FAQs
What makes Viton seals beneficial in the Oberdorfer 172B-S17 pump?
Viton seals provide improved resistance to high temperatures, chemicals, oils, and aggressive fluids compared to standard rubber seals, helping extend pump service life in demanding applications.
Is the Oberdorfer 172B-S17 self-priming?
No. The pump is not self-priming and is typically installed in flooded suction systems where liquid naturally feeds into the pump inlet.
Can this pump be used for industrial applications outside marine environments?
Yes. The 172B-S17 is widely used in industrial circulation, commercial liquid transfer, HVAC systems, cooling systems, and OEM fluid handling applications.
What types of liquids can this pump handle?
The pump is suitable for water, light oils, water-based solutions, and select mild solvents that are compatible with bronze and Viton seal materials.
Does the pump support continuous-duty operation?
Yes. Its rugged bronze housing, centrifugal design, and corrosion-resistant internal components make it suitable for continuous-duty circulation systems.
Why is bronze construction important in centrifugal pumps?
Bronze offers strong corrosion resistance, durability, and long operational life, especially in environments involving moisture, water circulation, and chemically sensitive liquids.
