Medical pump pistons and valves
Pistons, cylinders, and valve parts for dialysis, infusion, and laboratory pumps.
Product family
Ceramic pistons, valves, filling parts, blades, and wear parts for medical devices, laboratory instruments, and food processing equipment where corrosion, hygiene, and wear matter.

Product overview
Medical and food equipment uses ceramic parts because they resist corrosion from cleaning agents, do not rust, and wear slowly against fluids and food. Zirconia and high-purity alumina are the usual choices.
Typical requests include dialysis and laboratory pump pistons and valves, food filling pump and valve parts, beverage dispensing valves, ceramic parts for meat grinders and food cutting, and wear parts in packaging and processing machines.
Material declarations, cleaning, and packaging are part of the requirement. The finished part does not certify the device or machine; state the documents you need so they can be confirmed in the quotation.
Product types
These are made to customer drawings or samples, not sold from stock. Final material, route, and acceptance are confirmed for each drawing.
Pistons, cylinders, and valve parts for dialysis, infusion, and laboratory pumps.
Filling pistons, valves, and nozzles for food and beverage machines.
Ceramic cutting plates and grinder parts for food processing.
Guides, sleeves, and pins in packaging and processing machines.
Decision map
Use the final column as a drawing and RFQ check. A requirement is easier to review when its function and acceptance evidence are stated together.
| Requirement | Why it changes the route | What to define in the RFQ |
|---|---|---|
| Material declarations | Food-contact and medical uses often need composition or compliance documents. | List the declarations or test reports needed and the applicable regulation. |
| Cleaning and packaging | Residues and particles must be controlled before parts enter the device. | Specify cleaning standard, packaging, and labelling. |
| Running fits and finish | Pump and valve performance depends on clearance and surface finish. | Define fits, Ra, and how parts are matched or tested. |
Material paths
Tough, polishable, and common for pistons, blades, and valve parts.
Hard and chemically stable for valve plates, cylinders, and seats.

Engineering guides
Each guide below narrows one part family or manufacturing constraint and leads back to the drawing information needed for review.
Design and RFQ guide for ceramic pump and valve components used in corrosive, abrasive, high-purity, and vacuum fluid systems, including SiC seal faces, zirconia balls, alumina seats, plungers, sleeves, lapping, and inspection.
RFQ guide for ceramic needles, plungers, valve parts, flow cells, and micro-nozzles where carryover, dead volume, media, sealing, cleaning, and inspection must be defined.
Engineering RFQ guide for precision ceramic components used in cleanroom and high-purity manufacturing systems, covering alumina, zirconia, SiC, AlN, nozzles, sleeves, spacers, rings, plates, cleaning, packaging, inspection evidence, and qualification boundaries.
Questions before quotation
Certification is not implied. State the documents you need, such as composition declarations or migration tests, so availability can be confirmed before order.
Engineering RFQ
Start with the part function, material or grade if known, quantity, and the critical requirements; an early-stage brief is enough to begin. If online submission is interrupted, the form prepares the same RFQ as an email instead.
