WYTSFB
Head Range:3-30 m Motor Power:0.25-3 kw Inlet/Outlet Range:DN25-DN50 SFB type Stainless Steel Corrosion-resistant Centrifugal Pump
Head Range:3-30 m
Motor Power:0.25-3 kw
Inlet/Outlet Range:DN25-DN50
Structural Features
- All stainless steel body structure
Pump body, impeller, shaft sleeve and other overflow parts are made of 304/316L stainless steel whole casting, no welding seams, to avoid the risk of intergranular corrosion—a critical feature for corrosive sludge pump applications requiring long-term durability.
- Double end face mechanical seal system
Standard assembled double end face mechanical seal, support external flushing liquid, effectively isolate corrosive medium leakage.
Closed impeller design
The overflow parts (impeller, pump casing) are made of high chrome cast iron, which is wear-resistant and corrosion-resistant, and is suitable for sewage environments containing solid particles.
Vortex/Cutter Impeller Options
Precision casting closed impeller, dynamic balance level up to G6.3, to ensure low vibration, high stability operation.
Product Advantages
Excellent corrosion resistance
The 316L material can withstand acid and alkali solutions of pH 3~11, organic solvents and weakly oxidizing media (e.g. nitric acid ≤20%).
Long life sealing program
Designed for a corrosive sludge pump build, this dual seal configuration + flushing system delivers life expectancy increased by 200% compared to single seal, with leakage rate <5ppm (in accordance with API 682 standard).
High efficiency and energy saving operation
Optimized design of hydraulic model, efficiency 8~12% higher than ordinary centrifugal pump, standard with IE3 high efficiency motor.
Convenient maintenance
Rear-opening structure, seals and bearings can be replaced without disassembling pipelines, reducing maintenance time by 60%—a significant upgrade in service efficiency for corrosion resistant pumps, especially in a demanding corrosive sludge pump application where minimizing downtime is critical.
Application Scenarios
Chemical Process Conveying
Acid/alkali circulation (e.g. sulfuric acid, sodium hydroxide), solvent transfer (methanol, acetone), temperature range -20℃~120℃.
- Surface treatment industry
- Environmental protection and water treatment
Wastewater dosing system (PAC, sodium hypochlorite), membrane filtration high-pressure flushing, seawater desalination pretreatment.
Service Assurance
- Accurate demand matching
Free on-site demand analysis, customized flow, pressure and piping configuration scheme;
