Grundfos Unilift APG.40.10.A1 Submersible Drainage Wastewater Macerator Pump 240v

The Grundfos Unilift APG.40.10.A1 is a compact, high-performance submersible grinder pump engineered to handle domestic wastewater and blackwater in pressure sewer systems. Designed for residential sewage applications, it features a powerful integrated grinder system that shreds solids into fine particles, allowing wastewater to be pumped through narrow-diameter discharge pipes — ideal for properties without access to traditional gravity sewer systems.

Built for reliability, the APG is constructed from robust cast iron and corrosion-resistant stainless steel, with a smooth exterior that prevents buildup of fats and solids. The wear-resistant grinder impeller is housed within a cast iron volute and powered by a high-speed 1.3 kW motor with thermal protection and IP68 submersible rating for long-term performance in challenging pit conditions.

The APG.40.10.A1 is supplied with a 10 m power cable, Schuko plug, and a DN32/DN40 threaded outlet for easy connection. It’s compatible with auto-coupling guide rail systems for hassle-free installation and removal — especially suited for retrofits and new builds in difficult terrain.
