AstralPool - Exactus Dosing Pump Complete Head Assembly - 4408031205

AstralPool – Exactus Dosing Pump Complete Head Assembly

This is the genuine AstralPool replacement complete pump head assembly (position 10 in the official Fluidra exploded view) for the Exactus Manual Analogue Dosing Pump (MA/AD). The pump head is the hydraulic heart of the dosing unit — it houses the diaphragm chamber and the inlet/outlet valve connections through which pool treatment chemicals such as chlorine, acids, or alkalis are precisely metered into the water circuit. Replacing a worn or damaged head restores full dosing accuracy without the cost of fitting an entirely new pump.

Compatibility

This head assembly is designed for the AstralPool Exactus Manual Analogue Pump MA/AD (parent SKU PEX2303101AS). It corresponds to position 10 in the official Fluidra exploded-view diagram. Always cross-reference your pump’s model label and the exploded-view diagram before ordering to confirm fitment.

Why Genuine Matters

Manufactured to AstralPool factory standards, this genuine OEM head assembly is made from chemically resistant materials — polypropylene body with Viton and PTFE (Teflon) components — ensuring safe, long-lasting contact with aggressive dosing liquids. A genuine part guarantees dimensional precision for a leak-free seal and preserves any remaining warranty on your pump. Non-OEM substitutes may compromise dosing accuracy or chemical containment.

Installation

Replacing the pump head involves removing the existing head, inspecting and replacing any associated seals, and fitting the new assembly in accordance with the Exactus series maintenance manual. The procedure is straightforward for qualified pool technicians or installers experienced with diaphragm metering pumps. Note that tubing, connectors, and supplementary seals are sold separately and should be inspected at the same time.
