Product Overview
Operating explicitly as a heavy duty, submersible stainless steel grey water pump, the Grundfos UNILIFT AP12.50.11.1 is engineered for reliable fluid transfer. It is structurally designed to handle clean water, storm water, and slightly dirty wastewater across both domestic and light industrial applications. The unit offers flexible deployment capabilities, functioning efficiently within permanent plumbing installations or acting as a portable drainage asset for temporary fluid relocation.
Hydraulic performance is driven by a highly efficient 1.1 kW motor mechanism. Powered via a 1 x 240 V single-phase electrical supply, the robust core operates with a rated draw of 8.5 Amps. Fluid is discharged through a 50 mm female threaded connection, allowing the internal volute to securely output a maximum flow of 500 L/Min. During vertical extraction cycles, the unit effectively scales the fluid column to establish a 17 metre maximum head.
Continuous operation in dirty environments requires a fortified internal circulation pathway. The pump incorporates a precision semi-open stainless steel impeller that allows the safe transit of solid environmental particles up to 12 mm in diameter. This specific geometric clearance prevents suspended matter from causing rotational jams while permitting the system to safely draw standing water down to a 100 mm minimum pumping level.
Built entirely from premium 304 stainless steel, the IP68-rated motor permits submerged underwater installations down to a 7-metre maximum depth. An integrated motor cooling jacket consistently dissipates internal heat, allowing for extended continuous operation even when only partially submerged. The pump safely processes fluids with a pH between 4 and 10 and handles liquid temperatures up to 55°C, with a brief tolerance of 70°C for two-minute intervals.
