Submersible Grinder Pump SEG.40.15.2.50B

The Grundfos SEG.40.15.2.50B submersible grinder pump is specifically designed for pumping wastewater, sludge water, and sewage in areas lacking gravity drainage systems. This model is ideal for applications in commercial buildings, domestic wastewater systems, and general sewage transport. Thanks to its advanced grinding system, the pump can shred solids present in the wastewater, allowing them to be propelled through small-diameter pipes, which is especially useful in rural areas, villages, and terrains with significant gradients.

The patented Grundfos grinding system, integrated into the SEG.40.15.2.50B, breaks down solids into smaller fragments, enabling continuous and efficient flow in pressurised pipe systems. This single-stage centrifugal pump, with a horizontal discharge port, is an effective and reliable option for managing pumping needs in areas where conventional drainage systems are not feasible.

Additionally, the SEG.40.15.2.50B is manufactured with highly wear-resistant materials, such as cast iron for the casing and impeller, ensuring a long service life and increased durability even in challenging conditions. The pump's smooth surfaces prevent the accumulation of dirt and debris, facilitating maintenance and ensuring consistent performance.

The Grundfos SmartTrim system is an important feature in this model, allowing users to easily adjust the impeller clearance to maintain the pump's optimal efficiency throughout its lifespan. This translates to lower operating and maintenance costs, making the SEG pump a cost-effective long-term solution.
