Description
The waterjet intensifier ceramic plunger for the water jet is used on 60k ultra high-pressure intensifier waterjet pumps 50HP, 60HP,100HP, 40KPSI, and 60KPSI. The max pressure it undertakes can be 60 kpsi , voltage of 220v/380v.
The ceramic connects with the metal cap by heat shrinkage, it is the strongest assembling ceramic to metal, not easy to fall apart. The surface of the zirconia rod is mirror polished, with fine surface roughness, so it is wear-resistant and can work a long time . And zirconia ceramic material with good toughness and fracture strength. Below is the waterjet cutter machine intensifier pump structure with a zirconia ceramic plunger for reference:
