A piston pump is a type of positive displacement pump that uses a piston to move fluid. The piston moves back and forth within a cylinder, creating a vacuum that draws fluid in and then pushes it out. This design allows for efficient and consistent fluid transfer, making piston pumps suitable for various applications, including hydraulic systems and water supply. These pumps can handle a wide range of fluids, from water to viscous liquids, and are known for their durability and reliability. Piston pumps are commonly used in industries such as manufacturing, agriculture, and automotive for tasks that require precise fluid control.
