Product Overview
Highlighting an advanced primary structural material choice and dense casting geometry, the Grundfos SEG.40.31.EX.2.50B delivers tremendous subterranean resilience. Grundfos SEG pumps are specifically designed for pressurized pumping of wastewater with discharge from toilets. Constructed from high-strength components, it aggressively excels in restrictive fluid environments.
Deep at the mechanical core, this industrial pump features an aggressive grinder system that destructs dense solids into fine particles, allowing seamless transfer through restricted municipal piping. The external housing surface remains uniformly smooth to prevent foul dirt from physically adhering to the bare chassis, extending operational lifespans.
Delivering formidable kinetic force directly into the internal fluid columns, the motor leverages exactly 3.1 kW of robust operational output. Engineered explicitly for commercial three-phase 415v grids, this highly reliable unit achieves a maximum head limit of 37 meters while continuously circulating a maximum flow of 283 L/Min effectively.
Developed with operational safety as a fundamental priority, this pumping solution is equipped with a heavily insulated electrical harness. The specialized power cable incorporates dedicated wires for thermal sensors buried deeply within the main motor winding. This strict arrangement constantly guards against internal temperature spikes.
Features
- Draws exactly 7 Amps of perfectly stable rated current during continuous maximum biological displacement.
- Constructed internally with incredibly dense EN 1561 standard iron for extreme external durability.
- Engineered fully without an integrated starter plug to safely allow complex localized terminal wiring.
- Operates efficiently without requiring internal start capacitors, increasing overall electromechanical resilience.
- Evaluated successfully under demanding ATEX II 2 G Ex db IIB T4/T3 Gb explosion resistance criteria.
- Delivers highly impressive eighty-four percent motor efficiency while fully submerged under maximum liquid strain.
