Main features and parameter structure design: The pump body and cover are equipped with replaceable linings (impellers, sleeves, guard plates, etc.), and the discharge outlet can be rotated at 45° intervals for 8 different angles to adapt to different working conditions. The bearing assembly is cylindrical and supports grease lubrication and overall disassembly and maintenance. Performance range: Diameter 25mm-400mm, flow rate 12-5040m³/h, head 5-68m; It is applicable to industries such as metallurgy, mining and power, and can convey solid-liquid mixtures with a temperature not exceeding 80℃ and a mass concentration up to 60%. Shaft seal form: Optional packing seal, auxiliary impeller seal or mechanical seal. The transmission methods include V-belts, elastic couplings, gear reducers, etc. Applicable medium: Highly abrasive slurries (such as concentrate, tailings, slag, coal slag) or corrosive slurries. The back blade design reduces leakage and extends service life
