Biological Treatment

SE/SL come in three hydraulic concepts for different wastewater contamination levels (semi-open, closed and free flow impellers). The product range is designed for its environments, with extreme durability that covers aggressive environments. Grundfos mixers and flowmakers keep particles evenly distributed in the wastewater and sludge and can be controlled with Grundfos variable speed drive for optimised energy efficiency.

The Aerojet can help to avoid odour problems during wastewater storage and keep the treatment process running. Since it is submersed, no harmful aerosols are dispersed into the surroundings.

1. Endsuction close coupled single-stage pumps - NB/NBE
End-suction close-coupled pumps according to EN 733. The pump has an axial suction port, radial discharge port, horizontal shaft and a back pull-out design enabling removal of the motor, motor stool, cover and impeller without disturbing the pump housing or pipework.

2. Submersible wastewater pumps - S
The S pumps are a range of free-flow channel impeller pumps specifically designed for pumping sewage and wastewater in a wide range of municipal and industrial applications.

3. Submersible wastewater pumps - SE, SE1, SEV
Submersible Grundfos SE sewage pumps are fitted with either S-tube (SE1) or SuperVortex impeller (SEV). The free passage through the pump varies from 50-100 mm depending on size.

4. Submersible wastewater pumps - SEG
Submersible Grundfos SEG sewage grinder pumps are designed for pumping wastewater, sludge-containing water, and sewage. Fitted with a patented grinder system designed to grind the media.

5. Submersible wastewater pumps - SL
Submersible Grundfos SL sewage pumps are fitted with an S-tube® impeller. The free passage through the pump varies from 50-100 mm depending on size.

6. Submersible wastewater pumps - AP/APG
AP pumps are designed for pumping wastewater, sludge-containing water, groundwater and sewage. APG are equipped with cutter system for grinding solids into small pieces.

7. Submersible wastewater pumps - EF
Grundfos EF pumps have a single-vane, semi-open impeller for 30 mm free passage, designed for pumping effluent and other liquids such as drainage and surface water with fibres and small impurities.

8. Digital Dosing Pumps - SMART Digital S/XL
SMART Digital diaphragm dosing pump with powerful variable-speed stepper motor (S) or powerful PMS (Permanent Magnet Synchronous) motor (XL) and FlowControl system to automatically detect malfunctions. High-end solution for complex and demanding applications with turn-down ratio up to 1:3000.

9. Mechanical Dosing Pumps - DMH
The DMH range is a series of extremely strong, robust hydraulically actuated piston diaphragm dosing pumps for applications requiring reliable dosing and high-pressure capability, such as process engineering. The range is highly versatile: it covers a wide flow range and offers a variety of dosing head sizes, materials and accessories.
