Liquid temperature : 0 .. 40 °C
p max : 6 bar

Submersible Grundfos SEG sewage grinder pumps (0.9-4 kW) are designed for pumping wastewater, sludge-containing water, and sewage. Fitted with a patented grinder system designed to grind the media. SEG grinder pumps 0.9-4 kW are the perfect choice for pumping untreated wastewater and toilet waste from single houses, small communities and less populated areas as part of a pressurized pipe network where sewer systems or gravitation systems aren’t an option. SEG grinder pumps are designed for reliability and efficiency and are very cost-effective. The capability for use with smaller pressure pipes means the pumps are cheaper to install and operate, more energy-efficient and reliable for years to come
AUTOADAPT versions incorporate a controller, sensors and motor protection. Simply connect to the mains supply and the pump adapts automatically to the conditions in the pit.

SLV pumps

SLV Range
Max flow : 83 l/s
Head max : 46 m
Liquid temperature : 0 .. 40 °C

Submersible Grundfos SL sewage pumps (1.1-11 kW) are fitted with either S-tube® (SL1) or SuperVortex impeller (SLV). The free passage through the pump varies from 50-100 mm depending on size. The hydraulic design of the impeller ensures minimum clogging and maximum reliability without compromising free passage or total system efficiency. When combined with intelligent controls and high-efficiency IEC and IE3 motor components, the SL range of pumps provides an ideal solution for. Pumping wastewater is challenging. In addition to all states of water, pumps must be robust enough to ensure large solids, rags and fibres can pass freely without causing downtime and extra maintenance. The SL range of submersible wastewater pumps from Grundfos are designed to optimise your system performance with minimum servicing required.

SE pumps

SE Range
Max flow: 83 l/s
Head max: 44 m
Liquid temperature: 0… 40 °C
p max : 6 bar p max : 6 bar

Submersible Grundfos SE sewage pumps (1.1-11 kW) are fitted with either S-tube® (SE1) or Super Vortex impeller (SEV). The free passage through the pump varies from 50-100 mm depending on size. Impellers to ensure minimum clogging and maximum reliability without compromising free passage or total system efficiency. When combined with intelligent controls and high-efficiency IEC and IE3 motor components, the SE range of pumps provides an ideal solution for challenging wastewater applications. The pumps are also suitable for dry installation and do not require external motor cooling. The SE range of wastewater pumps can be permanently installed using an auto-coupling guiderail system or with a fixed pipe connection. Their internal, closed-loop cooling system means they can be used for both submerged and dry installa

SE and SL pumps

SE and SL Range
Max flow: 306 l/s
Head max: 78 m
Liquid temperature: 0… 40 °C

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 Suitable for:
1- Commercial wastewater
2- Flood control
3- Industrial wastewater treatment & reuse
4- Wastewater treatment
5- Wastewater transport
