Astralpool Impeller Ecombie FX340 CTX400 40060G

Astralpool Impeller CTX 400 / FX340 / CX320 Ecombie 40060G

This is the genuine Astralpool impeller, part number 40060G, the 1.5HP impeller for the CTX 400, FX340 and CX320 Ecombie pumps. CTX impellers are sized to the model number and are not interchangeable across the range — the pump body looks identical from CTX 180 through CTX 610, but each takes its own impeller.

Supersession: 40060U Is No Longer Used

Earlier CTX 400 pumps were built with impeller 40060U. Astralpool has since consolidated the CTX 400 onto 40060G, the 1.5HP impeller shared with the FX340 and CX320 Ecombie. If your old impeller or parts list shows 40060U, this is the part you now order.

The CTX Impeller Rule (rev. CTX-1.0)

1. Read the model number on the pump badge — the three digits after CTX or CX are what matter. 180, 280, 360, 400, 500 and 610 each take a different impeller.
2. Check the impeller you removed for a moulded part number. If it reads 40060U, order this part as its replacement.
3. If the badge says Viron rather than CTX or CX, stop. Viron XT pumps take 40060X (P320) or 40060Z (P520).
4. If you cannot read the badge, send us a photo of the pump and the old impeller. We would rather identify it for you than have it come back.

Symptoms of a Failed or Worn Impeller

• Motor runs at normal speed and normal noise, but flow and filter pressure are both down
• Pump takes far longer to prime, or will not hold prime, with no air leak found on the suction side
• Grinding, rattling or a rhythmic knock from the wet end
• Pump humming but not turning — usually debris jammed in the impeller, often after the hair and lint basket has split
• Visible debris packed into the vane passages, or vane tips worn back and rounded
• Cracked or spun hub after the pump has run dry

When to Replace

Replace the impeller when the vanes are worn, chipped or cracked, when the hub has spun, or when the pump has run dry and the plastic has distorted. Blocked vanes can often be cleared rather than replaced — check that first. Because the mechanical seal is disturbed whenever the impeller comes off, we recommend fitting a new mechanical seal at the same time rather than reusing a seal whose faces have been separated.

Frequently Asked Questions

My old impeller is marked 40060U — is this the right replacement?
Yes. The CTX 400 has been consolidated onto 40060G, the 1.5HP impeller shared with the FX340 and CX320 Ecombie.

Will this fit a CTX 360 or CTX 500?
No. Each CTX model takes its own impeller. The CTX 360 uses 40060F and the CTX 500 uses 40060V.

Can I fit a larger impeller to get more flow?
No. The impeller is sized to the motor. A larger impeller on a smaller motor draws excessive current and will shorten the motor's life.

Do I need a new mechanical seal when I replace the impeller?
We recommend it. The seal is split apart as soon as the impeller comes off, and reused seal faces are the most common cause of a leak after an impeller change. These pumps use the BX / TX / CX / E / CTX seal.

Is this a genuine Astralpool part?
Yes. We are an authorised Astralpool and Fluidra dealer and warranty agent.
