Grundfos SE1.80.100.55.A.Ex.4.50B.B.R (92871049)
Non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water and unscreened raw sewage. The pump is designed for intermittent and continous operation. The liquidless and maintenance free cooling system ensures that the pump can be used for submerged or dry installation. The revolutionary S-tube® impeller provides free spherical passage of solids up to 80 mm and is suitable for wastewater with a dry matter content of up to 3 %. A unique stainless-steel clamp assembling system enables quick and easy disassembly of the pump from the motor unit for service and inspection. No special tools are required.

Applications
- Commercial wastewater — Commercial buildings have vastly different requirements for wastewater transfer. Grundfos supplies wastewater pumps and lift station pumps ensure superior reliability and safety, as well as high efficiency.
- Flood control — Grundfos supplies complete flood control systems to protect urban and rural areas, infrastructure and large cities from flooding. Our innovative solutions meet the high-flow and low-head requirements at the flood pumping station or pump gate.
- Industrial wastewater treatment & reuse — Grundfos offers solutions that add value to every step of wastewater treatment required for safe and compliant discharge or for water reuse in your facility. You get the most efficient treatment combined with intelligent measurement and control for maximum safety and minimum downtime.
- Wastewater transport — When continuously transporting wastewater, you need reliable and optimised solutions for wastewater pumping stations and networks. Better system design, for example by using CFD simulations, tackles hydraulic issues in advance, reduces downtime and minimises risk.
- Wastewater treatment — Treating wastewater is about maintaining optimal and effective processes at mechanical, biological and chemical treatment stages. A full-line supplier, Grundfos ensures that hydraulic stability is maintained and capacity not exceeded for all processes.
