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. Beneficios Quality products Robust, reliable and cost-effective Maximum value for money. Grundfos opens processing plant ready to circulate water from production, bringing huge water savings and environmental benefits.

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.

Grundfos Product Center Search and sizing tool to help you make the right choice. Nor does it tell anything about the hydraulics side, which is where the greater possibilities for efficiency gains exist.

The new Grundfos SBA is a complete unit and all-in-one. Grundfos SE pump mounted on auto-coupling assembly.

The range Grundfos SB and SBA are pumps sumergibles of domestic pressesure that offer a simple installation and a reliable operation in domestic applications like pozos private and tanks recolectores of water of rain. Of equal importance to motor efficiency are pump hydraulics, as the possibilities for improving pump efficiency are far greater. 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 For example, in wet and dry installations where the same motor is used, the efficiencies will differ.

This standard will replace the current IEC standard. It has been automatically translated for your convenience. 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 at a Grundfos symposium. This news article was originally written in Spanish.

If this can be achieved for circulator pumps, then it follows that an internationally recognised energy standard can also be produced for wastewater pumps. Resumen The KPL axial-flow propeller pump is designed for high flow at low head. 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.

Grundfos Facts on Pumps and Energy. The story behind flood control and Grundfos Jim Rise: The energy efficiency index EEI of the pump is calculated according to an annual load profile and the pump is labelled according to its energy efficiency. Pumped by the Sun How a pump maker led the solar water systems push.

Baseform and Grundfos collaborate to bring new, digital and smart water solutions to utility customers to optimize distribution networks, drive high energy efficiency, minimize water losses and ensure 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.

They exist models with filter of floating aspiration that extract always the just water underneath of the water of surface where is clean and without any type of solid particles.

Grundfos offers approach to missing IE3 wastewater class

Efficiency classes of single-speed, grrundfos cage-induction motors IE-codewhich defines energy classes for induction motors. Using the electrical components from an IE3 motor and installing grunffos in a wastewater pump does provide some information about the efficiency level of the entire motor unit. 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 sumeggibles 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.


This indirect test can only be used for three-phase motors. The question that has to be raised is whether a pump with an integrated motor designed for submergence in water, such as a wastewater pump, can be described as being IE2 or IE3 efficient.

Bombas In-Line Circular Grundfos

This situation is starting to change and Europump is discussing proposals for an appropriate pump standard. Built to handle large quantities of raw water, the pumps are ideal for a wide range of applications such as. The Eta 2 curve shows the hydraulic efficiency.

Story by Bryan Orchard References: Safety Warnings – Update March Grundfos is issuing two safety warnings about: Two other elements that can contribute to the motor shaft power requirement are mechanical seal friction losses and bearing friction losses, which result from the use of bomba contact bearings.

Pump manufacturers who claim that their wastewater pumps are IE3 compliant are guilty of misleading consultants and end grunddfos. Anecdotal evidence from Grundfos customers in the wastewater industry reveals that operating reliability and greater efficiency are the issues that are the most important concerns. Sumergibkes customers will test high-tech hologram glasses for the first time in the beginning of Are you a specifying engineer or facility manager?

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. Are you ready to connect to the future of intelligent pump systems?

Intelligent solutions powered by water. Providing the highest levels of total energy efficiency across grundfps its wastewater pumps is the Grundfos objective.
