The KZN MAXDuty™ Advantage: Built for Extreme Wear Environments
The BJM Pumps KZN MAXDuty™ Series is engineered for the most aggressive slurry applications where standard pumps experience rapid wear. Featuring a patented split-case high-chrome volute and hardened abrasion-resistant components, these pumps deliver maximum durability, extended service life, and reduced maintenance downtime.
Designed for demanding industries such as mining, steel production, and sand processing, the MAXDuty™ Series provides continuous, reliable performance in high-abrasion conditions.
Engineered for Maximum Wear Resistance
The KZN MAXDuty™ Series is built with 28% high-chrome iron components in all critical wear areas, including the impeller, agitator, wear plate, and volute. This significantly increases resistance to abrasion from sand, sludge, and slurry.
A heavy-duty agitator keeps solids suspended during operation, improving efficiency and reducing sediment buildup. The semi-open impeller design allows the pump to handle high concentrations of abrasive solids while minimizing clogging.
The patented split-case volute design enhances both durability and serviceability, allowing faster maintenance and reduced downtime.
Key Features & Benefits
- Maximum-Duty Construction: High-chrome (28%) components for extreme abrasion resistance
- Split-Case Volute Design: Improves durability and simplifies maintenance
- Heavy-Duty Agitator: Keeps solids suspended for efficient slurry pumping
- Semi-Open Impeller: Handles high concentrations of abrasive solids
- Advanced Seal System: Double silicon carbide mechanical seals in oil-filled chamber
