- How fragile are your ceramic materials?

Ceramic materials are, in general, sensitive to mechanical shocks.
To deal with this issue, Neoceram has developed Pharmazirc®, an exceptionally robust material for applications where fragility can be a problem.
In addition, the Neoceram engineering department possesses all the necessary knowledge of the process and understanding of the materials to minimize the fragility of the finished product through the choice of the best design and protections.

- What is the process?

Our raw materials are very fine grain powders selected from the most stringent specifications available on the market. The powders are blended with proprietary additives and formed into billets, using extreme pressures from an isostatic press. The billets are then fired, over a carefully controlled time/temperature cycle, to reach the desired mechanical properties. The shaped items are then fine ground, assembled with the stainless steel components and mated. Our product quality control includes functional and leak tests.

- What are the advantages of ceramic pumps?
  • Pharmalox® and Pharmazirc® show superior hardness and no porosity, a combination of characteristics which lead to a final product with an extremely high resistance to wear and corrosion.
  • Our pumps release much less particles than other materials normally used for filling applications, whatever the filled product.
  • Pharmalox® and Pharmazirc® can be machined to very fine precision which, in conjunction with their stability, results in much improved filling accuracy over time.
  • Their low expansion coefficient makes them ideal for use in CIP/SIP conditions.

- Can ceramic pumps run dry?

Yes, because of their low friction coefficient, ceramic pumps can run dry without seizing up.

- Can ceramic pumps run at high temperature?

Yes. Nevertheless, the T° of use should be communicated to our sales representative prior to ordering the pumps, to allow the definition of the best option for material selection and clearance.

- Can ceramic pumps be autoclaved?

Yes, ceramic pumps can be autoclaved. We recommend that they be disassembled prior to autoclaving.

- What about product compatibility and product contact?

Pharmalox® and Pharmazirc® are chemically inert, their fine grain allows for a much smoother surface finish than standard GMPs. Ceramic samples are available upon request.

- What about crystallizing products and suspensions?

Our pumps can run with most suspensions and crystallizing products. Nevertheless, we advise the customer to send us a sample of their product, with the specification of the filling parameters, so that we can perform in-house tests and custom design the best possible solution.

- Can ceramic pumps be repaired?

Yes, a male or female part can be repaired/replaced, but will have to be mated again to the piston or to the housing of the original pump.

- How do you clean ceramic pumps?

Ceramic pumps can be cleaned as any other pump with WFI and any other detergent (basic or acid) that is available on the market. Ceramic pumps can also be cleaned in an ultrasonic bath.
Usually they do not require any change or amendment of existing cleaning procedures.

- Do ceramic pumps need special care during handling?

As with any other high precision product, ceramic pumps should be handled with care. Light shocks during cleaning and/or autoclaving will not damage them nor cause seizure during production. Heavy duty trays that hold the pumps, minimizing handling during cleaning and autoclaving, can be purchased. A user manual detailing pump assembly, handling instructions, cleaning procedures, conditions of use and trouble shooting is provided.
