This high-pressure pump ceramic piston and plunger is mainly made from zirconia ceramic, alumina ceramic or ZTA ceramic, depending on the pressure level, fluid medium and working conditions. Zirconia ceramic is often preferred for high-pressure pump applications because it offers good toughness, wear resistance and stable performance during repeated plunger movement.
This ceramic piston and plunger is commonly used in ceramic pump components, high-pressure pumps, metering pumps, chemical pumps, industrial cleaning pumps, water treatment systems, fluid control equipment and precision machinery.
Sample production usually takes 15–25 working days after drawings, material and tolerance requirements are confirmed.
Bulk order lead time is usually 25–40 working days, depending on quantity, material selection, machining difficulty and inspection requirements.
CERAMPRO custom high-pressure pump ceramic pistons and plungers are designed for pump systems where metal plungers may face wear, corrosion, surface scoring or unstable sealing during long-term operation.
These ceramic plungers can be made from zirconia ceramic, alumina ceramic or ZTA ceramic according to pressure level, fluid medium and pump structure. With precision grinding and polishing, the working surface helps reduce friction and supports smoother reciprocating movement.
This product is commonly used in ceramic pump components, high-pressure pumps, metering pumps, chemical pumps, industrial cleaning pumps, water treatment systems and precision fluid control equipment.
Different ceramic materials can be selected based on pressure, medium, wear condition and mechanical load.

High-pressure pump ceramic pistons and plungers are used in pump and fluid systems that require wear resistance, corrosion resistance and stable reciprocating movement.
Ceramic materials provide good hardness and wear resistance, helping reduce surface wear during repeated piston or plunger movement.
Zirconia and alumina ceramic can be used in many fluid and chemical environments where metal plungers may corrode or degrade.
The working surface can be precision-ground, honed or mirror-polished to support smoother movement and better sealing contact.
Ceramic plungers maintain stable dimensions under suitable working conditions, helping improve pump operation consistency.
CERAMPRO supports custom ceramic pistons and plungers based on drawings, samples or specific pump application requirements.
Specifications can be customized according to drawings, samples and pump working conditions.
