Meet the NEW SE/SL Open S-tube® Impeller Wastewater Pumps
Dependable, energy-efficient solutions for your wastewater pumping stations and networks are essential for wastewater collection and transport.
Grundfos offers market-leading highest-efficiency sewer pumps that include innovative and patented technologies. 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.
Open S-tube® semi-open impellers provide high efficiency over a wide operating range. With the ability to be trimmed to meet a specific duty point, the SE/SL pumps fitted with Open S-tube® impellers are the ideal solution for medium to extreme contamination of wastewater.
Open S-tube® impeller eliminates clogging at wastewater station
With a bustling population of 195,000 residents, the city of Townsville in Queensland is the largest urban centre north of Australia’s Sunshine Coast. As an industrial hub in the midst of an area of rich biodiversity, framed by the Great Barrier Reef and the dry tropics region, the city’s council acknowledges the importance of reliability in the region’s wastewater systems to avoid costly and damaging breakdowns.
SE/SL pumps are designed with easy service and maintenance in mind
• The cable inlet is a plug solution that can be removed on site. The pump can easily be lifted without having to remove the cables and even without compromising the sealing when mounting the cable again.
• The shaft seal is made as a cartridge unit including both the primary and the secondary seal. This means the seal faces are protected and cannot be damaged or mounted wrongly during assembly.
• Replaceable wear rings or SmartTrim functionality to maintain high efficiency operation
• A top powder coating provides very strong corrosion protection and an easy-to-clean smooth surface. Because all surfaces are coated, repair of paint is not required following service repair.
Full range of monitoring and controls
With a Grundfos monitoring and control system, you get the information you require to maintain and optimise your wastewater system. You gain effective alarm handling, surveillance and scheduling of workflows.
LC 231 and LC 241 controller panels offer users an innovative and holistic method of controlling pump levels. While the control units house different features, they share their remotely controllable functionality via the Grundfos GO app, their intuitive and user-friendly control interface, and their simple set-up and configuration features.
