Key Features

✔ Robust Construction – High-chrome alloy (Cr27, Cr30), rubber-lined, or Ni-Hard materials for extended wear life.
✔ Large Solids Handling – Capable of pumping particles up to 50–100mm (depending on model).
✔ Heavy-Duty Bearings – Grease or oil-lubricated for high-load conditions.
✔ Easy Maintenance – Back pull-out design for quick impeller and seal replacement.
✔ Multiple Sealing Options – Expeller, mechanical, or gland packing seals.

Typical Applications

Sand & Gravel Dredging – River, lake, and sea dredging operations.
Mining & Mineral Processing – Tailings transport, ore slurry pumping.
Construction – Slurry transfer in tunneling and foundation work.
Coal Washing Plants – Handling coal slurry with high solids content.

Selection Guide

A. Choose the Right Material

High-Chrome Alloy (A05, A49, Cr27, Cr30) – Best for highly abrasive slurries (e.g., sand, gravel).
Rubber-Lined (Natural, Neoprene) – Better for corrosive slurries with medium abrasion.
Ni-Hard – Extreme wear resistance for long-term heavy-duty use.

B. Select the Proper Seal Type

Expeller Seal – Default for abrasive slurries (no external water needed).
Mechanical Seal – For fine slurries (requires clean flush water).
Gland Packing – Low-cost option but requires regular adjustment.

C. Determine Drive Configuration

Direct Coupling – For fixed-speed applications.
Belt Drive – Allows speed adjustment for varying conditions.
Hydraulic Drive – Used in mobile dredging setups.
