Product Features
1.Large flow rate and high hydraulic efficiency.
2.Split-case design simplifies inspection and maintenance; pump casing service life ≥30 years, max casing pressure up to 10MPa.
3.Inlet & outlet orientation customizable as required.
4.Wetted parts optional cast iron, cast steel or stainless steel (SS304/SS410); packing seal and mechanical seal are both available.
5.Symmetrical double-suction impeller balances most axial thrust; residual axial load absorbed by end bearings, grease-lubricated bearing arrangement ensures stable running.
Main Application
Widely used for water supply & drainage in power plants, mines, urban construction and coal industry, plus farmland irrigation, flood drainage and various hydraulic projects.
