Seawater pumps are widely used in marine engineering, mariculture, marine disaster prevention, coastal landscape water conservancy, shipbuilding, brine-cooled air conditioning, and road washing. For example, in marine aquaculture, seawater pumps can disperse seawater onto farmed organisms, promoting their growth and development; in marine disaster prevention, seawater pumps can quickly remove seawater from disasters such as tsunamis, reducing damage.
The key features are high resource utilization efficiency. It uses seawater as the "source" but does not consume or pollute it; its thermal efficiency is high, consuming 1 kilowatt of electricity to obtain 3 to 4 kilowatts of heat or cooling, unlike traditional energy utilization methods. Furthermore, its energy cost per unit of heat output is lower than that of traditional electric and gas boilers, resulting in lower operating costs.
