Submersible and dry-installed Grundfos SE/SL sewage pumps (9-30 kW) are fitted with either S-tube® (SE/SE1/SE2 and SL/SL1/SL2) or SuperVortex impeller (SLV). The free passage through the pump varies from 35-125 mm depending on size and hydraulic variant.
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
