Description du produit

Polymer concrete pump stations are used for sponge city construction, water environment governance, and urban sewage and rainwater lifting; the matched submersible screw centrifugal pump has excellent non-clogging performance, capable of conveying sewage containing solid particles, long fibers, and sludge, with solid content conveying capacity much higher than ordinary impeller centrifugal pumps; the sunken structure is suitable for installation methods with limited on-site excavation conditions (natural slope excavation, steel sheet pile support excavation, caisson-type support excavation are all acceptable).
