The KZN Series Advantage: Versatile Performance for Abrasive Slurries
The BJM Pumps KZN Series is engineered for heavy-duty slurry, sand, and sludge applications where durability and solids handling are critical. Designed with hardened ductile iron construction and abrasion-resistant high chrome components, these pumps deliver reliable performance in demanding environments.
With a broad range from 5 HP to 50 HP, including standard, high-head (H), and high-flow (L) configurations, the KZN Series provides flexible solutions for a wide variety of industrial and construction applications.
Engineered for Abrasion Resistance and Solids Handling
The KZN Series incorporates high chrome iron components in key wear areas such as the impeller, wear plate, and agitator. These materials provide exceptional resistance to abrasion and extend pump life in harsh slurry conditions.
A built-in agitator continuously suspends solids, improving pumping efficiency and reducing clogging. The semi-open impeller design allows the pumps to handle high concentrations of abrasive solids, including particles up to approximately 1.5 inches.
Key Features & Benefits
- Abrasion-Resistant Construction: Hi-chrome iron components and hardened ductile iron volute
- Integrated Agitator: Prevents solids settling and improves slurry movement
- Flexible Performance Range: Standard, high-head (H), and high-flow (L) configurations
- High Solids Handling: Semi-open impeller passes up to ~1.5" solids
- Reliable Seal System: Double silicon carbide mechanical seals in oil-filled chamber
