Product Description
Toyo VH Slurry Pumps
The Toyo VH Slurry Pumps provide heavy-duty pumping for dense, abrasive slurries containing settled solids. Their patented shaft-mounted agitator lifts sediment and creates a pumpable mixture. Therefore, the pump can transfer material that may settle around the inlet of a conventional slurry pump.
Moreover, the amphibious motor receives cooling from air or water. Consequently, operators can use suitable VH configurations while fully submerged, partially immersed or installed in an approved surface arrangement.
Amphibious Heavy-Duty Pump Design
Each Toyo VH slurry pump combines a semi-open impeller with large hydraulic passages. As a result, solids can move through the pump with fewer restrictions.
In addition, the heavy-duty shaft and bearing assembly supports demanding radial and axial loads. Meanwhile, two mechanical seals operate inside an oil bath to help protect the motor from the pumped slurry.

Together, these features support demanding solids-transfer, sediment-removal and slurry-handling duties.
VH Slurry Pump Performance
The European VH range provides capacities up to 210 m³/h. Moreover, suitable configurations can handle slurry containing solids concentrations up to 55% by weight.
In addition, standard agitator-equipped versions can handle particles up to 45 mm.
However, these figures represent limits across the overall range. Therefore, engineers should select each Toyo VH heavy-duty pump from its model-specific performance curve and solids-passage data.
Patented Agitator and Solids Suspension
The Toyo agitator mounts directly on the pump shaft. During operation, it loosens settled sand, sediment and sludge before directing the mixture towards the impeller.
Consequently, the Toyo VH Slurry Pumps can create a more uniform solids concentration around the suction area. Moreover, continuous agitation may reduce manual excavation and sump-cleaning requirements.
Nevertheless, the agitator cannot handle every solid material. Therefore, users should identify particle size, hardness, shape and concentration before selecting the pump.
Wear-Resistant Hydraulic Components
Toyo manufactures the impeller, wear plate and agitator from cast chrome iron containing approximately 24% to 28% chromium.
As a result, these components provide strong abrasion resistance for sand, minerals and industrial sediment. Moreover, selected alternative metallurgies, including stainless steel, may suit compatible corrosive or acidic slurries.
However, engineers should review the complete slurry chemistry before choosing materials.
Air- and Water-Cooled SP Motor
The SP motor allows the Toyo VH pump to receive cooling from surrounding water or ambient air.
Therefore, suitable configurations can continue operating when the liquid level drops below the complete motor body, provided the installation follows Toyo operating requirements. Consequently, the pump suits applications with fluctuating liquid levels.
The custom four-pole motor also provides a 1.25 service factor. As a result, it can accommodate changing loads associated with dense slurry transfer.
Adjustable Wear Plate
VH15 and larger European configurations include an adjustable wear plate. Therefore, technicians can restore the clearance between the impeller and wear surface as components gradually wear.
Consequently, regular adjustment can help preserve hydraulic efficiency and pumping capacity. Moreover, facilities may extend component life before replacing major hydraulic parts.
Side Outlet and Mixing Versions
Standard Toyo VH Slurry Pumps use a side outlet discharge. Alternatively, Toyo offers VHA and VHJ versions with three outlets for combined pumping and mixing applications.
In addition, high-head VH configurations support systems with longer discharge pipelines or greater elevation differences. Therefore, engineers can select the arrangement according to flow, head, slurry density and mixing requirements.
Operating Range
Published European series limits include:
- Maximum capacity: Up to 210 m³/h
- Solids concentration: Up to 55% by weight
- Particle size: Up to 45 mm
- Standard slurry temperature: Up to 60°C
- High-temperature version: Up to 80°C
- Permitted pH range: 4–14
- Maximum operating depth: 30 m
However, these limits do not apply simultaneously to every model. Therefore, users should confirm the specification of the selected pump.
Toyo VH Applications in India
The Toyo VH Slurry Pumps may support applications across India such as:
- Sand and sediment removal
- Industrial sump cleaning
- Mining and mineral processing
- Construction slurry transfer
- Tank and lagoon clean-out
- Dredging operations
- Quarry wastewater
- Abrasive sludge pumping
- Ash and process residue handling
- Settling-basin cleaning
- Heavy industrial slurry transfer
- Mixing and recirculation duties
Moreover, the amphibious design can suit installations with changing liquid levels. Nevertheless, engineers should review the solids characteristics, discharge distance and operating conditions for every project.
Selecting the Correct Toyo VH Pump
Correct selection depends on:
- Required flow and total head
- Slurry density
- Solids concentration
- Maximum particle size
- Slurry temperature
- pH
- Abrasion level
- Installation position
- Discharge arrangement
- Motor supply
Therefore, engineers should select the Toyo VH Slurry Pumps from model-specific hydraulic curves and dimensional data. Otherwise, an unsuitable model may experience excessive wear, insufficient flow or motor overload.
