In 2021, around 11 billion tons of cargo were transported by sea worldwide. This accounts for almost 90 percent of global trade and means that the shipping industry, which has mainly been powered by heavy fuel oil until now, is responsible for around three percent of global CO2 emissions. There are other pollutants as well, like sulfur and nitrogen oxides. When it comes to clean alternative fuels, liquid ammonia (NH3) is currently coming to the fore, but it is toxic to both humans and animals and extremely harmful to the environment. This is why the pumping technology used must be compact and low-pulsation, and also hermetically tight. Moreover it must ensure maximum operational reliability. To cover these requirements in different output ranges, LEWA is presenting its triplex diaphragm pumps in a new size at this year's SMM. With an hydraulic power  of 10 kW, the LEWA triplex G3E is the smallest of its kind to date and offers a low-pulsation alternative to single-head pumps in the medium power range.
