Yes. The SuperFit II is a direct retrofit replacement for all Astral CTX MKII models, as well as the older Hurlcon CX and TX pumps which share very similar plumbing configurations. Will the SuperFit II fit my existing plumbing and base? In most cases, yes. The SuperFit II features a uni-bracket mounting base that adapts to both 48- and 56-frame motors, and its plumbing footprint is compatible with CTX, CX, TX, Davey StarFlo DSF, Reltech Aquatight, and Sensapool SR installations. Madimack InverFLOW Plus installations are usually compatible with minimal changes. Is the SuperFit II energy efficient? The SuperFit II uses full-flow hydraulics to deliver greater water flow at a lower cost of operation compared to older medium-head pumps. Its heavy-duty motor with airflow ventilation also runs quieter and cooler, extending motor life. How often does the SuperFit II basket need cleaning? The large 155 cubic-inch strainer basket extends the time between cleanings compared to standard pumps, reducing maintenance frequency for pool owners.
