[0002] Horizontal slurry pumps are suitable for industries such as mining, metallurgy, electricity, coal, petroleum, chemical industry, transportation, river dredging, building materials and municipal engineering. Heavy-duty slurry pumps have thicker wear parts and are equipped with heavy-duty brackets, so they can transport corrosive and abrasive slurries containing solid particles, such as ash and coal slurry transportation in power plants, ore slurry transportation in metallurgical ore dressing plants, coal washing slurry and heavy medium transportation in coal washing plants, etc.
