Quick Summary
A piston pump is a device that uses a reciprocating piston within a cylinder to move and pressurize fluids. This mechanism converts rotary motion into straight-line motion, or vice versa, essential for pumping.12
How it Works
- Suction Stroke: As the piston moves outward, it creates a partial vacuum. Atmospheric pressure then forces fluid into the cylinder through an inlet valve.3
- Discharge Stroke: When the piston moves inward, it increases the pressure within the cylinder, forcing the fluid out through an outlet valve.3
Piston pumps are known for their reliability and durability, with some operating for over a century without repair. They are a type of positive displacement pump, meaning they move a specific volume of fluid with each cycle.3
