Grundfos Seg Grinding Pump Is a Non Self-Priming Single-Stage Centrifugal Pump for Sewage Treatment

SEG.50.40.EX.2.50B
The Grundfos SEG grinding pump is a non-self-priming single-stage centrifugal pump with a horizontal discharge port, specifically designed for pumping wastewater containing toilet discharges. The pump is equipped with a grinding system that can grind destructible solids into small pieces, allowing them to flow away through relatively small-diameter pipes.

The SEG grinding pump is highly suitable for use in densely populated areas where a gravity sewage system is not feasible. For example, in villages, farmlands, and regions with significant topographical height differences, the pressurized system can offer advantages. There are two types of installations for the pump:

Submersible installation within the automatic coupling system
Submersible installation, independent type.

The pump is made of wear-resistant materials such as cast iron and stainless steel. These materials ensure reliable operation. The surface of the pump is smooth to prevent dirt and impurities from adhering. Corrosion-resistant stainless steel clamps fix the motor to the pump casing, facilitating the maintenance of the pump. The SmartTrim system enables easy adjustment of the impeller clearance, ensuring the highest efficiency throughout the service life of the pump.

This series is designed to reduce energy consumption, minimize the cost of downtime, and maintain optimal performance throughout the entire life cycle of the system. The pump is an explosion-proof pump.
