The main accessories of the Firsle FN series plastic circulating water pump are made of special plastic that is resistant to high and low temperatures, durable, easy to operate, and easy to maintain. Plastic circulating water pumps are particularly suitable for transporting highly corrosive liquids, such as acidic and alkaline solutions, seawater, chlorinated water, purified water, etc., because plastic materials such as polypropylene (PP) and polyvinylidene fluoride (PVDF) have excellent chemical corrosion resistance. Plastic circulating water pumps often adopt optimized designs to improve efficiency, and due to the insulation properties of the material, they can effectively prevent electrochemical corrosion, thereby improving the overall efficiency of the equipment and reducing energy consumption. The friction coefficient between plastic parts is small, resulting in low noise during operation, which is beneficial for improving the working environment. Compared to traditional cast iron or metal circulating water pumps, plastic circulating water pumps are lighter in weight, reducing the difficulty of installation and handling. At the same time, some plastic materials have a longer service life under normal usage conditions.
