AstralPool – Threaded Lid Collar for Colusa Pump

This is the genuine AstralPool threaded lid collar for the Colusa self-priming pool pump. Positioned as part 1 in the official Fluidra exploded view, it is the structural ring that threads onto the pre-filter housing to lock the transparent pre-filter lid securely in place. Replacing a worn or damaged collar restores a proper watertight seal and safe access to the pre-filter basket.

Compatibilità

This collar is designed specifically for the AstralPool Colusa pump family (parent SKU 70579). The Colusa range covers models from 0.5 HP to 3 HP in both single-phase and three-phase configurations, making this part relevant to a wide installed base of domestic and commercial pool pumps across Europe.

Perché l'originale conta

As an OEM component sourced directly from Fluidra, this collar is manufactured to the exact thread pitch and tolerances of the Colusa pre-filter housing. A precise fit is essential: an ill-fitting or aftermarket collar can result in air ingress, loss of prime, or pre-filter leaks that compromise pump performance and longevity.

Installazione

Switch off and isolate the pump before attempting any maintenance. Unscrew and remove the existing collar by turning it counter-clockwise, then fit the new collar by hand, threading it clockwise onto the pre-filter body until snug. No special tools are required, but always inspect the lid O-ring at the same time and replace it if worn to ensure a leak-free reassembly.
