It is designed to support up to three 12mm outlets and has enough flow for a complete caravan fresh water system including a galley and shower.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I run three outlets from it?\u003c\/h3\u003e\n\u003cp\u003eYes. Jabsco specifies the pump for up to three 12mm outlets. Flow will be shared when multiple fixtures are open at the same time.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWill it provide better shower pressure than the standard PAR-MAX 3?\u003c\/h3\u003e\n\u003cp\u003eThe HD version can operate at a higher system pressure, with a 60 PSI cut-out compared with 40 PSI on the standard model. Whether that translates into noticeably stronger shower performance depends on the shower head, plumbing, filters, hot-water system and other restrictions.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWill I get 11.3LPM from the shower?\u003c\/h3\u003e\n\u003cp\u003eNot necessarily. The 11.3LPM specification is maximum pump flow. Actual shower flow will be lower once the pump is working against plumbing pressure and restrictions.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eIs 60 PSI too high for a caravan?\u003c\/h3\u003e\n\u003cp\u003eIt can be for some plumbing systems. Before installing the HD model, check the maximum pressure rating of every hose, fitting, filter, tap, mixer and hot-water appliance in the system.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWould I need a pressure reducer?\u003c\/h3\u003e\n\u003cp\u003ePossibly, if any component in your system is not rated for the pump's 60 PSI pressure. Whether a regulator is required depends on the plumbing and appliance pressure ratings and should be assessed before installation.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I use it with a caravan hot-water system?\u003c\/h3\u003e\n\u003cp\u003ePotentially, but this needs to be checked carefully because of the 60 PSI pressure capability. Confirm the maximum permitted inlet pressure of the hot-water service before connecting the pump.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDoes the pump turn on automatically when I open a tap?\u003c\/h3\u003e\n\u003cp\u003eYes. It is an automatic pressure pump designed to start as water is demanded and stop when system pressure reaches the 60 PSI cut-out point.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWhat is the cut-in pressure?\u003c\/h3\u003e\n\u003cp\u003eA specific cut-in pressure has not been provided for this HD model, so it should not be assumed from the specifications of another PAR-MAX version.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDo I need an accumulator tank?\u003c\/h3\u003e\n\u003cp\u003eNo. The built-in bypass is designed to reduce pulsation and cycling so that a separate accumulator tank is not required for normal operation.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWhat does the bypass valve do?\u003c\/h3\u003e\n\u003cp\u003eIt allows the pump to manage lower water demand more smoothly, reducing rapid on\/off cycling and pulsation when a tap is only partially open.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I mount the pump above the water tank?\u003c\/h3\u003e\n\u003cp\u003eYes, within the stated self-priming limit. The pump can self-prime up to approximately 2.4 metres \/ 8 feet.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDoes 2.4 metres mean the maximum hose length?\u003c\/h3\u003e\n\u003cp\u003eNo. The 2.4 metre figure refers to self-priming lift rather than total plumbing length. Longer hose runs are possible, but excessive restriction and air leaks can reduce performance.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan it run dry if my tank becomes empty?\u003c\/h3\u003e\n\u003cp\u003eYes. The HD version is specified as being capable of running dry for extended periods, which provides useful protection if the fresh water supply is lost.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I deliberately leave it running dry?\u003c\/h3\u003e\n\u003cp\u003eAlthough the pump is designed to tolerate extended dry operation, there is generally no benefit in running it without water unnecessarily. Dry-run capability is best treated as additional protection.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDoes it come with a filter?\u003c\/h3\u003e\n\u003cp\u003eYes. A 40-mesh plug-in inlet strainer is included in the box.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDoes it suit 12mm caravan water hose?\u003c\/h3\u003e\n\u003cp\u003eYes. Two 12mm barbed plug-in fittings are included for compatible fresh water hose.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eIs the HD model noisier because it is more powerful?\u003c\/h3\u003e\n\u003cp\u003eIt is specifically designed for quiet operation and includes soft vibration-dampening mounts plus an internal bypass to reduce cycling. Mounting surface and plumbing design still have a major effect on real-world noise.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I run it from a 12V lithium battery?\u003c\/h3\u003e\n\u003cp\u003eYes. The pump is designed for 12V DC operation and can be used with a suitable 12V lithium auxiliary system when correctly wired and fused.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I run it from an AGM battery?\u003c\/h3\u003e\n\u003cp\u003eYes. A suitable 12V AGM battery system can also operate the pump.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eHow many amps does it draw?\u003c\/h3\u003e\n\u003cp\u003eA current specification has not been provided here, so it should not be estimated when designing the electrical circuit. Confirm the exact current draw before selecting cable, fuse and switch ratings.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I use the HD model on 24V?\u003c\/h3\u003e\n\u003cp\u003eNo. This version is specified as 12V only and must be connected to a suitable 12V DC supply.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eIs this suitable for a boat?\u003c\/h3\u003e\n\u003cp\u003eYes. It is designed as a heavy-duty automatic fresh water pump for pleasure craft, with the stated application extending to boats approximately 9–10 metres in length.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWould this be a good replacement for an older Jabsco PAR-MAX pump?\u003c\/h3\u003e\n\u003cp\u003ePotentially. Compare the existing pump's voltage, flow, pressure, mounting space, plumbing connections and electrical requirements. The most important consideration when moving to this HD model is ensuring the existing plumbing and appliances can safely handle its 60 PSI pressure.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWhen should I choose the HD version instead of the normal PAR-MAX 3?\u003c\/h3\u003e\n\u003cp\u003eChoose the HD version where you specifically want the stronger four-chamber construction, 60 PSI pressure capability, heavier-duty motor assembly or extended dry-run capability. If your system is already well suited to 40 PSI, the standard PAR-MAX 3 may be sufficient.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWhat should I check before buying?\u003c\/h3\u003e\n\u003cp\u003eConfirm that your electrical system is 12V, check that the 11.3LPM flow is suitable for your outlets, make sure every plumbing component can tolerate the 60 PSI cut-out pressure, confirm the included 12mm fittings suit your hose and verify the pump's current draw and required fuse size before completing the electrical installation.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2 style=\"color: #dd1d1d;\"\u003e💧 HEAVY-DUTY JABSCO PERFORMANCE WITH UP TO 60 PSI PRESSURE\u003c\/h2\u003e\n\u003cp\u003eThe Jabsco PAR-MAX 3 HD takes the popular 11.3LPM PAR-MAX platform and strengthens it for more demanding fresh water systems.\u003c\/p\u003e\n\u003cp\u003eWith a quad four-chamber pump head, heavy-duty motor construction, 60 PSI pressure capability, self-priming to 2.4 metres, built-in pulsation control, extended dry-run capability and support for up to three outlets, it is a serious option for caravans, RVs and marine systems requiring stronger, smoother water pressure.\u003c\/p\u003e\n\u003cp\u003eFor installations where standard-duty pressure and construction are not enough, the PAR-MAX 3 HD delivers the same practical flow with a more robust, higher-pressure design.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"JABSCO","offers":[{"title":"Default Title","offer_id":45112647057656,"sku":"J20-208","price":414.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/9230\/4632\/files\/j0020-208_0_2d4f692e-fdd4-403b-8a40-fdde797d0d0e.jpg?v=1788492619","url":"https:\/\/www.homeof12volt.com.au\/products\/jabsco-par-max-3-hd-12v-fresh-water-pump-11-3lpm-60psi","provider":"Home of 12 Volt Northern","version":"1.0","type":"link"}
