Horizontal Large Particle Slurry Pump

Horizontal large particle slurry pump is a critical equipment for addressing the challenges of transferring abrasive, high-density, and large-particle slurries in mining and heavy industry, and Milestone's MAH series is a representative heavy-duty solution in this field. The MAH series, designed as horizontal slurry pumps, features a rugged cast iron outer casing with reinforcing ribs, ensuring excellent high-pressure strength and operational safety-key requirements for withstanding the impact of large particles in slurries. It offers replaceable wear liners in 27% chrome white iron, rubber, or urethane, allowing precise adaptation to different slurry types (such as highly abrasive or viscous slurries) and particle sizes. With discharge sizes ranging from 1 inch (25mm) to 18 inches (450mm), flow rates covering 10.8 to 6500 m³/hour (48-28600 USGPM), and maximum heads up to 125 meters (410ft) for high-head models, the series fully meets the heavy-duty transfer needs of harsh industrial environments.

The MAH series also excels in performance optimization and maintenance convenience, which are essential for the stable operation of slurry transfer systems. Its impeller is equipped with pumpout vanes on the rear face to prevent slurry recirculation, reducing impeller wear and maintaining efficient fluid transfer. An external impeller adjustment bolt, easily accessible under the bearing assembly, enables quick adjustments to impeller clearance without disassembling the front cover plate, pipework, or bearing assembly-this design minimizes downtime and simplifies routine maintenance. Additionally, the pumps adopt heavy-duty bearing assemblies (angular contact bearings in the wet end, deep groove roller bearings in the drive end) with grease lubrication as standard and optional oil lubrication, along with flexible shaft sealing options (packed gland, mechanical seal) and a standard expeller to reduce seal face pressure. These thoughtful designs ensure long-term reliable operation even under continuous heavy loads, making the MAH series a dependable Horizontal large particle slurry pump for industrial sites.

To further adapt to diverse application scenarios, the MAH series provides a rich range of models, including metal-lined, rubber-lined, and high-head variants, each tailored to specific working conditions. Metal-lined models (e.g., MAH 2x1.5 Metal Liner) use 27% chrome white iron for liners and impellers, ideal for highly abrasive large-particle slurries; rubber-lined models (e.g., MAH 3x2 Rubber Liner) are suitable for scenarios requiring gentler slurry handling; high-head models like MHH 6x4 FHH can deliver heads up to 125 meters, meeting high-lift transfer demands. All spare parts of the MAH series are fully interchangeable with common mining slurry pump footprints, enabling users to upgrade existing systems easily. Combined with high-quality materials such as 4140 high-tensile steel shafts and 420 stainless steel shaft sleeves, the MAH series delivers durability and efficiency, solidifying its status as a trusted Horizontal large particle slurry pump.
