The Grundfos SE series sewage pumps are known for their fault free and high reliability. It can be installed either underwater immersion or dry installation without the need for motor cooling, making it durable and easy to maintain. This product can be permanently installed through a self coupling guide rail system or fixed pipeline connection, or it can be freely installed vertically. At present, the S-shaped tube impeller is in a dominant position in the market and can cope with various types of sewage with dry particulate matter content. The special flow channel design further enhances the hydraulic efficiency of the pump while ensuring that the maximum particle diameter remains unchanged.
