NP- HH Slurry pump applications
NP-HH slurry pumps are suitable for pumping slurry with high-hardness, strong-corrosion and high-concentration liquids that contain suspended solid particles, such as finished ores, refuse ores, ashes, cinders, cements, mud, mineral stones and etc. in the industries of metallurgy, mining, coal, power, building material and etc. The temperature of the pumped solid-liquid mixture should be ≤80oC, and the weight concentration should be ≤60. These pumps can also be applied multi-staged in series.
High Head slurry pump advantages
The positions of the NP-HH slurry pump outlet can be positioned at an interval of 45°according to different requirements, so eight different angles can be applied by rotation in installation.
The NP-HH type horizontal slurry pumps have pump bodies (volute liners, front and back liners) that consist of replaceable wear-resistant metal liners or wear-resistant rubber liners, and impellers can also apply wear-resistant metal material or wear-resistant rubber material.
The NP-HH type mining slurry pump only apply wear-resistant metal material as their pump bodies and impellers.
