General dataMP 1, SQE-NE, SPA-NE, SP-NEEnvironmental concernConcern for the environment is growing.Waste disposal and treatment are being put into a legalframework.Investment in environmental protection is on theincrease and many sectors are taking concrete steps todevelop new solutions to environmental problems.To that end, Grundfos offers a complete product rangefor applications ranging from sampling to pumping ofpolluted drainage water.Sources of pollutionPollution of the groundwater and, thus, potentialcontamination of the drinking water resources can becaused by one or more of the following conditions:• leaking pipes, storage tanks and sewage systems• spills and leaks from tank lorries or wagons• floods, landslides, etc.In these cases, the potential damage to theenvironment can be minimised by pumping away thepollutants or the seepage water.Industrial wasteContinuous and safe production in modern industryrequires regulated disposal of waste. In the past,undesirable by products – such as residual materials orsubstances that could not be used, were often stored bycompanies on site. In the course of time, thesematerials and substances were often forgotten andsome of them seeped into the ground.Local authorities often have to deal with contaminatedsites when the companies responsible for thecontamination no longer exist or cannot afford theclean-up. Thanks to their high reliability and long life,Grundfos pumps offer a cost-effective solution.SamplingThe new Grundfos pump range featuring heads up to200 m and flow rates up to 22 m 3 /h are suitable forsampling of seepage water and groundwater. Inaddition to various geophysical methods, boreholescan be drilled to determine the chemical nature ofseepage water and groundwater in order to determinehow serious the contamination is.The Grundfos pumps are lowered into the borehole topump up water for sampling. After the sampling, thepumps are pulled up again, cleansed and lowered intothe next hole. Alternatively, the pumps are permanentlyinstalled in groundwater sampling wells for continuousduty.Industrial wastewater treatmentMany industries produce highly polluted effluent. Thelarge factories typically have their own treatmentplants, the size and capacity of which match the big cityplants.Today not only industrial process water but also coolingand surface water go through chemical and physicalpurification in separate systems before being led into awater treatment plant and then discharged or recycledinto production.Pumps are an important link between contaminatedand re-usable water. A number of environmentalprotection plants only exists thanks to the developmentof special environmental pumps, such as the costeffective,maintenance-free and highly reliableGrundfos MP 1, SQE-NE, SPA-NE and SP-NE range,based on up-to-date material combinations.TM02 0249 0405Fig. 2 MP 1, SQE-NE, SPA-NE and SP-NE pumps4
