This series of submerged pumps features a maximum submerged depth of 3.6 meters and adopts Jiahe’s patented dual-support structure. Above the liquid level, two rows of angular contact ball bearings withstand axial loads; below the liquid level, one or two pairs of sliding bearings (shaft sleeves and bushings) bear radial loads, ensuring stable and vibration-resistant operation of the entire unit.
The flow-through components are precision-cast from Jiahe’s proprietary high-quality JSB special alloy, which delivers excellent corrosion resistance to high-temperature concentrated sulfuric acid, greatly extending service life and enabling long-term stable operation in sulfuric acid applications.
