About this wet end

This OEM wet end features dual 2" male buttress thread (MBT) connections and fits 48-frame pump configurations commonly found in residential spas and hot tubs. The robust construction ensures reliable water circulation and maintains optimal pressure throughout your spa system.

At Bubbles Supply, we guarantee this wet end will fit your Aqua-Flo FMXP2e pump exactly as designed.

Common symptoms this part fixes

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

  • Visible crack or leak at the volute or diffuser
  • Impeller worn or broken causing low flow
  • Seal failure resulting in water intrusion into motor
  • Grinding or cavitation noise from pump
  • Weak jet pressure despite motor running normally
  • Water leaking from wet end housing

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

Before you buy — quick checklist

  • Confirm your existing pump is an Aqua-Flo FMXP2e on a 48Y frame — check the motor label
  • Verify your plumbing connections are 2" MBT — measure or check existing union fittings before ordering
  • Confirm the 1.5HP rating on your current motor nameplate matches
  • Inspect the motor shaft before installing — if the shaft is corroded or damaged, the motor may need replacement too
  • Check whether your spa uses a single-speed or two-speed motor, as wet end compatibility may vary
  • Have a replacement shaft seal on hand before starting — reusing a worn seal after wet end service is a common cause of callbacks

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

Install difficulty: Medium — Some experience neededTypically 45–90 minutes
