Plastics

CP offers a choice of solid plastic and plastic lined pumps. When in contact with many acids, plastics are generally more corrosion-resistant than most grades of steel. What is more, they are less expensive than metal alloys for constructing equivalent pumps.

PFA lining

PFA (perfluoroalkoxy) has similar properties to PTFE (polytetrafluoroethylene). The difference from PTFE is that PFA is more easily formable by melt-processing and extrusion techniques. In comparison with similar materials, PFA offers the highest continuous service temperature (up to +260°C) while remaining creep-resistant and being extremely chemically stable.

Virgin PTFE

Virgin PTFE (pure polytetrafluoroethylene) is resistant to nearly all chemicals, even at elevated temperatures up to 100°C. It is extremely non-reactive and resistant to acids, partly because of the strength of carbon-fluorine bonds, and is consequently often used in contact with reactive and corrosive chemicals. PTFE also has the best sliding and non-stick properties of all plastics. As the material is physiologically inert, even at high temperatures, it is ideal for contact with food. PTFE is best known for its use in Teflon® coating of frying pans.

Carbon-filled PTFE

The addition of a carbon filler to PTFE (polytetrafluoroethylene) gives the modified PTFE even more compressive strength and hardness, volume and surface resistivity and excellent sliding and wear properties. The filler is customised exactly to meet the customer’s requirements.

PVDF

PVDF (polyvinylidene fluoride) also offers high chemical resistance. It is primarily used in applications requiring the highest purity, strength and resistance to solvents, acids, bases and heat. Compared to other plastics, PVDF has an easier melt process, also allowing it to be injected, compression moulded or welded.
