AstralPool – Complete Injector Valve Assembly for Exactus Dosing Pump

This is the genuine AstralPool replacement injector valve assembly (part 4408030121) for the Exactus Manual Analogue dosing pump range. It serves a dual function: injecting liquid chemical treatment — such as pH corrector or liquid chlorine — into the pool water line, while simultaneously acting as a non-return valve to prevent any backflow of liquid towards the dosing pump. It corresponds to position 19 in the official Fluidra exploded-view diagram.

Compatibility

This assembly is designed specifically for the AstralPool Exactus Manual Analogue Pump Ma/Ad (parent SKU PEX2303101AS). Always cross-reference with the official Fluidra exploded-view diagram for your pump model before ordering to confirm fitment.

How It Works

The injector valve assembly installs at the pump’s discharge outlet and precisely meters chemical fluid into the pool circulation line. Its integrated non-return mechanism stops backflow from re-entering the pump body, protecting the diaphragm and internal components from chemical contamination or pressure surges.

Why Genuine Matters

As an OEM AstralPool part, this valve assembly is manufactured to exact tolerances for the Exactus pump head — ensuring a secure, leak-free seal and long service life with the polypropylene and FPM (Viton) contact materials the pump is designed for. Aftermarket alternatives may not match the thread specification or valve geometry, risking chemical leaks or pump damage.
