Reliable and energy-efficient wastewater pumping
Pumping wastewater is challenging. In addition to all states of water, pumps must be robust enough to ensure large solids, rags and fibers can pass freely without causing downtime and extra maintenance. The SE/SL 9-30 kW/12-42 hp ranges of wastewater pumps from Grundfos are designed to optimize your system performance.
The SE/SL 9-30 kW/12-42 hp ranges of submersible wastewater pumps from Grundfos feature the following three hydraulic concepts:
- Grundfos Open S-tube® semi-open impeller hydraulics (offered for SE/SL pumps fitted with Superhigh -or High head hydraulics. Open S-tube® semi-open impellers provide high efficiency over a wide operating range. They can be trimmed to meet a specific duty point, and SE/SL pumps fitted with Open S-tube® impellers are the ideal solution for medium to extreme contamination of wastewater.
- Grundfos closed S-tube® hydraulics (offered for SE1/SE2/SL1/SL2 pumps fitted with Superhigh -, High -, Medium -, Low and Extra low head hydraulics) or S-tube® closed impellers provide large free passage and high efficiency. SE/SL pumps fitted with the closed S-tube® impeller are ideal for low to medium contaminated wastewater.
- SuperVortex free-flow hydraulics (offered for SEV/SLV pumps). SuperVortex free-flow impellers are ideal for challenging applications with high abrasives content or long fibrous materials.
When combined with intelligent controls and high-efficiency IEC and IE3 motor components, the SE/SL 9-30 kW/12-42 hp ranges of pumps provide an ideal solution for challenging wastewater applications
SE/SL pumps: Reliable and trouble-free operation
Download the SE/SL wastewater pump brochure and find out how these pumps keep operation reliable with all wastewater flows. SE/SL pumps come with a range of hydraulic designs, for reliable and efficient operation with the highest level of performance in all wastewater applications. Available in multiple versions from 1 to 30 kW/1.5 to 42 hp, SE/SL pumps reduce your total cost of ownership with reliability proven in installations around the world.
The right choice of material increases durability
Complexities in wastewater are growing. Municipal wastewater contains elements such as organic matter, oils and greases, fibers, polymers and other substances that present us continuously with new challenges. Moreover, extreme weather conditions increase the variation of drought, rainfall and the risk of flooding, while there is a tendency to consolidate wastewater handling and centralise it in big wastewater treatment plants.
Innovative hydraulics deliver reliable operation at lower total cost, meeting the challenges of urban wastewater
To meet the increasing complexity of urban wastewater, Grundfos has developed the Open S-tube® semi-open impeller, which provides high efficiency over a wide operating range.
