GRUNDFOS submersible sewage pumps, types SL1 and SLV, are designed for pumping sewage and wastewater in various applications, including municipal, private, and industrial settings. The pumps are made of resistant materials, such as cast iron and stainless steel, and are fitted with motors from 1.5 hp to 15 hp. They have a free passage of 2 to 4 inches and are available for submerged installation on auto-coupling systems or free-standing. The pumps are ideal for transferring liquids, including municipal wastewater, wastewater with high fiber content, drainage and groundwater, domestic wastewater, industrial wastewater, and process and cooling water. They feature corrosion-resistant cable entries, power cables with thermal sensors, and moisture detectors for continuous monitoring. The pumps also have heavy-duty bearings, smooth surfaces to prevent dirt and impurities from sticking, and self-cleaning channel impellers or SuperVortex impellers to reduce jamming or clogging. Explosion-proof motors are available for potentially explosive environments. The pumps have a service-friendly design with clamp connections, cartridge shaft seals, and cable connections via plugs. They are built with highly efficient EFF1 components, offering lower motor temperatures and longer life.
