CP offers pumps in three main materials: metal, plastic and ceramic. First, many different metals are available: stainless steels, duplex alloys, super duplex alloys, nickel alloys and titanium alloys. Second, in plastic, CP offers three options: PFA (lining), PTFE and PVDF. The third material is ceramic (lining).

Stainless Steels
CP offers all metallic magnetic coupled pumps as standard in stainless steel 1.4581 (316L). Stainless steels have many advantages over ordinary steels: they do not stain, corrode, or rust as easily. Stainless steels are often used where the properties of steels and a certain resistance to corrosion are required at the same time. The stainless steels have different grades and surfaces to optimally fit into the environment in which the steel will be used.

Duplex and Super Duplex Alloys
CP offers metallic magnetic coupled pumps in duplex and super duplex stainless steels. These steels have a ferrite and an austenitic structure at the same time. Duplex alloys have higher strength and better stress corrosion cracking resistance than most austenitic alloys and greater toughness than ferrite alloys, especially at low temperatures. Super Duplex steels are highly corrosion resistant ferrite-austenitic stainless steels because of their duplex metallographic structure. Super duplex stainless steels are premium alloys combining excellent mechanical properties with the highest levels of corrosion resistance.

Nickel Alloys
CP offers metallic magnetic coupled pumps in various nickel alloys. These alloys are non-ferrous metals with high strength and toughness, excellent corrosion resistance, and superior elevated temperature properties. Products differ in terms of composition, grade, shape, dimensions, and features. Commercially pure nickel, unalloyed nickel or very low alloy nickel contain only very small amounts of alloying elements. By contrast, nickel alloys contain significant amounts of alloying constituents.

Titanium Alloys
CP offers metallic magnetic coupled pumps in various titanium grades. These alloys are metallic materials which contain a mixture of titanium and other chemical elements. The different grades have dissimilar but very high tensile strengths and toughness even at extreme temperatures, light weights, extraordinary corrosion resistances, and abilities to withstand extreme temperatures.

Plastics
CP offers both magnetic coupled solid plastic pumps as well as magnetic coupled plastic-lined pumps, where all wetted surfaces are plastic-lined. Additionally, CP also offers plastic-lined pumps with its FuturaTef© double mechanical sealing system. Plastics are typically polymers of high molecular mass, and may contain other substances to improve performance. They are generally more corrosion resistant to many acids than most steels, or at least less expensive than equivalent pumps in special metallic alloys.

Ceramic
CP offers ceramic-lined pumps, where all wetted surfaces are ceramic-lined, including CP’s FuturaMik© double mechanical sealing system. Ceramic is an inorganic, non-metallic solid prepared by the action of heat and subsequent cooling. Ceramic materials may have a crystalline or partly crystalline structure, or may be amorphous (e.g., a glass). Because most common ceramics are crystalline, the definition of ceramic is often restricted to inorganic crystalline materials, as opposed to the non-crystalline glasses.
