Establishing an autonomous fluid transfer system is critical for safeguarding property against unexpected accumulation. Recognized as a heavy duty, submersible stainless steel grey water pump, the Grundfos UNILIFT AP12.40.08.A1 provides consistent automatic clearance. It is tailored for permanent installations requiring rapid evacuation of clean water, storm water, and slightly dirty wastewater across domestic and light industrial sites.
Precision power allocation ensures large volumes are shifted instantly upon float switch activation. Powered by a 1 x 240 V input, the 0.8 kW drive reliably demands 5.9 Amps during full load operation. The internal hydraulic structure aggressively channels a maximum flow of 350 L/Min through a 40 mm female outlet. Countering immense vertical pipeline resistance, the automated system achieves a 15 metre maximum head.
Operating within unpredictable underground environments requires robust solids handling. A meticulously balanced semi-open stainless steel impeller forcefully drives the primary vortex, stripping away settled sediment. By maintaining wide internal clearances, the chamber safely permits the transit of 12 mm solid matter to severely limit internal jamming, while drawing the liquid down to a 100 mm minimum depth.
Engineered with an IP68 classification, the completely sealed motor withstands submerged environments down to a 7-metre depth. A built-in cooling jacket regulates internal thermals to facilitate extended pumping during partial liquid exposure. Constructed entirely from 304 stainless steel, it processes 55°C continuous liquids (peaking at 70°C for two minutes) and accommodates ambient fluid pH levels strictly between 4 and 10.
FEATURES
- Features a heavy-duty brass cable union to strictly isolate the primary electrical feed from ambient moisture intrusion.
- Rated with an internal Class F insulation threshold to safely tolerate heavy electrical load fluctuations.
- Utilizes a Permanent Split Capacitor (PSC) motor architecture to ensure smooth rotational startup sequences.
- Equipped with internal thermal protection circuitry that acts as an immediate safety cutoff to prevent coil burnout.
- Pre-installed with a 10-metre power supply cable terminating in a standard single-phase plug for immediate deployment.
- Certified with C-Tick and CE compliance markings to guarantee strict adherence to recognized environmental standards.
- Features a 13.4 kg net weight to prevent physical shifting during automated, unattended permanent sump extraction.
