AstralPool - Astramax Pump Impeller 1 HP – 50 Hz - 4405020116

AstralPool – Astramax Pump Impeller 1 HP – 50 Hz

This is the genuine AstralPool replacement impeller for the Astramax EU Horizontal Outlet SS 1 HP II pump (parent SKU 19930), rated for 50 Hz mains frequency as used throughout Europe. The impeller is the core hydraulic component responsible for moving water through the pump, and a worn or damaged impeller directly reduces filtration flow and efficiency. Replacing it with this OEM part restores the pump to its original performance specification.

Compatibility

This impeller is engineered exclusively for the AstralPool Astramax EU Horizontal Outlet SS 1 HP II pump (SKU 19930). It occupies position 13 in the official Fluidra/AstralPool exploded-view diagram for this pump. Always cross-reference your pump’s model number before ordering to ensure an exact fit — this part is not interchangeable with 60 Hz variants or other Astramax power ratings.

Why Genuine Matters

OEM impellers are precision-balanced and manufactured to AstralPool’s hydraulic tolerances, ensuring correct flow rate, minimal vibration, and a proper seal against the diffuser. Aftermarket alternatives may differ dimensionally, causing premature wear to the mechanical seal and pump body. As a genuine Fluidra/AstralPool spare part, this impeller carries the manufacturer’s quality assurance and is designed for a direct, no-modification fit.

Installation

Replacing the impeller requires draining the pump, removing the pump housing bolts, and carefully extracting the existing impeller from the motor shaft. The task is straightforward for a qualified pool technician but is recommended to be carried out by a professional to avoid damage to the mechanical seal or motor shaft during reassembly. Always isolate mains power before beginning any work on the pump.
