With a 3-litre capacity and durable steel construction, this pressure tank helps reduce pump cycling, maintain consistent pressure, and extend the life of connected pumps in pressure boosting and water transfer systems.\u003c\/p\u003e\n\u003cp\u003eThe tank is constructed with a polypropylene internal liner and a high-grade butyl diaphragm that separates air and water, creating a closed system that maintains stable pressure while preventing contamination or bacterial growth in drinking water applications. A corrosion-resistant epoxy coated exterior and 304 stainless steel water connection provide durability and long service life in demanding water system environments.\u003c\/p\u003e\n\u003cp\u003eDesigned for reliable operation, the SPT-003 pressure vessel is rated for a maximum working pressure of 10 bar and liquid temperatures up to 90°C. The tank is factory tested to ensure structural integrity and includes a leak-free O-ring sealed air valve cap for easy pressure adjustment and maintenance-free operation. Suitable for use with booster pumps, pressure systems, and water transfer setups, this compact vessel is ideal for installations where space is limited but pressure stability is required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3 litre pressure vessel capacity\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMaximum working pressure: 10 bar\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMaximum working temperature: 90°C\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePolypropylene internal liner for durability\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHigh grade butyl diaphragm for reliable pressure control\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCorrosion resistant baked epoxy coated steel tank\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e304 stainless steel water connection\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLeak-free O-ring sealed air valve cap\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e100% pressure tested construction\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e25mm (1\") BSP connection\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDesigned for water pressure boosting and pump systems\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pumpmaster","offers":[{"title":"Default Title","offer_id":50536875131127,"sku":"SPT-003","price":116.44,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/PumpmasterAquafosSPT-0033LSteelPressureVesselTank25mmConnection_29162f30-9cdd-4c44-b748-0ccb943beee5.png?v=1772678314","url":"https:\/\/foundationpumps.com.au\/products\/pumpmaster-aquafos-spt-003-3l-steel-pressure-vessel-tank-25mm-connection","provider":"Foundation Pumps","version":"1.0","type":"link"}
