About this wet end

This OEM Aqua-Flo by Gecko wet end assembly is designed for 3.0HP spa pumps with 56Y frame configuration and dual 2" MBT (male buttress thread) connections. Compatible with Aqua-Flo FMXP2e pump series, this genuine replacement part restores proper water circulation in your hot tub or spa system.

Engineered to OEM specifications, this wet end features the exact threading and hydraulic design your spa requires for optimal performance. At Bubbles Supply, we guarantee an exact fit with same-day shipping on orders placed before our cutoff time, plus every wet end comes with our comprehensive 1-year warranty. Verify your existing pump's frame size and connection type before ordering—both suction and discharge ports should match the 2" MBT threading shown on your current wet end assembly.

Common symptoms this part fixes

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

  • Weak or no water flow from jets
  • Pump runs but water pressure is low
  • Wet end leaking at impeller housing
  • Loud grinding or cavitation noise from pump
  • Impeller visibly cracked or damaged
  • Water bypassing pump due to worn 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 with a 56Y frame — check the label on the motor body
  • Verify both suction and discharge ports are 2" MBT threading before ordering
  • Do not order based on pump HP alone — frame size and port type must also match
  • Inspect the motor shaft before installing the new wet end — a worn or corroded shaft will damage the new impeller seal
  • Confirm your plumbing unions are compatible with 2" MBT fittings
  • Check whether you need just the wet end or the full pump assembly — the motor is sold separately

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

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