Key Features & Benefits
Professional Grinder System The UNILIFT APG is equipped with a well-proven grinder system based on decades of Grundfos innovation—the same technology used in commercial SEG pump ranges. It cuts solids and particles into small pieces, allowing domestic sewage and blackwater to be pumped both vertically and horizontally over long distances to sewer mains.
Cuts Installation Time and Cost The professional grinder system reduces solids to smaller pieces, enabling domestic sewage to pass through smaller diameter outlet pipes. This allows installation of pipes as small as DN32, significantly reducing material costs and installation time compared to traditional gravity systems.
Reduces Bad Odours The UNILIFT APG can be installed in an airtight, odour-proof collecting tank with venting ports to eliminate bad smells and prevent potential leakages. Basement applications remain odour-free, allowing the space to be used for home offices or additional toilet facilities.
Flood Prevention Operating as part of a lifting station in a pressurised system, the UNILIFT APG moves wastewater above sewer level and out into the sewer system. According to EN12056-4, a lifting station is the best solution for preventing flooding caused by backflow from sewer mains.
Highly Reliable Construction The combination of cast-iron pump housing, professional grinder system, and well-proven lightweight motor concept with in-built protection and mechanical shaft seals delivers reliable, long-lasting functionality.
Easy to Maintain The lightweight 25kg design enables easy installation and handling during maintenance without requiring extra lifting devices. Compatible with multiple auto-coupling configurations including flanges (DN32/40) and pipe threads (Rp 1½”).
Applications
Lifting Station (Inside Buildings) Installed in a tank solution in basements and other building spaces below sewer level. Ideal for basement bathrooms, laundry rooms, and any below-grade sanitary fixtures.
Pumping Station (Outside Buildings) Installed outside buildings in a pumping station that leads to a public sewer or as a component in pressurised sewage systems in rural areas where gravity sewer connections are unavailable.
Stand Alone The product can be used as a standalone pump for installation in a pit solution where a complete lifting station is not required.
Installation Configurations
One Family House Single pump solution with a float switch at the pump (APG.40.10.A1 or APG.40.10.A3) or as a pump with controller for enhanced safety and additional alarm options.
Multiple Family House or Low-Rise Residential Building Two pump solution with controller provides redundancy and increased capacity for larger residential applications.
