Submersible wastewater pumps – SEG.40.40.2.50B

SEG.40.40.2.50B

Grundfos SEG grinder pumps are non-self-priming, single-stage, centrifugal pumps with horizontal discharge port, specifically designed for pumping wastewater containing discharge from toilets. The pump is equipped with a grinder system that grinds destructible solids into small pieces to lead them through pipes with a relatively small diameter. SEG grinder pumps are ideal for use in sparsely populated areas, where gravity sewage systems are not available. Examples include villages, farm areas and areas with large terrain-level differences, where a pressurised system has advantages. The pump is available for two types of installation:
submerged installation on auto-coupling systems
submerged installation, free-standing.
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 sticking. The corrosion-resistant stainless-steel clamp is securing the motor to the pump housing and allow the easy service of the pump. Smart Trim system allows easy adjustment of the impeller clearance to ensure maximum efficiency during the pump lifespan. The range is designed to reduce energy consumption and keep downtime costs to a minimum, while maintaining peak performance throughout the lifespan of the system.
