The Grundfos UNILIFT AP series is built for installers who need dependable wastewater pumping without the guesswork. This lineup includes the UNILIFT AP12.40.06.A1 1x230V and the UNILIFT AP12.40.06.3 3x400V, both designed for use in separators and pumping stations. Whether you are working on a residential basement, a commercial facility, or an industrial site, these submersible pumps handle dirty water, sludge, and light solids with ease. You get a straightforward, reliable solution that stands up to daily use.

Rugged Construction for Long Service Life

These pumps are made from chromium-nickel stainless steel, which resists corrosion and handles harsh wastewater environments. The robust impeller and wear-resistant components mean fewer breakdowns and less downtime on your job site. You can count on the UNILIFT AP to run continuously in demanding conditions while keeping maintenance simple and cost-effective. The durable build protects the motor from abrasion and chemical exposure, giving you a pump that lasts.

Flexible Power and Cable Options

Installers appreciate the clear wiring choices. The 1x230V model comes with a 5-meter cable and a SCHUCO plug for quick, tool-free connection to standard power sources. The 3x400V version features a 10-meter cable without a plug, making it ready for direct connection to three-phase distribution boards. Both options are designed to fit standard electrical setups, saving you time and reducing on-site wiring complications.

Optimized for Pumping Stations and Separators

The UNILIFT AP series is engineered to work seamlessly in wastewater pumping stations and separator systems. It delivers steady flow rates, handles variable water levels, and includes built-in thermal protection to prevent motor damage during dry running or overload. The compact design fits easily into tight sump pits, while the integrated float switch ensures automatic start and stop cycles without extra wiring.
