Managing sudden fluid accumulation across commercial sumps requires dependable automated systems. Categorized as a heavy duty, submersible stainless steel grey water pump, the Grundfos UNILIFT AP12.40.06.A3 actively maintains dry conditions. Triggered automatically by rising fluid levels, this three-phase unit efficiently clears clean water, storm water, and slightly dirty run-off from permanent installations.
Stable industrial power allocation ensures immediate and forceful hydraulic action upon start-up. Wired into a 3 x 415 V grid, the highly efficient 0.6 kW motor sustains a strict 1.6 Amps rated current. The system creates a powerful 300 L/Min maximum flow output from the 40 mm female discharge port, easily overcoming vertical resistance to achieve a 13 metre maximum head.
Internal mechanical reliability is heavily dictated by the geometry of the fluid transit path. A precision-balanced semi-open stainless steel impeller expertly controls the central circulation, allowing solid 12 mm particles to successfully pass through the volute. This physical clearance restricts abrasive damage to the core components and safely draws the liquid down to a 100 mm minimum depth.
An IP68 structural classification guarantees that the motor remains entirely protected at installation depths up to 7 metres. An integrated liquid cooling jacket continuously dissipates operating heat, allowing the automated system to securely pump while only partially submerged. It safely manages 55°C environmental fluids and processes wastewater spanning a pH range from 4 to 10.
