Grundfos SEG – Grinder Pumps

Grundfos SEG — Grundfos SEG AutoAdapt

The SEG range of grinder pumps from Grundfos is specifically designed for pumping effluent and untreated sewage in small communities or sparsely populated areas with no sewer systems or where gravitation systems are unsuitable.
Pressurised systems are the perfect choice for transfer of effluent and sewage, and the SEG range combines cost-effectiveness with maximum protection for the environment by facilitating the use of smaller pressure pipes for minimal investment costs.
The SEG range is designed to reduce energy consumption and to keep downtime costs to a minimum, while maintaining peak performance throughout the system life.
The adaptive intelligence built into the AUTOADAPT versions minimises risk factors and reduces costs for installation, commissioning and maintenance.

Applications

  • Grundfos SEG pumps are specifically designed for pumping untreated sewage domestic, commercial or municipal source. High discharge pressure enables transfer of sewage over long distances.

Benefits

  • High discharge pressure enables transfer of wastewater over longer distances.
  • Plug and pump – All necessary control and protection built into the pump, eliminating complexity (AUTOADAPT version).
  • Wear resistant grinder system which grinds solids into small pieces, so they can be pumped away through discharge pipes of a small diameter.
