Product Description
Toyo ET Slurry Pumps
The Toyo ET Slurry Pumps provide compact, heavy-duty pumping for dense and abrasive slurries containing settled solids. Their patented shaft-mounted agitator loosens sediment and directs the mixture towards the semi-open impeller. Therefore, the pump can transfer material that may settle around a conventional submersible inlet.
Moreover, the top-discharge design incorporates a full cooling jacket. Consequently, suitable ET pumps can operate fully submerged or partially immersed in narrow industrial installations.
ET Cooling-Jacket Design
Each Toyo ET heavy-duty pump uses a full cooling jacket to control motor temperature. As a result, suitable configurations can continue operating when the surrounding liquid level falls.
In addition, Toyo provides thermal protection as standard. Therefore, a compatible control system can stop the pump if motor temperature exceeds the permitted limit.
Key Features and Benefits
The Toyo ET Slurry Pumps provide:
- Patented shaft-mounted Toyo agitator
- Semi-open slurry impeller
- Compact top-discharge construction
- Full motor cooling jacket
- Partial-immersion capability
- Heavy-duty shaft and bearing arrangement
- Double mechanical seals in an oil bath
- Custom four-pole electric motor
- Motor service factor of 1.25
- High-chrome impeller, wear plate and agitator

- Alternative metallurgy options
- High-temperature versions available
- Deep-installation versions for selected models
Together, these features support demanding sediment, sludge and abrasive-solids transfer.
Toyo ET Pump Performance
The ET range provides pumping capacities up to 120 m³/h. Moreover, suitable configurations can handle slurry containing up to 55% solids by weight.
Toyo also positions the range for slurry densities of approximately 1.25 kg/dm³ and above.
However, these figures represent overall series capabilities. Therefore, engineers should select each Toyo ET pump from its model-specific hydraulic data and solids-handling limits.
Patented Agitator System
The agitator mounts directly on the pump shaft. During operation, it lifts settled sand, sludge and process residue before the impeller draws the mixture into the casing.
Consequently, the Toyo ET Slurry Pumps can create a more uniform solids concentration around the inlet. Moreover, continuous agitation may reduce manual sump cleaning and sediment removal.
Nevertheless, the agitator cannot process every material. Therefore, users should confirm particle hardness, shape, concentration and maximum size before selection.
High-Chrome Wear 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 resistance to abrasion from sand, minerals and industrial sediment. Moreover, Toyo offers selected ET configurations in alternative metallurgies, including stainless steel.
However, engineers should review the complete slurry chemistry before choosing construction materials.
Adjustable Wear Plate
The Toyo ET design includes an adjustable wear plate. Therefore, technicians can restore the clearance between the impeller and wear surface as gradual abrasion occurs.
Consequently, regular adjustment helps maintain hydraulic efficiency and pumping capacity. In addition, facilities may extend wear-part life before major component replacement becomes necessary.
Motor, Shaft and Seal Protection
The Toyo ET Slurry Pumps use a custom four-pole motor with a 1.25 service factor. Therefore, the motor can accommodate changing loads during dense-slurry transfer.
Meanwhile, a heavy-duty shaft and carefully selected bearings support the rotating assembly. Two mechanical seals operate inside an oil bath. Consequently, the sealing system helps protect the motor from abrasive slurry.
Operating Range
Published ET Series limits include:
- Maximum capacity: Up to 120 m³/h
- Solids concentration: Up to 55% by weight
- Particle size: Up to 30 mm
- Standard slurry temperature: Up to 60°C
- High-temperature version: Up to 80°C
- Permitted pH range: 4–14
- Standard operating depth: Up to 30 m
However, these limits do not apply simultaneously to every configuration. Therefore, users should confirm the selected model’s individual specifications.
Deep-Installation Versions
Standard ET pumps operate at depths up to 30 metres. Alternatively, special ET10 to ET20 versions can operate at depths up to 60 metres without an additional external device.
Consequently, these configurations may suit deep pits, shafts and submerged industrial applications.
However, cable length, pressure requirements and pump construction must match the required operating depth.
Toyo ET Applications in India
The Toyo ET Slurry Pumps may support applications across India such as:
- Narrow industrial sumps
- Construction pits containing sediment
- Sand and slurry transfer
- Tank and lagoon cleaning
- Mining and mineral-processing slurry
- Quarry water containing solids
- Settling-basin clean-out
- Abrasive sludge pumping
- Foundation and piling work
- Process-residue transfer
- Dredging support
- Partially immersed pumping duties
Moreover, the compact top-discharge design suits confined installations where available space is limited. Nevertheless, engineers should review the required head, abrasion level, solids concentration and particle dimensions before final selection.
Selecting the Correct Toyo ET Pump
Correct selection depends on:
- Required flow and total head
- Slurry density
- Solids concentration
- Maximum particle size
- Slurry temperature
- pH
- Operating depth
- Construction material
- Motor supply
- Installation arrangement
Therefore, engineers should select the Toyo ET Slurry Pumps from model-specific hydraulic curves and technical data. Otherwise, an unsuitable configuration may experience excessive wear, reduced flow or motor overload.
