What is Electro-Polished?

Electro Polished High Purity Pumps  

Electro-Polished (EP) is a process in which metal is removed from a product.  This is done with the passage of an electric current while the product is submerged into a specially blended chemical solution. This process removes the surface imperfections, such as impurities, burrs and other defects, allowing the benefits for ultra-cleaning, micro-finishing and corrosion protection environments. 

Yamada's EP Series pumps are specifically designed for transferring ultra high-purity solvents and other non-corrosive liquids compatible with 316 Stainless Steel.

Pumps include 20Ra Electro Polished 316 Stainless Steel wetted components, PTFE elastomers and FNPT liquid ports.
