Features & Benefits

The HAZ Series is engineered for extreme-duty slurry handling where abrasive materials and solid buildup can impact pump performance. Its integrated agitator system continuously mixes settled solids, allowing the pump to maintain flow while restoring sump capacity.

High-chrome iron components across the impeller, agitator, and wear plate provide superior resistance to wear, ensuring long service life even in aggressive slurry conditions. This combination of durability and performance reduces maintenance requirements and operational downtime.

The availability of MSHA-compliant configurations makes the series suitable for mining applications requiring strict safety and operational standards.

Construction and Operational Design

The HAZ Series is constructed using hardened ductile iron for the volute and high-chrome iron for critical wear components. This material combination provides both structural strength and exceptional resistance to abrasion.

Each pump is equipped with a dual mechanical seal system to protect the motor from slurry intrusion. The submersible motor operates at approximately 1750 RPM and is designed for continuous-duty performance under heavy loads.

Class H motor insulation allows for operation in higher temperature environments, while built-in thermal and amperage overload protection safeguards the motor during extended use. Stainless steel shaft components and rugged bearings further contribute to long-term reliability.
