AH Type Single-suction Slurry Pump

The AH type slurry pump (sometimes referred to together with M and HH types) is a heavy-duty centrifugal pump. Its pump body and pump cover are equipped with replaceable metal liners (the material is mostly high-chromium wear-resistant alloy), and the liners can be used until they are worn through, in order to extend the maintenance period. . This series of pumps offers a wide range of performance: the flow rate varies from 7.1 m³/h to 5000 m³/h, the head range is from 4.8m to 68m, and the outlet diameter is from 25mm to 500mm. The outlet direction of the pump can be rotated at intervals of 45° to eight different positions for installation, meeting various requirements for pipe layout.

Heavy-duty durable structure: The pump body adopts a double pump shell design. The pressure-bearing layer (outer shell) and the wear-resistant layer (inner liner) are separated. The flow components (impeller, sleeve, and guard plate) are made of high-chromium wear-resistant alloy or rubber, which is resistant to wear and corrosion. . It has thick wear-resistant components and is equipped with heavy-duty brackets. The bearing assembly adopts a cylindrical structure, with high shaft rigidity and capable of withstanding harsh working conditions. .
Efficient and flexible design: The impeller adopts a wide flow channel and concave blades, which enhance the flow capacity and anti-corrosion performance. The efficiency of the high-efficiency impeller can reach up to 85%. . The transmission methods are diverse, including direct connection (DC), V-type belt (CL, CV, CR, ZL, ZV, ZR), gear reduction box, hydraulic coupling, and variable frequency drive, among others. .
Reliable seals and bearings: The shaft seal offers three types of sealing solutions: packing seal, auxiliary impeller seal, and mechanical seal, to meet the sealing requirements of various working conditions. . The bearings are equipped with heavy-duty single-row or double-row tapered roller bearings and cylindrical roller bearings. They are lubricated with thin oil or grease and can withstand high radial and axial loads. They have a long service life. .
Widely adaptable: Suitable for conveying highly abrasive and high-concentration slurry, or low-concentration but high-head slurry. Within the maximum allowable working pressure range of the pump, it can be used in multiple stages in series to meet the requirements of long-distance transportation.

Mining and Mineral Processing
Concentrate and Tailings Transportation: Used in beneficiation plants for iron ore, copper ore, gold ore, lead-zinc ore, etc., for transporting 40%-65% concentrated ore slurry or for long-distance tailings discharge.
Grinding and Classification Circuit: As the discharge pump for ball mills or semi-autogenous mills, or providing high-pressure feed to hydrocyclones.
2. Electric Power Industry
Hydraulic Ash and Slag Removal: For coal-fired power plants, transporting bottom ash and fly ash (powdered coal ash).
Flue Gas Desulfurization System: Transporting limestone slurry or gypsum slurry. Aged rubber-lined type (AHR) can be selected when sensitive to acidic media.
3. Metallurgy and Steel Industry
Alumina Production: Transporting strong alkaline and highly abrasive bauxite slurry and red mud.
Steel Plant Flocculation Water: Transporting iron oxide scale water and dust removal sludge from the cyclone wells.
Nonferrous Metallurgy: Transporting leaching residues and slurry in the wet smelting processes of copper, lead, zinc, etc. .
4. Coal Industry
Coal washing: Used for the circulation of magnetic iron ore powder suspension in heavy medium coal separation, as well as the transportation of coarse coal slime.
