High-volume fluid optimization relies on the uninterrupted strength of machinery operating under severe environmental stress and constant abrasive loading. Engineered for supreme pit resilience, the Grundfos SE1.50.80.30.2.50B.B is an elite Submersible Drainage Pump designed precisely for handling wastewater, process water, and unscreened raw sewage.
Fortified by a highly durable cast iron foundational casing, this unit entirely deflects the violent physical shocks commonly experienced during rapid flow state changes. Its thick external barrier shields sensitive internal electromechanical elements from continuous exposure to abrasive particles, ensuring the volute geometry remains completely intact.
Thermodynamic stability and fluid velocity are expertly governed by the specialized S-TUBE impeller structure. Powered by a robust 3 kW motor locked to a 3-phase 415v electrical infrastructure, the unit scales to an impressive maximum head of approximately 21.6 m and pushes an approximate maximum flow of 1164 L/Min through its 65 mm and 80 mm pathways.
Eliminating the need for constant supervision, this heavy-duty machine integrates an advanced maintenance-free liquidless cooling network suited for dry or completely submerged deployments. A highly intuitive stainless-steel clamp assembling framework ensures rapid unit disassembly, granting technicians immediate internal component access when required.
Features
- Capable of safely routing internal liquid medium temperatures dynamically ranging between 0 and 40 °C.
- Assembled with a substantial total net structural weight measuring exactly 96 kg to eliminate rotational vibration.
- Provides a massive 12 m maximum installation depth rating specifically tailored for deep commercial collection pits.
- Designed to actively sustain a maximum operating pressure threshold measuring exactly 6 bar under peak loading.
- Implements a premium Class F insulation rating to actively prevent internal electrical component degradation.
- Equipped with an extended 15 m Lyniflex power cable structure to streamline versatile facility grid connections.
- Built around an IP68 standard enclosure specifically optimized for continuous fully submerged field operations.
