Indar, Colorado River Basin is helping to combat drought

Published

on

Facing the worst drought on record in the Colorado River Basin, as lake levels continue to fall, the Southern Nevada Water Authority (SNWA) is building a low lake level pumping station to ensure Las Vegas and Southern Nevada maintains access to its primary water supplies in Lake Mead.

Lake Mead water levels have dropped more than 131 feet (40 meters) since the drought began in 2000. The new pumping station will allow SNWA to pump water from Lake Mead from an elevation as low as 875 feet (267 meters) above sea level into the water treatment facilities and further on to provide water to the city of Las Vegas and neighbouring communities.

Development of the pumping station consists of constructing a 315-inch diameter access shaft at more than 498 ft. depth. At the bottom of the access shaft, a 12,379 sq. ft. underground cavern is excavated. The cavern, known as a fore bay, will connect with 34 vertical shafts — each 498 feet deep and 72 inches in diameter — to accommodate the station’s 34 submersible motor pump sets. Thirty of these pump sets will be manufactured and installed by Indar.

So far, 20 low lift submersible motor pump sets (LLP) plus 10 high lift submersible motor pump sets (HLP) will be delivered by Indar.

Maria Elena Rodríguez, Water Engineering Director at Indar, explains, “The drop of Lake Mead enables wells to be drilled down in order to access those deep water reservoirs…making a traditional vertical turbine solution unfeasible to operate reliably at those depths”.

Each of those 30 Indar pumps is rated at 20,835 US gallons per minute with 433 ft. and 695 ft. of head, respectively, providing a total capacity at the pumping station of more than 900 MGD (million gallons per day). “These are more than 250 bath tubs every second” illustrates Dirk Wulf, a Project Manager at Indar.

The pumps are operated through submersible motor pump sets with 13,800-volt motors, ranging from 3,150 HP through 5,200 HP. These pump sets will obtain the required energy right from the hydro power plant at the nearby Hoover Dam. The pumps, motors, riser pipes, and well heads are made of stainless steel 316/316L in order to guarantee a long service life and to reduce the impact of the water.

In order to test the pumps and motors on full load performance, Indar has built an additional test lab 98.4 ft. deep and 158 x 197 inches wide. This $2 Million Euro investment enables Indar to guarantee the highest performance standards and a lead production schedule in order to fulfil the tight project schedule for SNWA. “Since the motor pump sets need to be ready for start-up by April 2020, we gain now the time which we had invested into the new test lab” states Jon Alberdi, General Manager of Indar Pump Division.

From the fore bay, the water will be pumped to SNWA’s water treatment facilities. The high-volume low lake level pumping station, combined with the recently completed Lake Mead Intake No. 3, will provide the community continued access to its primary water supply even as lake levels fluctuate as a result of the ongoing drought.

The design and construction cost of the Lake Mead Intake No.3 is expected to total approximately $650 million, and L3PS is on track to be operational by 2020.

“We are aware of our responsibility to enable 2 million people and an uncountable number of visitors to have their shower every morning, to have a reliable source of water and quality of life” declares Wulf. “We have considered every single detail in order to make this pumping station to be one of the most advanced and efficient pumping station in the world.” It is one of the largest already.

With this achievement, Indar reinforces its position as a leading engineered solutions provider for demanding water supply projects. Municipal water authorities, utilities, and engineering companies who have partnered with Indar have received comprehensive support from Indar’s “one-stop-shop”, gaining easily installed motor pump sets, efficient pumping, high performance, and more efficient water use.

Delicate and quiet operation with Alfa Laval’s new robust Twin Screw Pump

Published

on

Designed for handling fluids which are sensitive, abrasive, and either high or low viscosity, the Alfa Laval Twin Screw Pump is ideal for use in hygienic applications in the dairy, food and beverage, and personal care industries.

“The Twin Screw Pump is the ideal choice for both high and low viscosity liquids, all pumped perfectly with complete reliability,” says John Walker, Pump Portfolio Manager.

 Additional benefits of the Alfa Laval Twin Screw Pump are that it is quiet and virtually pulse-free, as well as being smooth and gentle during operation. These characteristics make the pump an excellent choice for handling sensitive products.

 Built on a robust, reliable platform that meets stringent hygienic standards, the pump is capable of handling both product transfer and Cleaning-in-Place (CIP). Its low pulsation characteristics and excellent solids handling capabilities reduce the risk of product damage, thereby improving product quality. Maintenance is simplified and process uptime increased.

 Process flexibility

Two-in-one operation provides easy handling of process media of varying viscosities as well as CIP fluids. This simplifies piping and pump control, cutting costs and minimizing contamination risks. Superior suction performance with excellent lift capability and low NPSHR provides installation flexibility and increases product recovery.

Service and reliability

Quick, easy seal replacement with the pump in place is made possible, thanks to a cartridge seal with a truly front-loading, self-setting design. This maximizes process uptime and minimizes maintenance costs. An optional seal service kit program adds maintenance flexibility and cuts operating costs.

Operational safety

The Alfa Laval Twin Screw Pump features a clean, external stainless steel finish with profiled elastomers and mechanical seals fully surrounded by the product. Designed for maximum cleanability using FDA-conforming materials, the pump is both EHEDG- and 3-A certified. An optional ATEX version enables use in hazardous zones.

Pumps bring comforts to travelling Pandas

Published

on

The two pandas arriving from China to Copenhagen ZOO will settle into the brand-new Panda House powered by Grundfos among others.

A technologically advanced home is waiting for the two pandas that have arrived to Copenhagen ZOO as an official gesture from China to HM Queen Margrethe of Denmark.

The 4000 square meter Panda House is designed by architect company BIG and financed by a range of Danish companies and foundations, including Grundfos.

We have supplied 15 MAGNA3 circulation pumps and one PUST pumping station to regulate heating, cooling and water, which includes a stream running through the complex.

Installation work has been carried out in cooperation with installer company C5 VVS & Ventilation A/S. For Grundfos, the project was a chance to ensure comfortable surroundings for the furry travelers in a setting, which emulates the animals’ natural surroundings.

“I am not sure we have ever delivered solutions for pandas, but together with ZOO, designers and installers, we have worked hard to ensure they will enjoy their new home. I feel privileged that we were able to back this project and contribute our knowledge and products to such a fantastic complex, designed with a great focus on animal welfare,” says Brian Sørensen, Sales Director, Grundfos.

Historic event

At Copenhagen ZOO, preparations have been underway for almost 10 years. Expectations are high ahead of the grand opening of Panda House.

“Thanks to contributions from 16 large Danish companies, we have built a facility that will raise Denmark’s profile internationally for many years to come. We have had animal caretakers, zoologists and veterinarians on education in China and been in close dialogue with Chinese professionals since 2010. And we have not least a whole plantation on South Zealand with sprawling fresh bamboo. So I dare say: we are ready to accept our newest residents, because this is, in the original sense of the word, a historic event,” says Jørgen Nielsen, CEO of Copenhagen ZOO.

Symbol of friendship

Pandas are a national treasure in China, and Denmark is only the 19th country ever to receive pandas. The gesture is a symbol of friendship and trust that rings true for overall Sino-Danish relations and the special bond between Grundfos and China.

“It is very rare that pandas are sent to other countries, so this is indeed a humbling and great honor, which illustrates the excellent friendship between Denmark and China. Our involvement in this project makes perfect sense, as we have forged strong links with China over the years,” says Brian Sørensen.

MAGNA3 gets environmental certificate

Published

on

In an industry first, our circulator pump now comes with an Environmental Product Declaration, documenting the product’s impact on the environment.

The footprints left by MAGNA3, in terms of energy consumption, chemical substances and emissions, have been detailed in an Environmental Product Declaration (EPD). It is the first time any pump manufacturer acquires an EPD in accordance with the European standard EN 15804.

“It is a very important step for Grundfos to be able to document towards our customers the environmental performance of our products in a standardised way,” says Mathias Høeg, Senior Life Cycle Assessment Specialist at Grundfos.

Widely requested

The third-party verified document, issued by independent assessors at the German Institut Bauen und Umwelt, communicates transparent, comparable information about the product’s life-cycle impact.

Having an EPD does not necessarily imply that the declared product is environmentally superior to alternatives. It simply provides facts, which are widely requested among Grundfos customers and partners.

“This area is becoming a hot topic here. As an example, with a strong focus on Nearly Zero Energy Buildings, the architect on an upcoming housing development project requires an EPD for the pumps,” says Mark O’ Sullivan, Sales Engineer at Grundfos Ireland in a sentiment echoed in various markets around the world.

 More products in sight

The next step will be to obtain the EPD for even more products, which falls in line with Grundfos’ ongoing ambitions to deliver as energy-efficient and environmentally friendly products as possible and to do so in a transparent manner.

“Working with EPDs and life cycle assessment influence the way we develop new products. Environmental performance will be considered alongside other design criteria such as price and functionality. This is possible because environment as a term can now be measured and communicated in numbers and graphs,” explains Mathias Høeg.
