Energy efficient pumps for the shipbuilding industry
The Chinese maritime sector is starting to take notice of Grundfos, a global pump manufacturer. The company is pioneering solutions to cut energy on marine vessels.
“Grundfos is strong in providing energy efficient on-shore products and these applications can be transferred to the shipping industry. We see huge opportunities as the environmental agenda continues to play an important role within the marine sector. We have developed innovative seawater resistant pumps and we are continuing to build up a strong portfolio through further research and development,” explains Morten Gylling, Segment Director, General Industry.
The cutting-edge technology used in Grundfos pumps allows the energy consumption related to engine cooling to be reduced by as much as 75% by automatically adjusting the pump speed to the temperature of the seawater and/or to the engine load. As approximately 90% of a pump’s total cost stems from the energy consumption, this makes for significantly reduced life cycle costs. Grundfos’ product range is suitable for a variety of marine applications such as seawater and freshwater cooling pumps, boiler feed and utilities.

Gylling: “We have been very active within the Chinese market and are dedicated to continue working alongside our partners in China, particularly Chinese shipyards. As energy reduction and environmental awareness debates continue within the Chinese marine industry, we understand that we must be dedicated to the Chinese market and ensure our products are available to our customers and partners throughout China.”
With more than 18,000 employees – 1,500 of them in China at two factories and several sales offices – Grundfos produces more than 16 million pump units a year. The production of these circulator pumps, submersible pumps and centrifugal pumps covers some 50% of the world market for these pumps and pump systems. Grundfos also produces electric motors and electronics for controls for pumps and other systems.
