Detailed performance data, rotational speed, motor power and material configuration depend on the selected model and actual operating conditions.
The AH pump uses a double-casing structure consisting of a strong outer casing and replaceable internal wet-end components.
This design improves structural reliability while allowing worn internal parts to be replaced without changing the entire pump casing.
The axially split casing design provides convenient access to internal components during inspection and maintenance.
It helps simplify the replacement of liners, impellers and other wear parts, reducing maintenance difficulty and equipment downtime.
The pump is suitable for transporting slurry with a high solids content, including mineral slurry, tailings, coal slurry, ash slurry and construction slurry.
The hydraulic passage is designed to handle liquids containing suspended solid particles under demanding industrial conditions.
Different wet-end materials can be selected according to the abrasiveness and corrosiveness of the pumped medium.
The correct material configuration helps extend service life when handling hard particles, chemically active liquids or combined abrasive-corrosive slurry.
With flow capacities from 12 to 5040 m³/h and heads from 5 to 118 meters, the AH series can be used for small processing systems as well as large-scale slurry transportation projects.
Multiple AH pumps can be connected in series when the required system head exceeds the capacity of a single pump.
Series operation is particularly suitable for long-distance slurry transportation, high-elevation delivery and pipelines with significant resistance.
The discharge outlet can be rotated and installed in eight different positions.
This flexible design allows the pump to adapt to different pipeline directions, plant layouts and site installation requirements.
The split-casing design and replaceable wet-end components provide convenient access for maintenance.
Major wear parts can be inspected and replaced according to actual operating conditions, helping reduce lifecycle costs.
The heavy-duty structure is suitable for continuous industrial operation when the pump is correctly selected, installed and maintained.
The AH Slurry Pump is widely used for mineral processing, ore slurry transportation, mill discharge, cyclone feed, flotation systems, tailings transfer and mine dewatering applications.
It is suitable for transporting abrasive slurry containing mineral particles of different concentrations.
In metallurgical plants, the pump can be used for transporting slag slurry, concentrate slurry, process slurry and wastewater containing solid particles.
It is suitable for demanding production processes that require continuous and reliable slurry transfer.
The AH pump can be applied in thermal power plants for ash handling, bottom-ash transportation, fly-ash slurry transfer and other slurry circulation systems.
Its heavy-duty structure makes it suitable for handling abrasive ash-water mixtures.
Typical applications include coal washing, coal preparation, dense-medium circulation, coal slurry transportation and coal-processing wastewater handling.
The pump can be selected according to the coal-particle size, slurry concentration and required delivery distance.
The pump can be used for transporting sand-water mixtures, construction slurry, foundation-pit slurry, tunneling slurry and other media containing abrasive solids.
The AH series is also suitable for cement plants, sand processing, dredging support systems, industrial wastewater treatment and other heavy-duty slurry transportation projects.
The AH Heavy-Duty Slurry Pump can be used for handling:
The maximum particle size, slurry density, solids concentration, viscosity and corrosiveness should be confirmed during pump selection.
The double-casing structure separates the main pressure-containing casing from the internal components that are directly exposed to the slurry.
This configuration provides several advantages:
The internal liners and impeller can be selected according to the actual characteristics of the slurry.
A single slurry pump may not provide sufficient head for long pipelines, large elevation differences or high-resistance transportation systems.
In these situations, multiple AH pumps can be connected in series. Each pump increases the total pressure available to overcome pipeline resistance and elevation requirements.
Multistage series systems may be used for:
When designing a series pumping system, the pressure rating of the pump casing, pipelines, valves and fittings must be considered.
The AH pump discharge can be arranged in eight different installation positions.
This feature allows the outlet direction to be adjusted according to the pipeline route and site layout without significantly changing the overall pump installation.
Flexible outlet orientation can help:
The required discharge direction should be confirmed before manufacturing or installation.
The correct wet-end material is important for pump service life and operating reliability.
High-chrome alloy is commonly selected for highly abrasive slurry containing hard mineral particles.
It is suitable for mining, mineral processing, ash handling and sand transportation applications where wear resistance is the primary requirement.
Corrosion-resistant materials may be selected for chemically active slurry or liquids containing corrosive components.
The final material selection should be based on the medium composition, pH value, chloride content, temperature, particle hardness and solids concentration.
For certain fine-particle slurry or corrosive media, an elastomer-lined configuration may be considered when compatible with the operating temperature and slurry characteristics.
Material availability and suitability should be confirmed according to the selected pump model.
The pump should be installed on a strong and level foundation capable of supporting the pump, drive unit and pipeline loads.
The suction pipeline should be as short and direct as possible. Unnecessary bends and restrictions should be avoided to reduce suction losses.
The inlet pipeline diameter should be suitable for the required flow rate and slurry velocity.
The suction and discharge pipelines must be independently supported so that their weight is not transferred to the pump casing.
Before startup, the pump and suction line should be correctly prepared according to the selected installation and priming method.
The pump should not operate without slurry or flushing liquid when dry running may damage the shaft seal or wet-end components.
For series operation, the pressure at each pump stage and the total pipeline pressure must remain within the allowable ratings of the equipment.
Regular inspection and planned replacement of wear parts are essential when pumping abrasive slurry.
Maintenance checks should include:
Operating the pump close to its recommended duty point can help reduce excessive wear, vibration and energy consumption.
The AH Heavy-Duty Slurry Pump combines a wide performance range, robust double-casing construction and flexible installation options.
Its replaceable wet-end components are designed for slurry containing high concentrations of abrasive or corrosive solids. Multiple pumps can be connected in series for high-head and long-distance transportation systems.
The eight-position discharge design allows the pump to adapt to different pipeline layouts, while the axially split casing provides convenient access for maintenance.
With flow capacities up to 5040 m³/h and heads up to 118 meters, the AH series provides a reliable solution for mining, metallurgy, coal processing, power generation and construction slurry applications.
