• Authorised AstralPool / Fluidra dealer so you get genuine product, proper warranty support, and the correct Australian-supplied model.
• Direct retrofit for many older Hurlcon / Astral CX, TX and CTX pumps, making replacement much easier when your old pump has failed.

Alternative retrofit options using the same plumbing footprint:

• Sensapool SR
• Madimack Inverflow Plus F300i

Important sizing note: older Hurlcon CX and some early pump ranges often used inflated or less-helpful horsepower comparisons, so HP alone is not the best way to size a replacement. In practice, replacements are better matched by flow rate, head pressure, plumbing layout, and what the pump is actually running. That is why the CTX 280C is commonly used as the retrofit choice for older CX / TX pumps.

The AstralPool CTX series has been one of the most proven Australian pump ranges for years. Astral states the CTX pump is built from high-quality materials and components, designed to produce greater efficiency, reduced noise, and dependable high-pressure performance. It is specifically promoted for in-floor cleaning systems, spa jets, and demanding applications, which is exactly why these pumps have such a strong reputation in the field. :contentReference[oaicite:1]{index=1}

If you are replacing an older Hurlcon CX 240, TX 1.0, or earlier CTX 280, the CTX 280C is usually the cleanest genuine replacement because it keeps you within the same well-known Astral / Hurlcon pump family while updating to the latest version. Multiple Australian pool retailers also describe the CTX range as a retrofit for older CX and TX models, reinforcing how commonly these pumps are used as direct replacements. :contentReference[oaicite:2]{index=2}
