Slurry Pumps
Heavy-Duty Slurry Pumps Built for Demanding Applications
Designed with a modular construction and multiple shaft sealing options, the AH/AHR range simplifies maintenance while reducing downtime and operating costs. These pumps are widely used throughout the mining, mineral processing, aggregate, dredging and industrial sectors where dependable slurry handling is essential.
Advantages of the AH/AHR Heavy Duty Slurry Pump
Every operation has unique requirements. That’s why SMI provides dependable slurry pumping solutions designed to maximise efficiency, minimise maintenance and deliver long-term performance.
Multiple Shaft Sealing Options
Different applications require different sealing solutions. The AH/AHR range is available with:
- Expeller Seal
- Gland Seal
- Mechanical Seal
We also supply a comprehensive range of replacement wear parts and sealing components to support ongoing maintenance and maximise equipment lifespan.
Superior Wear Resistance
Manufactured using premium high chrome alloys and abrasion-resistant rubber materials, these pumps are built to withstand aggressive slurries and harsh operating conditions while maintaining excellent service life.
Efficient Hydraulic Performance
Optimised hydraulic passages and impeller designs deliver improved flow rates and head performance while reducing energy consumption and increasing pumping efficiency.
Modular Design
The modular construction allows individual components to be replaced independently, making servicing faster, simplifying maintenance and reducing overall operating costs.
High Reliability
Built for continuous heavy-duty operation, the AH/AHR range offers outstanding structural strength and dependable performance in high-impact, high-wear applications, helping minimise unexpected downtime.
Superior Wear Resistance
Optimized design of flow channels and impellers dramatically increases flow and head, reduces energy consumption and improves conveying efficiency.
Efficient Hydraulic Performance
We have accumulated extensive knowledge about the quality standards as well as market needs of thesecountries.
Modular Structure Design
Simple structure, convenient disassembly and assembly, independent replacement of each component, easy repair and maintenance, effectively reducing operation and maintenance costs.
High Reliability
Designed with rugged structure and stable operation, it can operate reliably under high load and high impact working environment for a long time and reduce downtime.
Construction
Pump Construction & Exploded View
Constructed using high chrome alloy or wear-resistant rubber materials, these pumps are ideal for abrasive slurry applications throughout mining, mineral processing, aggregate handling and dredging operations.
To support long-term operation, SMI also supplies a complete range of replacement pump components, including impellers, liners, throatbushes, shaft sleeves and other critical wear parts.
Bearing Assembly
- Function: Supports the pump shaft to ensure smooth rotation while reducing friction and vibration.
- Features: Adopts high-quality bearings for stable operation and long service life.
Base
- Function: Supports the volute liner and its components and holds the pump in place.
- Material: High strength cast iron or steel.
- Features: Robust and durable, easy to install and maintain.
Impeller
- Function: Impeller is the core component of slurry pump, responsible for converting mechanical energy into kinetic energy of liquid and pushing the slurry to flow.
- Material: High chrome alloy, wear-resistant rubber, polyurethane, etc., can be selected according to the working conditions.
- Features: Optimized vane design improves conveying efficiency while reducing energy consumption and wear.
Liners
Includes Front Liner and Back Liner.
- Function: Protect the pump casing from slurry abrasion and assist in flow channel optimization.
- Material: High-chrome alloy or wear-resistant rubber.
- Characteristics: Easy to replace, wear-resistant, can significantly extend the life of the pump body.
Stuffing Box
- Function: Wrap the flow channel, protect the internal components, and guide the flow of the slurry.
- Material: High chromium alloy or rubber, with high wear resistance.
- Features: Thick-walled structural design, which can effectively cope with high-concentration and high-abrasion conditions.
Pump Shaft
- Function: Connects impeller and drive unit, transmits power.
- Material: High-strength alloy steel, heat-treated to improve strength and corrosion resistance.
- Characteristics: Stable structure, smooth operation, avoid bending and breaking.
Shaft Seals
Seals includes Packing Seal, Mechanical Seal, and Expeller Seal.
- Function: Prevent slurry from leaking out of the pump, protect bearings and volute liner.
- Features: A variety of seal forms are available to suit different working conditions.
Expeller
- Function: In the secondary expeller seal, the secondary expeller utilizes centrifugal force to reduce the pressure of the slurry on the sealing area and prevent leakage.
- Material: Cast iron or high chrome alloy.
Features: No need for external water seal, effectively reducing maintenance costs.
Shaft Sleeve
- Function: Protect the pump shaft and reduce the wear of slurry on the pump shaft.
- Material: Various types of stainless steels or steel coated with ceramics.
- Features: Easy to replace, reduce pump shaft maintenance cost.
Volute
- Function: Convert the kinetic energy of the impeller into pressure energy and direct the flow of slurry to the outlet.
- Material: High chrome alloy or wear-resistant rubber.
- Characteristics: Thick wall design, excellent wear resistance.
Discharge Flange
- Function: Connects the pump with the delivery pipe to ensure the smooth delivery of fluids.
- Material: High strength metal.
- Features: Available in different standards such as ANSI/ASME, DIN, etc., to meet customers' different requirements.
Pump Casing
- Function: Secures the liners and pump casing, providing protection for internal components.
- Material: Grey or ductile Iron.
- Features: Robust and easy to install.
