Our Solution
As Queensland’s sole authorised PSG Dover importer and distributor of Wilden Double Diaphragm pumps, Griswold & System One Centrifugal pumps, and Abaque Peristaltic pumps, Dowdens were able to select a specialised Griswold pump made from Alloy 20 for use in the Evacuation Pumps.
Alloy 20 is a nickel-chromium-molybdenum stainless steel alloy developed for applications involving sulfuric acid. Alloy 20 resists pitting and chloride ion corrosion, and its copper content protects it from sulfuric acid.
