Waterjet Zirconia Ceramic Plunger

Innovacera develops many kinds of Zirconia ceramic parts for all kinds of pumps & valves. Such as waterjet zirconia ceramic plunger for severe service and high-pressure systems.

Ceramic pumps and plungers are the ideal replacements for the metal in high pressure, high wear, high temperature, saltwater, chemical, and metering applications.

The waterjet intensifier ceramic plunger for the water jet is used on 60k ultra high-pressure intensifier waterjet pump 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, and 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 for 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:

What Is The Outstanding Characteristics for ZTA?

ZTA (Zirconia Toughened Alumina) is a composite material made from alumina and zirconia. It combines the outstanding characteristics of both materials.

Compared to conventional alumina, ZTA possesses superior hardness, higher flexural strength, and similar density. Compared to conventional zirconia, it possesses a lower coefficient of linear thermal expansion and higher thermal conductivity.

By leveraging these features, ZTA has been widely adopted in milling parts and wear-resistant parts that require cooling.

ZTA (Zirconia Toughened Alumina)

Features:

• High Stiffness and Outstanding Wear Resistance
• Stiffer than alumina with outstanding wear resistance equivalent to zirconia.
• High Thermal Conductivity and Low Thermal Expansion
• Suppresses thermal deformation through thermal conductivity and low thermal expansion equivalent to alumina. Suitable for components requiring a cooling Mechanism.
• High Strength and Specific Rigidity
• Approximately twice as strong as alumina and contributes to low-weight design through high specific rigidity.
