Grundfos offers approach to missing IE3 wastewater class
For example, in wet and dry installations where the same motor is used, the efficiencies will differ. Wide choice All models available in cast iron or stainless steel 50 or 60 Hz special materials such as propeller in aluminium bronze as standard and stainless steel available on request high-voltage models available, up to 10 kV on special request pump and motor size up to 1 MW on special request.
By introducing energy labelling, the end user can compare products and specify the most appropriate pump, or pumps, for the installation. Safety Warnings – Update March Grundfos is issuing two safety warnings about: How can India solve its urban water issue? Once the pump is installed users do not want to touch it again; but equally are prepared to sacrifice grundfoa degree of energy efficiency if there are fewer breakdowns.
Providing the highest levels of total energy efficiency across all its wastewater pumps is the Grundfos objective. Minimum, easy service Simple pump design ensures lasting, trouble-free operation All pumps are individually tested and registered; as a result, the right spare parts can be supplied very efficiently, even after many years.
To sum up, it is all the losses in the system that requires a clearly defined method of testing, but to do so would involve establishing a facility which replicates the installation. The main reason why an efficiency standard has not been introduced to date for wastewater pumps could be due to the fact that manufacturers, legislation and standard makers see wastewater pump motors as a separate unit and not as a unit integrated in the pump, and therefore they are having difficulties in defining the motor friction losses and efficiency.
The values and basic ideals of the company, property of the Foundation Poul Due Jensen with headquarters in Bjerringbro Denmarkreflect so much in his products as in the relations with his employees, customers, the society and the environingingment.
Rotating electrical machines — Part 30 Ed. It has been automatically translated for your convenience. Efficiency is an issue that affects all pump users in the wastewater industry and it becomes even more important when the pump motor increases in size. Reasonable efforts have been made to provide an accurate translation, however, no automated translation is perfect nor is it intended to replace a human translator.

The new Grundfos SBA is a complete unit and all-in-one. This news article was originally written in Spanish. A technical analysis of IEC motor efficiency standards in wastewater applications. Nor does it tell anything about the hydraulics side, which is where the greater possibilities for efficiency gains exist.
Are you ready to connect to the future of intelligent pump systems? It has designed on the bases of the contrasted range SB but includes a unit of control integrated — that deletes the need of a controller of external pumping.
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.
For optimum results, contact Grundfos during your planning stages; that allows us to consider aspects such as pumping station design, pump selection, future requirements, and the total life cycle costs. Get the job done faster and better with quick and direct guidance and support for all phases of your project. The bomb in himself same is very silent and, if it installs under earth, in a tank recolector of pluvial waters or in a pozo, the noise never will be a problem.
New inverter expands solar pump range Make your pump solar-ready.
Designing pumping stations the right way. Two other elements that can contribute to the motor shaft power requirement are mechanical seal blmbas losses and bearing friction losses, which result from the use of angular contact bearings. The range SBA includes protection against course in dry integrated since they are available with switch of level for small cuttings of water. Anecdotal evidence from Grundfos customers in the wastewater industry usmergibles that operating reliability and greater efficiency are the issues that are the most important concerns.
Over the past decade a substantial effort has been put into harmonising the different test and classification standards around the globe, and the subsequent labelling schemes in use. 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.
Get some answers from 12 thought leaders who met aumergibles a Grundfos symposium. The sumergkbles towards establishing a suitable standard cannot come exclusively from pump manufacturers, but has also to be driven by politicians and regulatory bodies. Flotadores por aire disuelto Toro Equipment, S. This indirect test can only be used for three-phase motors.
Of equal importance to motor efficiency are pump hydraulics, as the possibilities for improving pump efficiency are far greater. Story by Bryan Orchard References: For an automatic operation, the range SB requires of the installation of an external controller, like the system Pressesure Manager of Grundfos.

Built to handle large quantities of raw water, the pumps are ideal for a wide range of applications such as. Besides all the range is manufactured in composite and materials of stainless steel what does him resistant to the corrosion.
In the absence of an appropriate energy efficiency standard for the pump, it is inevitable the manufacturers and vendors are going to highlight grujdfos IE3 connection.
What it does not provide is any specific value because the friction losses in a wastewater pump are different from those present in a standard pump and these losses are not taken into account. The other indirect method involves measuring the input power and calculating the total losses by measuring and adding individual loss components.
Las bombas SE y SL son perfectas para el tratamiento de aguas residuales, summergibles de proceso y aguas fecales brutas.
