What materials are suitable for screw pump stator & rotor for Sewage sludge /Wastewater ?
The material selection of screw pump stator and rotor must match the conveyed medium properties, solid content, temperature and corrosiveness, following the core principle of “stator resists medium corrosion/wear, rotor resists erosion/corrosion”. The specific selection steps are as follows: 1. Clarify Medium & Working Condition Parameters First confirm 3 core indicators: medium type (slurry/crude oil/chemical slurry, […]
