Consistent fluid extraction in demanding environments requires resilient, highly capable hardware. Evaluated as a heavy duty, submersible stainless steel grey water pump, the Grundfos UNILIFT AP12.40.06.3 safely relocates non-aggressive liquids. Operating across three-phase industrial networks, the unit functions optimally as a permanent installation or as a portable asset for clearing clean and storm water from work sites.
Power delivery is heavily optimized to maintain robust displacement during continuous shifts. Connected to a 3 x 415 V supply, the 0.6 kW core operates smoothly with a rated draw of just 1.6 Amps. The internal volute forcefully pushes a 300 L/Min maximum flow through a 40 mm female connection. Countering steep pipeline gravity, the pressure reliably secures a 13 metre maximum head.
Managing heavily clouded run-off relies on an unrestrictive internal design that inherently rejects clogs. A durable semi-open stainless steel impeller securely handles the primary vortex, safely passing solid environmental debris up to 12 mm. This expanded tolerance allows the manual pump to aggressively agitate standing liquids, extracting fluid down to a strict 100 mm minimum pumping clearance.
Deep submersion is fully supported by an IP68 rating, guaranteeing safe underwater placement down to 7 metres. An intelligent motor cooling jacket surrounds the core, allowing the unit to efficiently dissipate heat and operate safely during long partial submersion periods. Fabricated from 304 stainless steel, it comfortably processes pH 4 to 10 liquids alongside 55°C temperature thresholds.
