Industrial wastewater facilities demand resilient pumping infrastructure to maintain fluid transfer under extreme environmental conditions. The Grundfos SE1.50.65.22.A.Ex.2.50D.B operates as an elite non-self-priming, single-stage, centrifugal pump strictly configured for handling wastewater, process water, and unscreened raw sewage safely.
Within the internal hydraulic pathway, the revolutionary S-TUBE impeller provides unparalleled fluid acceleration and guarantees the free spherical passage of suspended solids without risking clogs. This unyielding metallurgical geometry deflects violent physical shocks commonly experienced during rapid flow state changes in deep commercial collection pits.
Driven by a calibrated 2.2 kW power plant wired directly to a 3-phase 415v electrical network, the mechanism effortlessly shifts immense fluid volumes. Operating seamlessly, it achieves a maximum flow of approximately 1248 L/Min alongside an outstanding maximum head of approximately 17.2 m through its precision 65 mm inlet and exhaust port pathways.
Maintaining thermal equilibrium is handled by an innovative liquidless maintenance-free cooling layout, enabling continuous deployment in submerged or dry spaces. An intuitive stainless-steel clamp assembling framework ensures the motor assembly can be rapidly detached for necessary visual field inspection without requiring heavy industrial dismantling tools.
