Product Description
WQP SS316 Submersible Sewage Pump for Sewage, Sludge, and Dewatering – Industrial & Municipal Applications
In demanding industrial and municipal wastewater treatment environments, reliability, corrosion resistance, and high solids handling capabilities are paramount. The WQP SS316 Submersible Sewage Pump distinguishes itself with superior performance, designed specifically as a high-end solution for the rigorous challenges of sewage, sludge, and dewatering applications. Constructed with 316 Stainless Steel (SS316) wet parts, this pump offers exceptional durability, chemical resistance, and long-term stability, making it the ideal choice for industrial wastewater treatment and municipal sewage systems.
Why Choose the WQP SS316 Submersible Sewage Pump?
1. Superior Corrosion Resistance with 316 Stainless Steel
Unlike standard cast iron or 304 stainless steel models, all fluid-wetted parts of the WQP SS316—including the pump casing, impeller, and shaft—are crafted from marine-grade 316 Stainless Steel. This material effectively resists chlorides, acids, alkalis, and other corrosive chemicals common in industrial wastewater, landfill leachate, food processing effluents, and coastal municipal systems. Its recommended pH range surpasses that of SS304 (typically handling pH 2–12 under controlled conditions), ensuring a longer service life even in highly corrosive environments.
2. Optimized for Sludge and High-Solid Media
The WQP SS316 features a large-passage, non-clog hydraulic design capable of efficiently transporting solids with diameters up to 50–70 mm. It easily handles fibrous materials such as rags, hair, and organic debris without clogging. Optional configurations include:
Cutter/Grinder Type: Designed to shred stubborn solids at the intake.
Auto-Agitator Type: Agitates settled sludge prior to pumping—perfect for sumps, septic tanks, and sludge holding tanks.
3. Robust Construction and Advanced Protection
Sealing: Equipped with dual Tungsten Carbide mechanical seals operating in an oil-filled chamber for superior wear resistance and leak prevention.
Motor Safety: Features an IPX8 waterproof rating and Class F insulation to ensure safe submersion and continuous operation.
Smart Protection: Integrated leakage detection sensors and thermal overload protection prevent dry running, overheating, and seal failure.
IoT Integration: An optional Smart IoT Monitoring Module enables remote diagnostics, energy tracking, and predictive maintenance—improving efficiency by over 30% compared to traditional models.
4. Flexible Installation and Maintenance
The WQP SS316 supports two installation methods:
Portable Installation: Via a discharge hose coupling for temporary drainage or emergency scenarios.
Permanent Fixed Installation: Utilizing standard flanges (PN10/PN16) or an Auto-Coupling Guide Rail System, allowing for rapid lifting and maintenance without the need for personnel to enter the wet well.
