Built for 2.0HP motors with a 56-frame configuration, this OEM wet end features dual 2" MBT (male buttress thread) connections for reliable plumbing integration. The genuine Aqua-Flo by Gecko construction ensures optimal hydraulic performance and long-lasting durability in your spa's circulation system.

Common symptoms this part fixes

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

  • Cracked or leaking pump housing
  • Visible damage to volute or impeller housing
  • Low water flow caused by worn impeller or damaged wet end
  • Water leaking from pump body at seal plate
  • Noisy pump operation due to internal wet end wear
  • Pump moving water but pressure is significantly reduced

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 your plumbing connections are 2" MBT (male buttress thread) — do not assume based on pipe diameter alone
  • Confirm your motor is rated for 2.0HP and is in working condition before replacing only the wet end
  • Inspect the motor shaft seal separately — the seal is not included and should be replaced at the same time
  • Check that your existing motor's face plate matches the 56Y frame bolt pattern before ordering

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