\nThe Astralpool impeller 1 HP II 50 Hz 4405011450 is the original replacement rotor for selected Astralpool pool pumps equipped with a
\n1 horsepower 50 hertz motor. This hydraulic component is responsible for generating the flow and pressure in the wet end of the pump, so
\nreplacing a worn or damaged impeller is essential to restore stable, efficient filtration on compatible residential pool installations.\n<\/p>\n
\nMounted directly on the motor shaft, the impeller rotates at high speed, drawing water in through the suction port and driving it towards
\nthe diffuser and discharge outlet. The specific geometry of the Astralpool impeller 1 HP II 50 Hz 4405011450 is matched to the 50 hertz
\nmotor speed and to the corresponding pump body, so the system can deliver the designed flow rate and head for a 1 HP configuration.\n<\/p>\n
\nWith the correct impeller installed and in good condition, the pump primes more easily, maintains strong suction at skimmers and drains
\nand circulates water reliably through the filter, heater and any treatment equipment connected to the circuit.\n<\/p>\n
\nThe Astralpool impeller 1 HP II 50 Hz 4405011450 is moulded from high quality plastic suitable for long term use in treated pool water.
\nIts blades and hub are precisely shaped to work with the matching diffuser and pump housing, keeping internal clearances within the
\ntolerances defined by the manufacturer.\n<\/p>\n
\nThis impeller is intended for use on specific Astralpool circulation pumps that list reference 4405011450 in their exploded view or spare
\nparts list for the 1 HP II 50 Hz version. It is typically used in small to medium residential pools where the pump provides daily
\ncirculation through sand, glass or cartridge filters.\n<\/p>\n
