The ATEX Pump Upgrade must be purchased with a compatible Transfer System, which will fill any size container with chemical concentrate or ready-to-use solution. The upgrade substitutes standard materials for all-EPDM hoses and an ATEX-approved FloJet air pump with Kalrez diaphragms, which are suitable for many solvent/alcohol applications. Transfer Systems draw chemical from bulk containers and dispense it into any other container through a 15 foot discharge hose and trigger gun.
