Zidong ZH metal liner slurry pump is special designed for convey water and solid mixture medium. The ZH slurry pump is a single-stage, single-suction and horizontal heavy duty centrifugal slurry pump with a cantilever design.
Parts in contacting with the medium are made of latest wear-resistance 27% chrome alloy white iron with hardness 62HRC over, which has an excellent feature for maximum resistance to strong abrasive, coarse particle.
Designed for continuous conveying highly abrasive,high-hardness, high-concentration, low-corrosion slurry contain suspended solid particles, such as finished ores, refuse ores, ashes, cinders, cements, mud, mineral stones in the tailing mining,minerals recycling ,coal washing, industries of metallurgy, pulp and paper manufacture , power plant, building material,&chemical engineering, sand dredging etc.
A centrifugal slurry pump is mainly composed of 3 parts:
1. The wetted parts (such as impeller, volute ,throatbush,FPL insert)
2. Shaft seal parts(such as gland packing seal, expeller seal or dynamic seal,etc.)
3. Bearing assembly parts,etc.
Bearing Assembly: A large diameter shaft with short overhang minimizes deflection and contributes to long bearing life.Only four through bolts are required to hold the cartridge type housing in the frame.
