Pumps maker Grundfos India has installed around 100 energy efficient pumping systems for air-conditioning and plumbing applications in 5 key metro rail projects around the country. These five projects include Chennai Metro, Mumbai Metro, Delhi Metro, Hyderabad Metro and Jaipur Metro.

The transportation sector is a major consumer of energy. Given the growing need and usage of Metros across the country, there is a huge need to provide access to mobility in cities, however ensuring low carbon emissions. The metro rail sector hence has a big opportunity to cut down the emissions by adopting a sustainable approach, one of them being the usage of advanced energy efficient products and solutions.

Given that Grundfos’ advanced energy-saving technology and high efficiency pumps can reduce the average pump’s energy consumption by up to 60 per cent, these Metro Rail projects chose to opt for Grundfos. The company offers pumps that help in reduction of life-cycle cost with high-efficiency and reliability.Grundfos made sure that every requirement for the metro rails were met especially in terms of product design, compatibility, superior technology, factory mounted tested and certified system, service support and for easy operation.

The pumps installed at these metro rail projects are:
• Hydro-pneumatic pressure boosting systems: These booster systems are made to the very highest standards and can handle even the most difficult boosting jobs with ease and accuracy. They can be used wherever additional pressure is required. Each booster model has been designed to meet specific customer demands for capacity and control.
• Grinder pumps (SEG series): Grundfos grinder pumps (SEG) are specifically designed for areas with no sewer systems or areas where gravitation systems are unsuitable. The high discharge pressure enables transfer of effluents and sewage over longer distances to the public sewer or sewage treatment plant.
• Dewatering pumps (DPK and DWK series): DWK/DPK are excellent pumps for dewatering and draining applications. The combination of compact design with high-pressure capability makes the pumps suitable for use in pits, whether for temporary or fixed installation.
• Back pull-out range of centrifugal pumps (LF Series): These pumps are used in water supply, industrial pressure boosting, industrial liquid transfer, HVAC.
• Submersible pumps (SP series): Grundfos submersible pumps are renowned for their high efficiency and reliability throughout the range. They are ideal for groundwater supply to waterworks, groundwater lowering andpressure boosting.

Commenting on the successful installation, Gangaprasad G, Vice President – Sales (Building Services), Grundfos India, said, “Metro stations are either underground or elevated ones. In an underground configuration, pumps are used for air-conditioning too apart from drainage, water supply and firefighting. Energy efficiency, reliability, low service downtime form the corner stone for any public utility service. Grundfos with its razor sharp focus on energy efficiency is a preferred brand under such considerations. With its pan-India presence, there is an assured support whenever the customer is in need of one.”
