Description
LEO 50SWP-QG Series Submersible Sewage Grinder Pumps (Models 50SWP12-19-2.2/QG & 50SWP12-30-4/QG)
When dealing with wastewater that contains long-fiber textiles, sanitary products, and tough agricultural solids, standard drainage pumps will inevitably jam and shut down your entire system. The LEO 50SWP-QG Series is specifically engineered to conquer these challenging environments. A heavy-duty powerhouse in the Afrogulf drainage catalog, the “QG” designation means these pumps are equipped with an aggressive, high-speed radial cutting ring at the intake. Instead of trying to pass large solids, the grinder violently shreds incoming debris into a fine slurry, ensuring smooth passage through small-diameter discharge pipes over long distances.
Because these pumps are designed for severe commercial and municipal use, they are built with an incredibly rugged cast-iron body, upper cover, and motor casing. Internally, they feature a premium stainless steel welded drive shaft and high-grade double-end mechanical seals to guarantee the 3-phase copper motor remains 100% protected during deep, continuous submersion.
What sets the 50SWP series apart is its ability to generate exceptionally high pressure. Driven by heavy-duty 3.0 HP and 5.5 HP (380V) industrial motors, the large-diameter impellers can push the shredded waste up incredibly steep vertical inclines (up to 30 meters). This makes them perfect for deep lift stations and pressure sewage networks where standard pumps cannot reach the surface.
Key Features & Specifications:
-
Reliable Grinding System: Equipped with an active radial cutting blade that shreds tough textiles, plastics, and solid fibers to completely prevent pipeline clogging.
-
High-Pressure Discharge: The specialized semi-open vortex impeller generates massive manometric head, allowing wastewater to be pushed up steep elevations and over long distances.
-
Heavy Cast-Iron Construction: The entire pump body and motor casing are forged from rigid, heavy-duty cast iron to withstand severe impacts and corrosive sewage environments.
-
Double Mechanical Seals: Features premium double-end mechanical seals (Silicon Carbide/Carbon) for absolute motor protection during continuous underwater operation.
-
Continuous 3-Phase Power: Driven by highly efficient, industrial-grade 380V motors built for heavy, round-the-clock commercial extraction.
Applications: Highly recommended for pressure sewage systems with long drainage distances and small pipe diameters. Ideal for apartment buildings, hotels, restaurants, schools, small hospitals, and agricultural stock farms where wastewater contains unpredictable solid debris.
