Product catalog summary

Overview
The KREBS vMAX™ Vertical Cantilever Pump is designed for sump and process duties requiring reduced degradation of pumped solids and increased operational life. It is suitable for continuous abrasive slurry service without the need for sump level control or submerged bearings.

Applications
The pump is applicable in various industries including mining and mineral processing, power plants, and industrial processing. Specific applications include SAG mill discharge recirculation, cyclone feed, tailings, mill discharge, and handling heavy-duty abrasive slurries.

Specifications

Available sizes: 2”, 3”, 4”, and 6” with setting depths of 1.4m, 1.8m, and 2.1m.
Material: 27% chrome iron wear parts with a minimum hardness of 680 BHN.
Design: Cantilever design with no stuffing box seal or submerged bearings.
Features: Rigid 1040 steel shaft, integral discharge elbow, 8-vane impeller, separate suction wear plate, oversized suction strainer.

Performance Advantages

Reliable continuous operation without shaft deflection during loss of prime.
No impeller adjustments or water flush required.
Operates without automatic level controls, reducing downtime and maintenance.

Design Features

Recessed impeller allows slurry to run back down the discharge pipe with minimal impact.
High-performance expelling vanes prevent leakage.
Flared suction entry promotes prerotation of slurry and scours the sump floor.

Conclusion
The vMAX™ pump is an extreme duty vertical cantilever pump designed for sump and process duties, offering reliable performance and reduced maintenance needs. It is ideal for applications requiring the handling of large solids and abrasive slurries.

Extreme Duty Vertical Cantilever Pump for Sump and Process Duties The new “vMAX™” line of vertical cantilever hard metal pumps has been developed for conventional clean up sump duties and process duties that require reduced degradation of pumped solids. The fully recessed torqueflow cup style impeller design permits passing of pipe size solids and operation without the need for sump level control. The casing is configured for bottom suction only to prevent build up of solids in the bottom of the sump. Leakage from the back of the casing, through the life of the pump, is prevented by high performance...
