves ≤0.8 mm/1000hr wear rates in ASTM G65 testing, extending service intervals by 3-5x versus conventional pumps in ore transfer and dredge discharge applications.
High-Viscosity Media Handling (Power FGD | Wastewater | Tunnel Boring)
Engineered for non-Newtonian fluids (thixotropic sludge, >70% solids pastes, thickener underflows), EVERGREEN’s large-volute designs maintain turbulent flow regimes at viscosities ≤1,500 cP. Torque-optimized impellers prevent solids packing, enabling continuous pumping of CIP slurries and bentonite drilling muds without flow-induced downtime.
Abrasion Resistant Slurry Pumps
How a Slurry Pump Works: Engineering Principles
Transfers abrasive solid-liquid mixtures via centrifugal force while managing wear through specialized engineering.
Operational Sequence
- Fluid Entry
Slurry enters through suction liner at eye of impeller
Acceleration begins immediately upon contact with rotating blades - Centrifugal Acceleration
Impeller rotation (typically 300-1500 RPM) imparts kinetic energy
Solids suspended via turbulent flow regime maintenance
Critical Design Factor: Impeller vane angle optimized for particle size distribution - Pressure Conversion
Volute casing converts velocity to pressure energy
Progressive volute geometry reduces internal velocities to minimize wear - Discharge
Pressurized slurry exits through discharge flange
System curve determines operating point on pump performance curve
Critical Wear Management Systems
| Impeller | Closed-vane design with hardened alloys (Cr27, Ceramic) |
| Volute | Replaceable liners with rib-reinforced thickness |
| Seals | Expeller + gland water injection dual protection |
| Shaft | Tungsten carbide sleeves in abrasion zones |
