Fitting this tank ahead of the outlet turns that surge into a steady flow, and because its internal diaphragm can be opened up for a check or a repair, it stays a serviceable part rather than something you throw away once it's charged and connected into the line.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInline diaphragm tank\u003c\/strong\u003e – smooths pulsing pump delivery into a steadier flow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorks across pump brands\u003c\/strong\u003e – suits Fiamma pumps as well as other common makes such as Shurflo and Flojet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemovable service diaphragm\u003c\/strong\u003e – opens up for a repair or check instead of a full replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-charged and adjustable\u003c\/strong\u003e – arrives ready to fit, with a valve for recharging using a standard compressor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCuts hammering in the line\u003c\/strong\u003e – eases strain on the pump and boiler over time\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIdeal For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaravan and motorhome owners with a noisy pump\u003c\/strong\u003e wanting a steadier flow at the tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOwners running an older pump setup\u003c\/strong\u003e looking for an add-on that reduces surge and wear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnyone fitting a new water pump\u003c\/strong\u003e who wants to protect it and the boiler from day one\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eLocal Support from 4Matt Campers\u003c\/h2\u003e\u003cp\u003eOur \u003cstrong\u003eCape Town\u003c\/strong\u003e team can help you match this tank to your existing pump before you order.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Fiamma\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 02478-02-\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fiamma pumps and other common brands\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecharge Pressure:\u003c\/strong\u003e 0.9 bar (13 psi)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eOptional Fitment \/ Upgrade Notes\u003c\/h2\u003e\u003cp\u003eBefore you order, check:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWhich pump you're running it with, since it suits Fiamma pumps and other brands such as Shurflo and Flojet\u003c\/li\u003e\n\u003cli\u003eWhether you'd like us to confirm the precharge suits your specific pump model\u003c\/li\u003e\n\u003cli\u003eThat you have access to a compressor if you ever need to adjust the charge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eComplete Your Setup\u003c\/h2\u003e\u003cp\u003eTeam it with one of our \u003ca href=\"\/collections\/caravan-water-heating-geysers\"\u003ewater system parts\u003c\/a\u003e, browse more \u003ca href=\"\/collections\/fiamma\"\u003eFiamma\u003c\/a\u003e spares, or see the full range of \u003ca href=\"\/collections\/accessories\"\u003ecamping accessories\u003c\/a\u003e.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWill this fit my water pump?\u003c\/strong\u003e\u003cbr\u003eIt's designed to suit Fiamma pumps and other common brands, such as Shurflo and Flojet, so check your model or ask us to confirm before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes it need a power connection?\u003c\/strong\u003e\u003cbr\u003eNo, it's a passive plumbing part fitted into the water line near the pump, not a powered component.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be repaired instead of replaced?\u003c\/strong\u003e\u003cbr\u003eYes, the internal diaphragm can be opened up for a check or a repair.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat pressure does it come charged to?\u003c\/strong\u003e\u003cbr\u003eIt arrives precharged at 0.9 bar (13 psi), and can be recharged with the correct valve and a standard compressor.\u003c\/p\u003e","brand":"Fiamma","offers":[{"title":"Default Title","offer_id":49146850148537,"sku":"02478-02-","price":1075.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0764\/4587\/6409\/files\/A20-2-960x640.jpg?v=1789449200","url":"https:\/\/www.4mattcampers.co.za\/products\/fiamma-a20-expansion-tank","provider":"4Matt Campers","version":"1.0","type":"link"}
