Positive displacement pumps provide precise, consistent flow rates regardless of pressure changes, ensuring accurate fertilizer application and preventing over- or under-dosing in agricultural systems.
Stainless steel offers corrosion resistance for harsh chemicals, cast iron provides structural durability, and engineering plastics reduce weight and friction, together ensuring reliable operation with various fertilizers and extended service life.
Regular inspection and lubrication of moving parts (rotors/gears/pistons) and periodic replacement of seals/gaskets are recommended to prevent leaks and maintain precise flow control, with frequency depending on usage and fluid compatibility.
