Product Overview
Maintaining uninterrupted hydraulic circulation is the absolute foundation of successful commercial wastewater evacuation networks. Delivering tremendous extraction capabilities, the Grundfos SE1.80.100.55.4.50B.B is a highly reliable non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water and unscreened raw sewage.
Unmatched thermodynamic stability across the primary internal volute is governed by the revolutionary S-TUBE impeller layout, powerfully propelling heavy media seamlessly without the risk of structural jamming. This advanced hydraulic engine actively prevents microscopic internal pressure warping, safely escorting immense fluid volumes through the extraction corridor without unnecessary internal energy loss.
Supported by a meticulously calibrated 5.5 kW power plant securely wired to a strict 3-phase 415v electrical infrastructure, the heavy-duty unit produces an outstanding maximum head of approximately 18.8 m. Simultaneously, it effectively manages an approximate maximum fluid flow metric of 3432 L/Min, rapidly shifting liquid smoothly between its wide-aperture 100 mm connection flanged ports.
Recognizing the highly critical nature of continuous facility uptime, engineering teams integrated a fully liquidless, maintenance-free cooling network perfectly designed for versatile dry or submerged deep-pit deployments. A highly intuitive stainless-steel clamp assembling framework guarantees that on-site technicians can swiftly detach the primary motor to gain rapid component access during overhauls.
