Recomendaciones de selección
1.Corrosive filtrate:Fully lined with fluorine or 316L stainless steel is preferred.
2. Containing hard particles: Wear- resistant impellers (such as tungsten carbide coating) are required.
3. Maintenance tips:
Check the wear of mechanical seals every month. If the pump is not used for a long time, the liquid in the pump must be drained
to prevent crystallization. If a performance curve (QH) or material corrosion resistance test report is required, please specify the specific medium composition (such as Cl concentration, solid content, etc.).
