Heavy-duty single-stage, single-suction centrifugal pump engineered for corrosive media transfer and circulation in industrial processes. The pump combines a metal pressure-bearing shell with a non-metallic fluoroplastic lining (PTFE/F46, PVDF, PP) using a sintered “tortoiseshell” mesh lining process to deliver high corrosion and chemical resistance while maintaining mechanical strength.
Key features:
- Metal shell lined with fluoroplastics (PTFE/F46, PVDF, PP) for pressure resistance plus chemical compatibility
- Impeller, pump cover and shaft sleeve: metal inserts fully wrapped with fluoroplastic and sintered/pressed as a single assembly
- Externally mounted mechanical shaft seal for robust, serviceable sealing performance
- Inlet/outlet reinforced with cast steel to improve pressure resistance and installation strength
- Flow range: 3–300 m3/h
- Operating temperature range: -20 to 110 °C
Performance and benefits:
- Excellent corrosion resistance to strong acids, alkalis, oxidants, organic solvents and reducing agents — suitable for long-term handling of highly corrosive media
- Improved anti-fall and anti-cracking lining compared with similarly lined pumps
- High mechanical strength, stable running and reliable sealing for continuous industrial service
- Good creep resistance, thermal deformation resistance and aging resistance for extended service life
- Designed for straightforward disassembly and maintenance to minimize downtime
Typical applications:
Suitable for chemical processing, nonferrous metal smelting (electrolyte transfer), electroplating, pharmaceuticals, petroleum, dyes, pesticides, paper making, food and textile processing, titanium dioxide production, salt chemicals, potassium compound fertilizers and other industries requiring corrosion-resistant liquid transfer. Commonly used to handle sulfuric, hydrochloric, hydrofluoric, nitric acids, aqua regia, concentrated alkalis, strong oxidants and aggressive organic solvents.
