A major change in the composition of wastewater over the years Moving to huge quantities of man-made materials as well as a dramatic increase in sand and grit content Significant increase in the number of clogging and jamming incidents Many water reducing initiatives, such as rainwater harvesting further changing the composition Expectations:
- Wastewater pumps have to be able to handle modern day wastewater
- Consume less energy and offer lower cost of ownership.

What do OFWAT think is important? PR19 commitments
Innovation must be at the core of every company to deliver long-term resilience, great customer service and affordability. We expect companies to look beyond their boundaries in addressing the challenges they face. Resilient Pump Systems Reliable Pump Stations with a reduced risk of failure. Pumps capable of managing a variable demand. Effective pump maintenance programmes.
All With Increased Cost Efficiency

Our wastewater pump stations have changed little over the past 40
- years. Many
applications have not been updated or radically changed at all in this period. Is it any wonder that we experience the same and sometimes worsening results with continual OPEX cost increases being the current solution.

The SE/SL pump design reduces electrical, mechanical and hydraulic losses without compromising reliability WIRE-TO-WATER EFFICIENCY Reduced components and reduced wear parts with flat efficiency curves ensure reduced but implementable maintenance
Reliability The unique S-tube impeller
- ffers unmatched
free spherical passage and high hydraulic efficiency LESS BLOCKING
Performance of the combined SE and SL pump program:
- Head up to 70 m
- Flow to to 270 I/s
(972 m3/h)
Performance of the S-Tube impeller:
- BEP= 83.3 %
hydraulic efficiency
- BEP = 74.5 %
- verall efficiency
- Approx. 55 % of the
curve is above 75 % hydraulic efficiency
- Free passage 110 mm
5 Years of S-Tube: Wastewater Impellers Designed for High Efficiency Without Compromising Reliability
Unfulfilled potential, why? Frameworks Culture Awareness

Closed type of impeller, with open properties. No vanes compromising free spherical passage. The bigger free spherical passage the lower risk of clogging to occur “S” derives from the extension of a natural pipe leading through the pump S-tube impellers are wet- balanced. Free Passage + Efficiency + Wear Rates = 0.5 No need to make trade offs.
5 Years of S-Tube: Wastewater Impellers Back to Basics
Grundfos have developed the first new wastewater hydraulic design the industry has seen in 20
- years. The innovative
design breaks the convention of traditional derivatives
- f open, closed or
semi open designs, by incorporating the best features of both.

5 Years of S-Tube: What Did We Say?
Free
Passage
Best Efficiency Lowest Vibration Not Advanced Add-Ons
Simple Service Solids Handling with up to 160mm Free Passage
Best in Market Efficiency up to 84% Robust as a tube or section of pipe. No expensive add-on systems or electronics. Extremely low wear rates and high reliability.
In the last 5 years, we have supplied over 5000 units to the UK market, consistently delivering radical improvements on
- perating costs, while
reducing capital
- investment. This in
turn is lowering compliance risk, and stimulating change across our client
- rganisations

Wet well Clean; Saving £6,720 a year Calls Before Per Year = 32 Man Hours Before Per Year = 256 hours Calls Now Per Year = 8 Man Hours Now Per Year = 64 hours Savings £9,600 Total Savings Per Year = £16,320
The technology is proven across hundreds of UK wastewater transfer stations, testimony’s continue to highlight the tangible benefits users are receiving.
“We quickly realised the opportunity to increase performance, reduce the chance
- f clogging, whilst considering all other cost saving implications. We estimate that
£16,000.00 in maintenance costs have been saved.“
