WEG takes part in one of the largest water infrastructure projects in Brazil
[ad_1]
Water is an indispensable resource for life and although it is a natural source, to reach people it requires efficient infrastructure and equipment. Concerned about this, Ruhrpumpen, one of the main manufacturers of pump systems in the world, chose WEG as equipment supplier to the named Ramal do Agreste project, which will take water to about 70 municipalities in the state of Pernambuco, Northeastern Brazil.
This water infrastructure is an extension of the São Francisco River Integration project with the Northeastern Hydrographic Basins. The main objective is to capture water from the Barro Branco dam, in the municipality of Sertânia and drain it into the Ipojuca reservoir, in the municipality of Arcoverde, in Brazil.
To drive the centrifugal pumps that will be installed at the pumping station, WEG is supplying three M mine slip ring motors, frame size 900, 8,000 kW, 13,800 V with special features such as the flexibility of their electrical and mechanical design. They are versatile motors that allow different configurations to suit different applications. In addition, the use of slip ring motors presents a low starting current of the motors, close to the nominal, thus minimizing the voltage drop, optimizing the substation and, consequently, reducing investments in the electrical installation.
By choosing the WEG M line motors, Ruhrpumpen invests in project reliability that will benefit around 2.2 million people, in addition to contributing to the development of the region. For WEG, being a key supplier for this project strengthens the company’s image as an important player in the Water segment and includes another supply reference in the market.

As a traditional supplier of electric motors, frequency drives, automation systems, paints and digital solutions (IOT and IA), WEG has significantly expanded its business in this sector since the company is well structured globally, in addition to participating in key wastewater and desalination projects both in Brazil and overseas.
As far as Brazil is concerned, the increase of investments in the country resulting from the new regulations for water and wastewater bring major opportunities to the supply chain of products and services.
Contributing to the country´s water, wastewater and sewage infrastructure modernization, this year WEG has supplied hundreds of W22 IR3 Premium Efficiency electric motors to public and private sanitation companies. This has happened through the “WEG Motor Bonus” program, which is an energy efficiency project conducted in partnership with electric power utilities and ANEEL that offers a bonus up to 40% to consumers who replace their old electric motors with new ones.
This initiative provides sanitation companies with technical updates, increased process reliability and reduced electricity consumption, resulting in the reduction of operating costs and, consequently, the cost of the service provided to the population.
In the overseas market, WEG is preparing to deliver the latest 7000kW electric motors for the Sorek 2 project located in Israel, one of the world´s largest desalination plants by reverse osmosis process. In addition to these motors that will be driving high pressure pumps, considered one of the plant´s most critical processes, the WEG contract includes another 42 low and medium voltage electric motors.
As stated by Elder Stringari, WEG International Director, to meet highly complex project requirements such as these, not only efficiency, but also flexibility and global structure are demanded.
“We count on a unique team dealing with major international engineering companies, who also work as constructors and operators serving this market globally. In addition, our production flexibility allows us to adapt projects to meet different applications and technical specifications, in compliance with the most demanding requirements of this market”, says Elder.
The water and wastewater market segment became one of WEG’s main business targets. The company estimates that the potential market for WEG solutions is in the range of 3% of the total CAPEX number of projects in this segment.

WEG equipment reduces water consumption at a sugar mill in Mexico
[ad_1]
The reduction in the use of natural resources in industrial processes has been increasingly necessary in the search for sustainable development. In line with this careful look, WEG has also sought to supply the market with increasingly efficient solutions that also help its customers to be increasingly sustainable.
That is why a sugar company in Mexico chose WEG to provide equipment that will save up to 95 liters of water per minute. The planetary gearbox supplied by TGM, a WEG Group company, which will activate the drying mill in one of the customer’s mills, has an air/oil cooling system, which avoids water consumption in the process since the traditional equipment in the market is the water/oil type.
The customer, who aims to reduce water consumption in all of its plants, will also achieve greater efficiency in the process, making its production chain more sustainable. It is about living today thinking about tomorrow.

WEG, new member of the Latin American Association for Desalination and Water Reuse (ALADYR)
[ad_1]
WEG, one of the largest manufacturers of electro-electronic equipment in the world, with headquarters in Brazil, has joined the Latin American Association for Desalination and Water Reuse (ALADYR) as a new member. The company’s goal is to continue growing in the water sector with partners who promote and expand desalination and reuse as real options to achieve universal access to drinking water for all
ALADYR is a non-profit trade association, the most important reference in Latin America in terms of desalination, reuse and treatment of water and effluents. Founded in November 2010, within the framework of the II International Desalination Seminar in the city of Antofagasta, Chile, the association fosters the development, promotion and gathering of timely knowledge on technologies for desalination, reuse and treatment of water and effluents, based on the provision of information exchange spaces that promote strategic alliances, projects and initiatives aimed at guaranteeing access to drinking water in Latin America under standards of sustainability, efficiency and social future.
As the main player, WEG provides the water sector with the most efficient and profitable electrical solutions, also working on the most demanding projects and works in energy efficiency around the world.

WEG contributes to increasing water supply in London
[ad_1]
The Thames Water Ring Main, is a concrete structure, with approximately 80 km of pipelines and plays a critical role in supplying drinking water in the city of London.
The main ring lies between ten and 65 meters below ground level and passes through 21 wells that serve as supply, storage and pumping stations. One of these pumping stations is Battersea Shaft, where the equipment supplied by WEG is located.
Pump infrastructure
Battersea Shaft consists of a large 30-meter-deep vertical shaft, containing six pumps that can supply multiple areas of London with drinkable water. However, increasing development in the city has made it necessary to remodel and replan the network to supply this new demand.
Due to rapidly increasing development in London, predictions suggest that there would be a significant shortage of drinking water capacity in the coming years. To accommodate a growing — and increasingly thirsty population — the station required additional pumping flow capacity. This necessitated new equipment.
With guidance from a team of experts, it was decided to replace one of the 30 mega-litre per day pumps with a new 45 mega-litre per day option.
Minimising downtime
However, the real challenge of this replacement was due to the constant demand of drinking water in the capital. To minimise disruption, the pump needed to be replaced without stopping operations.
It was decided that only the pump that needed to be replaced would be taken offline, enabling the rest of the system to continue operating as normal.
The pump supplier, Bedford Pumps, supported this entire process. Through the company’s close relationship with WEG, the team were able to replace the pump, without having to resort to cuts in the supply to the London water network.
Motor specifics
For this application, WEG engineers, along with Bedford Pumps, decided the best option was a water-cooled motor design.
The existing pump and motor had extensive fault detection instrumentation and a monitoring system. Therefore, the same range and functionality was installed in the new pump. In addition, due to the uniqueness of the location, the replacement of any wiring between the electrical equipment and the pump was invasive and required downtime, so all new instrumentation had to be selected to be compatible with the existing wiring. Further complicating the motor selection process.
WEG, expert in delivering motors for unique pumping applications, supplied for this application, a 450 kW Master Line Water Cooled induction motor. These motors stand out for the flexibility of their electrical and mechanical functionalities. What’s more, these designs are easily customised, making them interchangeable with already existing motors.
For the Battersea Shaft Pumping Station, WEG committed to achieve 96 per cent efficiency performance. Following completion of the project, during testing this figure was not only achieved but exceeded with a greater margin.
Following completion in January 2020, the pump is now fully commissioned and in full service. What’s notable, is that designing the new equipment to work with existing infrastructure, together with detailed construction planning, massively minimised the installation period for the project. And crucially, avoided pumping station outages.
The Battersea Shaft Pumping Station is another of WEG’s successful projects for the water sector. WEG motors are also fitted on the largest river water extraction pumping station in the United Kingdom, as well as the largest pumping station in Ireland.
