LS Vertical Centrifugal Pump

The LS vertical centrifugal pump is designed based on the performance parameters of IS centrifugal pumps, with scientific optimization improvements referencing structural features of other vertical pumps. It complies with China's Machinery Industry Standard JB/T53058-93. The LS series serves as a successor to IS centrifugal pumps, DL multi-stage pumps, ISG vertical centrifugal pumps, and SG pipeline pumps. Additionally, our company offers specialized variants—LSR hot water pumps, LSH chemical pumps, LSY oil pumps, and LSG high-temperature pumps—with identical parameters to replace conventional centrifugal pumps across all applications.

Model Designation

1、Optimized Design: Rational structure, compact size, and aesthetically pleasing appearance. The structural center of gravity aligns with the pump base center, enhancing operational stability and service life.

2、Easy Installation: Identical inlet and outlet diameters aligned on the same axis allow installation like a valve at any pipeline location.

3、Direct-Coupled Structure: High-concentricity direct connection between motor and impeller ensures vibration-free operation and low noise levels.

4、Leakage-Free Sealing: Mechanical seals constructed with wear-resistant materials (carbide and silicon carbide) eliminate leakage issues common in packed seals, extending service life and maintaining a clean, tidy operating environment.

5、Cost Savings: Unique installation design reduces pump room floor space and spatial requirements by 40–60%, lowering infrastructure investment costs.
