A reciprocating cylindrical component that creates pressure and flow in pump heads and fluid blocks by moving within a sealed chamber.
Commonly used trade names and technical identifiers for Piston / Plunger.
This component is used in the following industrial products
The core fluid-handling component of a precision metering pump that contains the pumping mechanism and fluid pathways.
The core fluid-handling component of a metering pump or valve where fluid displacement and pressure generation occur.
Control component that regulates fluid flow or actuates mechanisms in rejection gates

Pistons typically use packing rings or seals on the cylinder wall, while plungers use seals on the plunger itself. Plungers generally handle higher pressures (500+ bar) with simpler sealing arrangements.
Replacement intervals depend on operating conditions: typically 2,000-8,000 hours. Monitor for scoring, diameter wear exceeding 0.1mm, or pressure drop >15% as replacement indicators.
