Piston pumps are positive displacement pumps that use a reciprocating piston to move fluids through a sealed chamber. As the piston moves back and forth, it creates alternating suction and discharge cycles, enabling precise and high-pressure fluid transfer. These pumps are highly versatile and capable of handling a wide range of fluids, including those with high viscosity or containing solids. Commonly used in applications such as hydraulic systems, water jet cutting, and chemical processing, piston pumps are valued for their efficiency, durability, and ability to generate consistent flow at high pressures.
