Grundfos opens processing plant ready to circulate water from production, bringing huge water savings and environmental benefits. Pump manufacturers who claim that their wastewater pumps are IE3 compliant are guilty of misleading consultants and end users.

The drive towards establishing a suitable standard cannot come exclusively from pump manufacturers, but sumeribles also to be driven by politicians and regulatory bodies. For example, in wet and dry installations where the same motor is used, the efficiencies will differ.

Find quick and direct information for your projects. Control pH, Recox, etc. The story behind flood control and Grundfos Jim Rise: Intelligent solutions powered by water.

Of equal importance to motor efficiency are pump hydraulics, as the possibilities for improving pump efficiency are far greater. Rotating electrical machines — Part 30 Ed. Standard methods for determining losses and grudfos from tests excluding machines for traction vehicles,which describes methods used to determine sumergkbles efficiency.

Built to handle large quantities of raw water, the pumps are ideal for a wide range of applications such as. This standard will replace the current IEC standard.


Over the past decade a substantial effort has been put into sumergihles the different test and classification standards around the globe, and the subsequent labelling schemes in use. It must be remembered that pump efficiency will decline substantially if the pump operates away from the designed BEP. This situation is starting to change and Europump is discussing proposals for an appropriate pump standard.

Grundfos believes that rather than concentrating exclusively on motor efficiency, manufacturers, consultants and end users need to address total pump efficiency defined in the ISO Get some answers from 12 thought leaders who met at a Grundfos symposium.

Features and benefits Reliability meets excellent value Quality products robust, reliable and cost-effective maximum value for money. Are you ready to connect to the future of intelligent pump systems? Providing the highest levels of total energy efficiency across all its wastewater pumps is the Grundfos objective.

Pumped by the Sun How a pump maker led the solar water systems push. However, by changing the bearings, adding a mechanical shaft seal and method of cooling, IE3 motor compliancy is negated. If this can be achieved for circulator pumps, then it follows that an internationally gombas energy standard can also be produced for wastewater pumps.

It has been automatically translated for your convenience. Safety Warnings – Update March Grundfos is issuing two safety warnings about: Nor does it tell anything about the hydraulics side, which is where the greater possibilities for efficiency gains exist.

Grundfos offers approach to missing IE3 wastewater class | Grundfos

Grundfos solution As it is impossible to claim that a wastewater pump which contains an integral motor is IE2 or IE3 compliant, Grundfos offers a solution which they consider addresses the subject of pump and motor efficiency. Wastewater pumps will typically use a double mechanical seal arrangement to prevent leakage of the pumped liquid into the motor. SE y Grundofs kW bombas de aguas residuales – alta resistencia Las bombas SE y SL son perfectas para el tratamiento de aguas residuales, aguas de proceso y aguas fecales brutas.


A technical analysis of IEC motor efficiency standards in wastewater applications. The pump industry and regulatory bodies will have to respond accordingly and invest in a testing regime suergibles gives the end users the information that they require. Each KPL grunddfos is individually engineered to suit your requirements, ensuring cost-efficient performance. Minimum, easy service Simple pump design ensures lasting, trouble-free operation All pumps are individually tested and registered; as a result, the sumergiblew spare parts can be supplied very efficiently, even after many years.

Once the pump is installed users do not want to touch it again; but equally are prepared to sacrifice some degree of energy efficiency if there are fewer breakdowns.

Grundfos offers approach to missing IE3 wastewater class

If a tender document specifies that wastewater pumps must comply with IE3, then it is impossible for any manufacturer to supply such a pump since there is no applicable standard available regarding the efficiency definitions for wastewater pumps with integrated motors. As the wastewater treatment industry is gradually moving to larger and more efficient treatment plants that require larger pumps, energy costs are going to become far more important.

The rotors and the stators from the Grundfos IE3 motor are type test certified in accordance with the TEFC motor standard and supported by measurement reports, so to all intents and purposes it is an IE3 compliant motor. It took Jason Johnson less than three minutes to connect a submersible pump, earning him top spot at the Water Pro Championship.
