Grundfos SE1.50.80.40.2.50B.B Cast Iron 3" Submersible Drainage Pump for Heavy Waste with S-TUBE Impeller

Commercial wastewater extraction loops and extreme pit environments impose severe mechanical stress on transfer machinery. Operating flawlessly under these demanding parameters, the Grundfos SE1.50.80.40.2.50B.B functions as a non-self-priming, single-stage centrifugal pump configured strictly for handling raw sewage and volatile process water.

The uncompromisingly rigid external framework of this mechanism acts as an impenetrable containment vessel against abrasive liquid contaminants. Deflecting the violent physical shocks associated with rapid internal pressure changes, the dense metallurgical housing prevents microscopic warping, securing the exact critical alignment of the rotational assembly.

Hydrodynamic stability within the internal volute is expertly achieved utilizing the advanced S-TUBE impeller geometry, accelerating dense media seamlessly without structural jamming. Powered by an energetic 4 kW drive directly wired to a 3-phase 415v network, the unit achieves an impressive maximum head of approximately 25.1 m and shifts an approximate maximum flow of 1164 L/Min.

Eliminating the requirement for active on-site technician supervision, a sophisticated liquidless maintenance-free cooling network regulates core temperature for safe continuous submerged or completely dry deployments. An intuitive stainless-steel clamp assembling framework ensures the entire primary motor unit can be rapidly detached for necessary field inspection without complex industrial toolsets.
