Industrial Zirconia (ZrO₂) / Alumina (Al₂O₃) Precision Ceramic Components
Description
I. Core Ceramic Components (Basic Building Blocks)
These are the “heart” materials that constitute pumps and valves, utilizing the ultra-high hardness, wear resistance, corrosion resistance, and bio-inertness of advanced ceramics (such as zirconia, alumina).
Ceramic Plunger
Description: A cylindrical ceramic moving part that performs reciprocating motion within the pump chamber to draw in and push out fluid. Its surface is extremely smooth (mirror finish), with hardness close to diamond. Paired with a ceramic cylinder, it achieves extremely low friction and nearly wear-free operation.
Typical Applications:
The core drive rod in all types of ceramic pumps.
High-precision metering equipment, fuel cell testers, laboratory pumps.
Replaces traditional metal plungers for media containing particulates, corrosive substances, or requiring high purity.
Ceramic Cylinder
Description: The cylindrical chamber that precisely mates with the ceramic plunger. The clearance between them is极小 (extremely small), forming a well-sealed working chamber. It also offers high wear and corrosion resistance, ensuring the inner diameter does not deform after long-term use, guaranteeing metering accuracy.
Typical Applications:
Paired with ceramic plungers to form the pump’s “power unit.”
Used in applications requiring zero metallic ion contamination, such as semiconductor chemical delivery and pharmaceutical synthesis.
Ceramic Valve (Valve Core, Valve Seat)
Description: The key valve components made from ceramic parts, such as the ball and seat of a ball valve, or the core of a check valve. Their “hard-on-hard” sealing method is particularly suitable for handling abrasive media and frequent on/off cycling.
Typical Applications:
The core shut-off component in groove valve metering pumps.
Chemical distribution valves in semiconductor wet processes.
Control valves for silicon texturing/etching solutions in the photovoltaic industry.
Slurry or powder slurry shut-off valves in water treatment and chemical industries.
Ceramic Parts
Description: A general term for various customized ceramic functional components, such as bearings, guides, sealing rings, nozzles, sleeves, etc. They inherit the excellent properties of ceramic materials.
Typical Applications:
Mechanical structural parts requiring wear resistance, electrical insulation, non-magnetic properties, or corrosion resistance.
Flow path components in analytical instruments, inkjet printer nozzles, fiber optic connectors.
II. Integrated Pump Systems (Functional Equipment)
These are complete devices that integrate the above ceramic components with precision machinery, motors, and control systems to perform specific functions.
Three-Piece Ceramic Pump
Description: This is the most basic and classic ceramic pump structure. As the name implies, its core consists of three main components: ceramic plunger, ceramic cylinder, and seals. A motor drives the plunger’s reciprocating motion within the cylinder. Combined with check valves (usually ball or diaphragm valves) at the inlet and outlet, it achieves fluid suction and discharge. Simple structure, easy maintenance.
Typical Applications:
Laboratory: Chemical synthesis, catalyst addition, reagent delivery.
Environmental Protection: Standard reagent addition for online water quality monitors, sampling for COD analyzers.
Food & Beverage: Quantitative addition of food additives, flavors, colorants.
Small Industrial Equipment: Serves as a universal high-precision fluid delivery unit.
Groove Valve Ceramic Metering Pump
Description: This is the benchmark product in high-precision metering. Based on the three-piece pump, it replaces traditional check valves with a unique rotating ceramic groove valve. This valve aligns with the inlet during the suction stroke and rotates to align with the outlet during the discharge stroke, achieving pulse-free, smooth, and continuous fluid delivery. It offers extremely high accuracy (repeatability up to ±0.5% or better) and performs well with viscous fluids or those containing fine particles.
Typical Applications:
Life Sciences/Pharmaceuticals: Feed addition in cell culture, precise delivery of media and buffers in vaccine production, eluent delivery in chromatography systems.
Medical Devices: Precise dispensing of samples and reagents in blood analyzers and biochemical analyzers.
High-end Chemical Industry: Precise addition of monomers in polymerization reactions, paint/coating proportioning.
New Energy: Electrolyte circulation and humidification in fuel cells.
Micro-Dispensing Pump
Description: This is a functional name for pump systems specifically designed for micro-dispensing tasks (from microliters to milliliters). It typically uses a three-piece ceramic pump or a groove valve ceramic pump as the power core, integrated with a high-precision stepper/servo motor, precision lead screw, displacement sensor, specialized dispensing heads, and a control system. It focuses on high-speed, high-precision, drip-free dispensing of tiny liquid volumes.
Typical Applications:
Pharmaceuticals/Biotech: Filling of small-dose pharmaceuticals like eye drops, insulin, vaccines.
Cosmetics: Filling of serums, perfumes, high-end skincare products.
Electronics: Precision dispensing of chip underfill, UV adhesives, conductive silver paste.
Consumer Goods: Quantitative filling of small packaged condiments, reagent kits.
