BJM Pumps® is the top choice for the most difficult slurry, sand and sludge pumping applications. Used in lime slurries, mill scale, coal runoff sumps, washdown sumps, ash transfer, tailings ponds, slag pits, food wastes, silt removal, sand & gravel dewatering, barge & tank cleanout. 

Our KZN pumps are among our most popular pumps as they are engineered specifically for the tough applications you deal with in:

• Mining/Coal Mining
• Hydraulic Fracking
• Mineral Processing
• Steel Production
• Drilling Mud Transfer
• Slurry Transfer
• Sand and Gravel
• Lime Slurry
• Fly Ash

Key Benefits of KZN Series:

Abrasion-Resistant 28% Chrome Iron (600 Brinell, 57 Rockwell C) Components

• Agitator: Keeps solids from settling at the bottom to prevent clogging
• Wear Plate: Easily replaceable to keep pump performing like new longer
• Impeller: Slurry-type, semi-open design handles the most abrasive slurries
• Every KZN slurry pump is constructed with an abrasive resistant 28% chrome iron (600 Brinell, 57 Rockwell C) impeller, wear plate & agitator.

Superior Protection

• Class H motor insulation with integral amperage (FLA) and temperature overload protection
• Double silicon carbide mechanical seals in a separate oil-filled seal chamber
• Heavy duty lip seal to protect seal chamber from solids migration
• Hardened ductile iron volute with 300 Brinell hardness for twice the abrasion resistance of standard ductile iron

Top Discharge Design

• Portability and Durability: KZN pumps are not easily damaged when moved from one project to another and pushed/pulled into place
• Cooled by Pumped Liquids: KZN pumps can remove liquids to within inches of the bottom while side discharge pumps leave up to three feet of liquid because it must remain submerged to avoid overheating
• Slim Design: The largest KZN model has a maximum 22.75-inch diameter, making it fit in tighter spaces than side discharge pumps

KZNR Series Severe Duty Slurry Pumps

Some slurry solids are so abrasive that pump service life depends on an extremely hardened casting. BJM Pumps® KZNR Series pumps offer this level of casting through a proprietary process that hardens the ductile iron volutes to 71 Rockwell C (compared to Class 30 ductile iron for the KZN Series). The KZNR Series are severe duty slurry pumps that can stand up to extreme abrasiveness. For complete specifications, visit www.flowsolutions.com or call 860-631-3618.
