Product Overview
Functioning as an automated heavy duty, submersible stainless steel grey water pump, the Grundfos UNILIFT AP12.50.11.A1 provides autonomous fluid management. It is structurally tailored for handling clean water, storm water, and slightly dirty wastewater across domestic and light industrial sites. The unit features an integrated float switch for hands-free operation, making it ideal for permanent sump installations or portable temporary drainage tasks.
Consistent hydraulic displacement relies on a heavily optimized 1.1 kW motor core. Running directly on a 1 x 240 V single-phase grid, the system draws a rated 8.5 Amps under full load. The internal mechanics forcefully push liquids out of a 50 mm female connection, successfully maintaining an impressive maximum flow of 500 L/Min. When pumping against vertical gradients, the unit reliably achieves a 17 metre maximum head.
Managing cloudy environmental run-off necessitates a wide internal tolerance for debris. A heavily balanced semi-open stainless steel impeller controls the main fluid vortex, allowing solid matter up to 12 mm to transit safely through the volute. This strategic clearance limits abrasive wear against the central shaft while maintaining the ability to drain standing pools down to a 100 mm minimum clearance level.
Complete environmental sealing ensures an IP68 classification, safely protecting the motor down to a 7-metre underwater depth. An intelligent cooling jacket surrounds the drive, regulating core thermals to facilitate continuous, safe pumping during partial fluid exposure. Dictated by the automatic float trigger, the pump effortlessly manages 55°C liquids and withstands ambient fluids between pH 4 and 10.
