Back in December 1950, Vanton were able to develop a very small and compact revolutionary plastic pump which is able to be used in conjunction with the first heart-lung device.
The design would limit fluid contact to only two non-metallic parts: these are a plastic body block and a flexible liner. This was the birth of the Flex-i-liner® which was a seal-less self-priming rotary pump which has now become the industry standard for handling corrosive, abrasive and viscous fluids as well as those that must be transferred free of product contamination, or with the highest levels of hygiene attainable.
The wet end components of every single Vanton pump product are all made from corrosion and abrasion resistant engineered plastics such as, polypropylene (PP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), and polyvinylidene fluoride (PVDF). Completely inert, these thermoplastics are all impervious to acids, caustics, salts, solvents, and other aggressive, abrasive chemicals which are able to attack pumps which are made of metals, plastic or rubber lined metals, and fiberglass reinforced plastics.
Metals (including stainless steel, Hastelloy® and other high alloys) all have accepted annual rates of corrosion whereas Vanton's range of chemically inert thermoplastic components do not. As a result, Vanton pumps are able to provide a long, trouble-free service life and are able to prevent the contamination of other reagent-grade chemicals and other ultrapure fluids.
