Product Overview
SV / SVR vertical sump pump is a heavy-duty vertical centrifugal slurry pump designed for handling abrasive, high-density and corrosive slurries.
The pump can operate normally without shaft seal water and does not require shaft gland sealing, making it suitable for difficult working conditions with insufficient suction volume.
SV series (SP type) uses high-chrome alloy wetted parts, while SVR series is lined with rubber or polyurethane for handling corrosive slurry.
Key Features
- Vertical cantilever design, no submerged bearing required
- Can operate without shaft seal water
- Suitable for high density and abrasive slurry
- Optional high chrome alloy, rubber or polyurethane wetted parts
- Double suction impeller reduces axial load
- Stable operation with low vibration
- Easy maintenance and long service life
- Suitable for continuous heavy-duty operation
Applications
SV / SVR vertical sump pump is widely used in:
- Mining and mineral processing
- Coal washing plants
- Power plant ash handling
- Metallurgy industry
- Chemical industry
- Sand and gravel handling
- Industrial wastewater treatment

FAQ
Q1: What is SV vertical sump pump used for?
A: It is used for transporting abrasive and corrosive slurry in mining, coal washing and industrial applications.
Q2: What is the difference between SV and SVR pumps?
A: SV uses high chrome alloy for wear resistance, while SVR uses rubber lining for corrosion resistance.
Q3: Can this pump operate without seal water?
A: Yes, it can operate without shaft seal water.
Q4: Does it require submerged bearings?
A: No, it uses a cantilever shaft design without submerged bearings.

Design Features of Vertical Centrifugal Pump
Bearing Assembly -The bearings, shaft and housing are generously proportioned to avoid problems associated with the operation of cantilevered shafts in the first critical speed zones. The assembly is grease lubricated and sealed by labyrinths; the upper is grease purged and the lower protected by a special flinger. The upper or drive end bearing is a parallel roller type whilst the lower bearing is a double taper roller with preset end float. This high performance bearing arrangement and robust shaft eliminates the need for a lower submerged bearing.
Column Assembly – Completely fabricated from mild steel. The SPR model is elastomer covered.
Casing – Has a simple bolt-on attachment to the base of the column. It is manufactured from a wear resistant alloy for the SP and from moulded elastomer for the SPR.
Impeller – Double suction impellers (top and bottom entry) induce low axial bearing loads and have heavy deep vanes for maximum wear resistance and for handling large solids. Wear resistant alloys, polyurethane and moulded elastomer impellers are interchangeable. The impeller is adjusted axially within the casting during assembly by external shims under the bearing housing feet. No further adjustment is necessary.
Upper Strainer – Drop-in metal mesh; snap-on elastomer or polyurethane for SP and SPR pumps. Strainers fit in column openings.
Lower Strainer – Bolted metal or polyurethane for SP; moulded snap-on elastomer for SPR.
Discharge Pipe – Metal for SP; elastomer covered for SPR. All wetted metal parts are completely rust protected.
Agitation – An external agitator spray connection arrangement can be fitted to the pump as an option. Alternatively, a mechanical agitator is fitted to an extended shaft protruding from the impeller eye.
Materials – Pumps can be manufactured in abrasive and corrosive resistant materials.
