Ceramic Pump Head and Plunger Assembly for Precision Filling

Product detail

Mascera's ceramic pump head and plunger assemblies are engineered for high-precision liquid dosing applications across pharmaceutical, food, and cosmetic industries. Each set includes a ceramic plunger and matching pump barrel, housed in a 316L stainless steel shell and assembled via adhesive-free interference fit—ensuring long-term reliability under hygienic conditions.

These ceramic assemblies are ideal for OEM equipment integration, pump head replacement, or custom dosing system builds. Available in both alumina and zirconia versions, the components feature mirror-polished surfaces and ultra-tight tolerances for consistent, repeatable dosing even under continuous operation.

Mascera offers full customization based on drawings, including dimensional adjustments, fitting interfaces, and sealing surfaces to meet the demands of diverse filling systems.

Key Features

 ♦ Self-lubricating piston surface

Unique microporous structure minimizes friction and extends lifespan

 ♦ Mirror-finished internal channels

No dead corners or grooves, easy to clean and sterilize

 ♦ Anti-jamming under thermal changes

Ceramic resists sticking in alternating hot and cold conditions

 ♦ Adhesive-free structure

Ceramic and metal are joined via interference fit—no contamination risk

 ♦ High precision control

Mating tolerance < 0.02 mm; dosing repeatability within ±0.5%

 ♦ CIP/SIP compatible

Supports clean-in-place and sterilize-in-place processes

 ♦ Polished ceramic surface

Ra ≤ 0.4 µm; excellent wear and chemical resistance

Material Overview

Alumina Ceramic

• High hardness, excellent wear resistance

• Stable under high temperature and acidic/alkaline environments

• Cost-effective solution for standard precision dosing

Zirconia Ceramic

• High fracture toughness, ideal for dynamic seal designs

• Dense and smooth surface, excellent for sealing performance

• Low friction and strong chemical resistance

316L Stainless Steel

• Medical-grade, corrosion-resistant metal

• Fully compatible with CIP/SIP procedures

• Machinable for threaded/flanged/clamped structures

• Interference-fit assembly with ceramic—no glue needed

Application

 ▶ Sterile filling systems for injections, vaccines, and eye drops.

 ▶ Precision dosing of food additives, flavorings, and concentrates.

 ▶ Creams, serums, and hygienic product filling in cosmetics.

 ▶ Microfluidic delivery in laboratory or fine chemical settings.

 ▶ OEM pump replacements for ceramic plungers, barrels, and housings.
