AstralPool - V-Ring Shaft Seals for Alaska Max Pump 1.5 HP – 3 HP - 4405010159

AstralPool – V-Ring Shaft Seals for Alaska Max Pump 1.5 HP – 3 HP

This is the genuine AstralPool set of V-ring shaft seals designed specifically for the AstralPool Alaska Max pool pump in 1.5 HP through 3 HP ratings. V-ring seals are all-rubber axial rotary seals that stretch onto the motor shaft and rotate with it, pressing their flexible lip against a stationary counterface to exclude contaminants and protect the pump’s internal components. Replacing worn V-rings promptly keeps the motor bearings and mechanical seal in optimal condition, extending the overall service life of your pump.

Kompatibilität

These V-rings are the OEM replacement for position 23 in the official Fluidra exploded-view diagram for the AstralPool Alaska Max pump (parent SKU 41604). They are specified for Alaska Max models rated at 1.5 HP and 3 HP — including both single-phase and three-phase variants in that power range. Always confirm your pump’s model code before ordering to ensure an exact fit.

How V-Ring Seals Work

A V-ring seal mounts directly on the rotating shaft using its own elastic tension, requiring no housing or metal casing. As the shaft spins, the tapered lip maintains a light axial contact against a stationary counterface, acting as a centrifugal flinger that expels water, dirt, and debris away from the bearing area. This simple yet effective mechanism shields the pump’s radial shaft seal and bearings from contamination, helping prevent premature wear and unexpected downtime.

Why Genuine Parts Matter

Genuine AstralPool V-rings are manufactured to the exact material specification and dimensional tolerances required for Alaska Max pumps, ensuring a secure interference fit on the shaft and correct axial preload on the sealing lip. Aftermarket substitutes may differ in elastomer compound or geometry, leading to inadequate sealing or accelerated failure. Using authentic AstralPool spare parts also keeps your equipment aligned with manufacturer service recommendations.
