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.<\/p>\n
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.<\/p>\n
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.<\/p>\n
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.<\/p>","protected":false},"excerpt":{"rendered":"
