About this wet end

This Vico 48Y Frame wet end delivers reliable performance for 1.5HP spa pumps requiring 1-1/2" MBT inlet and outlet connections. Designed specifically for Ultima series applications, this OEM-quality wet end features the robust 48Y frame configuration that ensures proper alignment and seal integrity in your spa's circulation system.

Built to Vico's exacting standards, this wet end replacement guarantees an exact fit for compatible spa pumps while maintaining optimal flow rates and pressure. Bubbles Supply backs every wet end with our 1-year warranty and same-day shipping to get your spa running fast. Before installation, verify your existing pump's frame size and connection measurements match the 48Y frame and 1-1/2" MBT specifications to ensure proper fitment.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Pump motor runs but no water flow
  • Impeller cracked or broken
  • Wet end leaking at seal plate
  • Low flow or weak jet pressure
  • Grinding or cavitation noise from pump
  • Wet end housing cracked or damaged

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your existing pump is a 48Y frame — do not assume based on HP alone
  • Verify both inlet and outlet connections are 1-1/2" MBT before ordering
  • Check the label on your current pump motor to confirm it is a Vico Ultima series
  • Inspect your motor shaft to confirm it is reusable — this is a wet end only, motor not included
  • Measure your existing seal plate and impeller to cross-reference fit before pulling the old wet end

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
