Grundfos

Powerful pumps for handling unscreened raw sewage Grundfos offers a complete range of highly dependable, powerful sewage pumps, designed for handling unscreened raw sewage. With more than forty years’ experience in providing specialised pumps and pumping equipment for all kinds of wastewater and sewage, we know better than anyone what our customers demand from a wastewater pump.

> High pump efficiency over time

Advanced technology makes the Grundfos pumps extremely efficient and highly dependable. Innovative features such as SmartTrim adjustment of the impeller clearance ensure long-term high pump efficiency and low life-cycle costs.

> Less down time

The inherent non-clogging design of our SuperVortex impeller pumps and the excellent solids handling capability of our channel impeller pumps guarantee maximum up time and substantial reduction in service costs caused by pump jamming or clogging.

> Life-long reliability

The Grundfos wastewater pumps are of a wellproven design that ensures life-long reliability even under the most difficult operation conditions.

At Grundfos we strive to maintain a close dialogue with our customers in order to constantly improve our pump designs and performance. Only this way are we able to build the long-lasting relationships on which our business is founded.

Installation options

Submerged installation on auto-coupling, types S and C Submerged installation on auto-coupling system requires a base plate with a 90° bend, fixed to the bottom of the pit. When lowered into the pit along the guide rails, the pump automatically connects to the base plate. The flexible neoprene SmartSeal ensures a leak-proof connection between the pump and the auto-coupling. Type S: To prevent sedimentation of sludge at intermittent operation, we recommend a stop level corresponding to the top of the pump housing. For sufficient cooling at continuous operation, the liquid level must be kept above mid-motor level at all times. Type C: Motor cooling is independent of the pumped liquid level.

Submerged installation, portable, types S and C Certain applications, such as construction sites, require portable submersibles. Where a portable submersible is required, hoses of varying lengths and materials can be supplied. Type S: To prevent sedimentation of sludge at intermittent operation, we recommend a stop level corresponding to the top of the pump housing. For sufficient cooling at continuous operation, the liquid level must be kept above mid-motor level at all times. Type C: Motor cooling is independent of the pumped liquid level.

Vertical dry installation, type D The Grundfos sewage pumps can be installed vertically or horizontally to suit specific application arrangements. The pumps are 100% watertight, allowing for dry installation with the workspace around the pump remaining clean and dry. If an unexpected flooding should occur, the Grundfos pumps are fully flood-proof. Motor cooling is effected by internal cooling of the pump.

Horizontal dry installation, type D Horizontal dry installation improves the overall efficiency of the pumping system as unnecessary components and bends are avoided. As the system takes up slightly more space than a vertically installed pump, the feasibility of horizontal dry installation depends on the floor space available. Motor cooling is effected by internal cooling of the pump.

Grundfos SuperVortex impellers

A unique impeller design The unique design of the Grundfos SuperVortex impellers provides high pumping efficiency and less downtime. With a flow range from 4 l/s, the Grundfos SuperVortex-impeller pumps are the optimum solution for all small pumping stations.

No clogging or jamming In a SuperVortex-impeller pump, the flow is entirely outside the impeller. The design of the impeller ensures that long fibres, rags, etc. pass freely through the pumps without getting caught and without causing clogging or jamming. This means less downtime and, consequently, reduced service costs and
