Vertical Sump Slurry Pump – SV

The Vertical Sump Slurry Pump – SV is a cantilever-type vertical centrifugal slurry pump designed for continuous handling of abrasive and high-density slurry in sump and pit applications. The vertical arrangement allows the pump to operate directly in the sump without submerged bearings or a conventional gland water system, making it suitable for applications where conventional horizontal pump suction arrangements are difficult to maintain. The SV configuration uses wear-resistant metal wet-end components for abrasive-duty slurry handling and incorporates a double-suction impeller to help reduce axial loading. The pump is suitable for mining, coal washing, mineral processing, metallurgy, sand and gravel handling, and industrial processes involving solid-containing liquids. Its modular bearing assembly and accessible structure also simplify inspection and routine maintenance.

Product Overview

The Vertical Sump Slurry Pump – SV is designed for handling abrasive and high-density slurry collected in sumps and pits.

Unlike conventional horizontal slurry pumps, the vertical arrangement allows the wet end to operate directly in the slurry sump. The cantilever structure eliminates the need for submerged bearings, while the pump operates without a conventional gland water system.

The SV configuration uses wear-resistant metal wet-end components for abrasive-duty applications and is suitable for continuous slurry handling in mining and industrial processes.

Typical applications include:

Mining and mineral processing
Coal washing
Metallurgical processing
Sand and gravel handling
Industrial wastewater containing solids
Slurry collection and transfer

Key Features of SV Vertical Sump Pump

Cantilever Vertical Design

The bearing assembly is positioned above the slurry, while the pump wet end operates inside the sump. This cantilever arrangement eliminates submerged bearings and helps reduce exposure of the bearing assembly to abrasive slurry.

No Conventional Gland Water

The pump operates without a conventional gland water system, reducing auxiliary water requirements and simplifying the sealing arrangement.

Wear-Resistant Metal Wet End

The SV configuration uses wear-resistant metal wetted components for abrasive-duty slurry handling.

Main wetted components include:

Impeller
Pump casing
Strainers
Other wetted components

Material selection should consider slurry concentration, particle size, abrasiveness, impact conditions, and operating temperature.

Double-Suction Impeller

The double-suction impeller provides flow entry from both sides and helps reduce axial loading on the bearing assembly. The hydraulic design provides suitable flow passages for slurry containing solid particles.

Easy Maintenance

The modular bearing assembly and accessible vertical structure simplify inspection and replacement of selected pump components, helping reduce maintenance downtime.

SV and SVR Configurations

The SV and SVR configurations provide different wet-end material solutions within the vertical sump pump range.

SV uses wear-resistant metal wet-end components and is intended for abrasive-duty slurry applications where metal wear and impact resistance are required.

SVR uses an elastomer-lined wet end and is intended for applications where rubber lining is preferred according to the slurry characteristics.

The appropriate configuration should be selected according to slurry abrasiveness, particle size, concentration, temperature, and other operating conditions.

Typical Applications

Mining and Mineral Processing

Suitable for:

Sump slurry transfer
Mineral slurry handling
Process slurry circulation
Abrasive sump drainage

Coal Washing

Used for coal slurry, solid-containing process water, and slurry collected in process sumps.

Metallurgical Processing

Suitable for abrasive process slurry and solid-containing process fluids.

Sand and Gravel Handling

Used for sand slurry, sediment, and abrasive solid-particle transportation.

Pump Structure

The main components include:

Bearing assembly
Shaft
Column assembly
Pump casing
Double-suction impeller
Strainers
Discharge pipe

The bearing assembly remains above the slurry while the wet end is positioned inside the sump. The vertical cantilever structure allows the pump to operate without a lower submerged bearing.
