Key Engineering Advantages
Robust Double-Casing Design: External heavy-duty cast iron outer frame holds internal wear-resistant alloy liners, providing maximum operational safety and high pressure resistance during multi-stage pumping.
A05 High-Chrome Wet-End Parts: Volute liner, impeller, and frame plate liner insert are cast from A05 high-chrome iron (Cr27), delivering exceptional resistance to severe erosive slurry wear.
Replaceable Wear Liners: Internal liners are fully bolted and replaceable, dramatically cutting long-term maintenance costs and component replacement time.
Versatile Dynamic Expeller Seal: Features an expeller seal system that eliminates the need for external gland sealing water in most applications, preventing liquid dilution and seal failure.
Target Applications
Mining & Mineral Processing: Primary ball mill discharge, hydrocyclone feed, flotation concentrate, and heavy tailings transport in gold, copper, and iron mines.
Coal Preparation Plants: Transferring heavy medium coal slurry, fine coal washwater, and refuse tailings.
Power Plant Ash Handling: Bottom ash, fly ash slurry transport, and FGD limestone slurry recirculation in thermal power plants.
