EFI Industrial Centrifugal Pumps

Application

The Estampinox EFI pump is a stainless steel centrifugal pump ideal for the transfer of water and other low viscosity liquids. It is designed to cater for the needs of auxiliary services in the food-processing, chemical, pharmaceutical and wine-making industries

Estampinox EFI is a range of close-coupled centrifugal pumps. It is made of a cold-formed stainless steel casing, open impeller manufactured with stainless steel cold-formed plate or investment casting (according to model), mechanical seal, pump cover, lantern and shaft. Estampinox EFI centrifugal pump is provided with an internal single mechanical seal.
