The VSD Vertical Sump Duty Slurry Pump is a high-performance, centrifugal solution specifically engineered for the demanding task of transporting abrasive, high-density slurries and large particles from deep sumps. By eliminating the need for shaft seals and sealing water, the VSD series optimizes operational efficiency and reduces maintenance overhead in the most challenging industrial environments.
Designed for versatility and stability, these pumps feature an advanced guide bearing construction that expands their application range to deeper levels while ensuring steady operation. With available configurations in both abrasion-resistant metal alloys and moulded elastomer liners, the VSD pump provides a customizable, heavy-duty solution for the metallurgical, mining, coal, and power industries.
| Pump Type | Vertical Centrifugal Slurry Pump | Seal Requirement | No shaft seal or sealing water needed |
|---|---|---|---|
| Material Options | Wear-resistant Alloy / Elastomer / Polyurethane | Bearing Type | Parallel Roller (Upper) / Double Taper Roller (Lower) |
| Column Design | Mild Steel / Elastomer Covered (VSDR) | Impeller Type | Double Suction (Top and Bottom Entry) |
| Lubrication | Grease lubricated with labyrinth seals | Strainer Options | Metal Mesh / Polyurethane / Elastomer |
| Application Fields | Mining, Coal, Power, Metallurgical | Special Feature | External Agitator Option Available |
Wet parts are constructed from premium abrasion-resistant metals or rubber liners to withstand harsh slurry erosion.
The seal-free design removes the need for sealing water, significantly lowering operational complexity and downtime.
Integrated guide bearing construction ensures vibration-free operation even in deeper sump applications.
Double suction impellers with deep vanes are engineered to process large solids without clogging.
Interchangeable impellers and casing materials allow the pump to be tuned for specific corrosive or abrasive media.
Generously proportioned shafts and housings avoid critical speed zones, eliminating the need for submerged bearings.
Choose between high-chrome alloys or elastomers based on slurry acidity and abrasion levels.
External shim adjustments under bearing housing feet ensure perfect axial alignment.
Optimized cantilevered shaft design ensures stable operation within first critical speed zones.
All wetted metal parts are treated with industrial-grade rust protection for longevity.
Optional mechanical agitators or spray connections to prevent solids from settling.
Available in standard mild steel or elastomer-covered VSDR models for corrosive environments.
| Feature | Standard Sump Pump | VSD Vertical Slurry Pump |
|---|---|---|
| Seal Maintenance | Frequent seal replacements | Zero shaft seal maintenance |
| Water Usage | Requires sealing water | No sealing water required |
| Service Life | Moderate in abrasive media | Extended due to wear-resistant liners |
| Operating Depth | Limited suction capability | Optimized for deeper level duty |
| TCO (Total Cost) | Higher operational expenses | Lower lifecycle cost (OPEX) |
The VSD (Vertical Sump Duty) pump features an added guide bearing construction, allowing it to operate more steadily at deeper levels and providing a wider application range than standard SP models.
No. Thanks to the high-performance bearing arrangement (parallel roller upper and double taper roller lower) and a robust shaft, the need for a lower submerged bearing is completely eliminated.
For corrosive environments, the VSDR model with elastomer-covered columns and moulded elastomer liners is recommended to provide maximum chemical resistance.
Yes, it is specifically designed for abrasive, large particle slurries. The double suction impellers with heavy deep vanes ensure maximum wear resistance and efficient solids handling.
Yes, we offer two agitation options: an external agitator spray connection or a mechanical agitator fitted to an extended shaft protruding from the impeller eye.
They are primarily used in the Mining, Metallurgical, Coal, and Power sectors for transporting tailings, mineral slurries, and ash.
