Astralpool-waaier 1 HP II 50 Hz - 4405011450

Astralpool impeller 1 HP II 50 Hz 4405011450

The Astralpool impeller 1 HP II 50 Hz 4405011450 is the original replacement rotor for selected Astralpool pool pumps equipped with a
1 horsepower 50 hertz motor. This hydraulic component is responsible for generating the flow and pressure in the wet end of the pump, so
replacing a worn or damaged impeller is essential to restore stable, efficient filtration on compatible residential pool installations.

Function of the Astralpool impeller 1 HP II 50 Hz

Mounted directly on the motor shaft, the impeller rotates at high speed, drawing water in through the suction port and driving it towards
the diffuser and discharge outlet. The specific geometry of the Astralpool impeller 1 HP II 50 Hz 4405011450 is matched to the 50 hertz
motor speed and to the corresponding pump body, so the system can deliver the designed flow rate and head for a 1 HP configuration.

With the correct impeller installed and in good condition, the pump primes more easily, maintains strong suction at skimmers and drains
and circulates water reliably through the filter, heater and any treatment equipment connected to the circuit.

Ontwerp en bouw

The Astralpool impeller 1 HP II 50 Hz 4405011450 is moulded from high quality plastic suitable for long term use in treated pool water.
Its blades and hub are precisely shaped to work with the matching diffuser and pump housing, keeping internal clearances within the
tolerances defined by the manufacturer.

• Durable plastic body suitable for correctly balanced chlorinated or saltwater pools.
• Vane profile optimised for 1 HP 50 Hz operation on compatible Astralpool pumps.
• Centraal koppelstuk, ontworpen voor een veilige bevestiging op de motoras met behulp van het originele bevestigingssysteem.
• Balanced construction to support smooth, low vibration running when fitted correctly.

Compatibiliteit en typische toepassingen

This impeller is intended for use on specific Astralpool circulation pumps that list reference 4405011450 in their exploded view or spare
parts list for the 1 HP II 50 Hz version. It is typically used in small to medium residential pools where the pump provides daily
circulation through sand, glass or cartridge filters.

• Compatible with Astralpool pumps configured with a 1 HP 50 Hz motor that specify 4405011450.
• Suitable for in ground or above ground private pools within the corresponding performance range.
• Direct replacement for original impellers supplied with the same reference.

Before ordering, always check the identification label on your pump and compare with the official parts diagram to confirm that 4405011450
is the correct impeller reference for your model.

When to replace the impeller 4405011450

Even though the impeller is protected inside the housing, it operates at high speed and is exposed to fine abrasive particles, occasional
cavitation and normal mechanical stress. Over time, this can reduce flow and pressure or create noise and vibration.

• Loss of flow or filter pressure even with a clean prefilter basket and filter.
• Visible cracks, chips or broken sections on the impeller blades.
• Erosion or rounding of the vane edges and hub contact surfaces.
