Frequently Asked Questions
Find answers to common questions about our metallic AODD pumps.
What is the difference between SS304 and SS316L?
SS316L contains molybdenum which provides better corrosion resistance, particularly against chlorides and acidic environments. SS316L is recommended for marine, chemical, and pharmaceutical applications where superior corrosion resistance is required.
When should I choose Super Duplex material?
Super Duplex is recommended for extreme environments including seawater applications, sour gas service, high chloride environments, and aggressive chemical processing. It offers superior strength and corrosion resistance compared to standard stainless steel grades.
Are these pumps ATEX certified?
Select metallic AODD pump models can be configured for hazardous-area service. Final suitability depends on the pump configuration, grounding, fluid, site classification and required certification.
What fluids can metallic AODD pumps handle?
Metallic AODD pumps can handle solvents, oils, paints, inks, wastewater, sludge, slurry, mild chemicals, hydrocarbons and compatible process liquids when wetted materials are selected correctly.
Can these pumps run dry without damage?
Yes, AODD pumps are dry-run tolerant because they use diaphragms and check valves rather than rotating mechanical seals. Operating conditions should still be reviewed for best diaphragm life.
