Focusing on stainless steel water pumps
The national standard flange WQ-S all-stainless steel precision cast sewage submersible pump adopts a stainless steel precision cast casing, which has the characteristics of corrosion resistance, environmental protection, high head, and large flow.
1. The oil chamber adopts fluorine rubber double-end mechanical seals, while the outer chamber adopts a single-end fluorine rubber mechanical oil seal structure, effectively reducing the problem of water ingress caused by shaft wear due to friction between sand and the shaft.
2. The motor adopts vacuum impregnation to achieve Class F insulation and is equipped with a thermal protection device, effectively extending the pump's service life.
3. According to customer requirements, a stirring device can be added. This device generates strong stirring force as the motor shaft rotates, turning sediment in the sewage tank into suspended matter before discharge. A cutting device can also be included, which can shred long fibers, plastics, paper bags, straw, and other debris in the sewage before discharge.
It's suitable for building construction, hospitals, residential areas, municipal engineering, road traffic and construction, chemical plating, factory sewage, aquaculture, pharmacy, beverages, seawater and brine, solid particles contained in general corrosive media, long fiber wastewater, sewage.
1. The submerged depth from the center of the impeller should not exceed 5m;
2. The temperature of the conveying medium should not be higher than +40℃;
3. The PH value of the conveying medium is 304 (4-10) and 316 (2-13);
4. The kinematic viscosity of the conveying medium is 7x10-7-23x10-6m2/s.
