TECHNICAL FAQ
Pentair Aurora 3550 Replacement Questions
Is the Pentair Aurora 3550 discontinued?
Yes. Pentair’s official Aurora 3550 product page labels the model Discontinued.
What replaces a discontinued Aurora 3550?
A corresponding G196 replacement route is reviewed from the existing 3550 group, pump size, drawing, hydraulic duty and construction.
Can the existing 3550 piping and installation be retained?
Nozzle, centerline, feet, shaft, coupling and baseplate relationships are checked against the selected size and approved drawing before order.
Which S, M, L or XL group should I select?
Use the group shown on the nameplate or drawing. Pentair publishes S, M/L and XL families; the local finder keeps M and L selectable for installed identification while engineering confirms the exact route.
What information is required for an Aurora 3550 replacement quote?
Provide the nameplate, group, pump size, GA drawing if available, duty point, liquid, temperature, material, seal and quantity.
