1'' 3'' High Head Slurry Pumps
Naipu® NHH series were designed to produce high heads per stage at high pressures. commonly used for long distance transport lines, the NP-HH lines can often satisfy application duties with a single pump where others require multiple pumps.the range is capable of handling medium size particles and pumping at heads in excess of 90 meters per stage.

Pump Model Selection of NHH Pump
When the type selection is conducted, the performance curve table for clear water of a pump shall be referred to, and the coefficient of range for the flow selected is as follows:
-- For slurry of medium density and strong abrasiveness, the coefficient of flow range will be 40-80%;
-- For slurry of low density and strong abrasiveness, the coefficient of flow range will be 40-100%;
-- For the highest efficiency point under a certain RPM condition, its corresponding flow rate will be 100%.
