Fluid End Plunger

The Fluid End Plunger is a core moving component used in the hydraulic end of high-pressure reciprocating pumps, suitable for high-pressure, high-frequency, and highly abrasive operating conditions.

Long wear-resistant life: Utilizing an alloy steel substrate with surface hardening treatment (chrome plating/ceramic coating), the surface hardness can reach HRC 60–65.

Stable high-pressure seal: The outer diameter is precision ground and polished, resulting in low surface roughness (Ra ≤0.2 μm), ensuring stable adhesion with the filler and reducing leakage and scoring.

Corrosion resistant: Made of stainless steel or corrosion-resistant alloy materials, it can withstand the erosion of acids, alkalis, and sand-containing media.
