A reciprocating cylindrical component that creates pressure and flow in pump heads and fluid blocks by moving within a sealed chamber.
A precision-engineered cylindrical component that moves linearly within a pump head or fluid block chamber to displace fluid. It creates pressure differentials through reciprocating motion, converting mechanical energy into hydraulic energy. Critical for maintaining seal integrity and volumetric efficiency in positive displacement pumps.

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.
