Actual shower performance will still depend on the shower head, hose, filters and water-heater restrictions.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWill I actually get 18.9LPM from my shower?\u003c\/h3\u003e\n\u003cp\u003eNot necessarily. The 18.9LPM figure represents maximum pump flow. Once the pump is operating against system pressure and plumbing resistance, actual outlet flow will be lower.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan several people use different taps at the same time?\u003c\/h3\u003e\n\u003cp\u003eMultiple fixtures can operate from the same pump, but the available flow will be divided between them. A system using four fixtures does not mean each individual fixture receives 18.9LPM.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDoes it automatically turn on when I open a tap?\u003c\/h3\u003e\n\u003cp\u003eYes. The built-in pressure switch provides automatic on-demand operation. Opening a tap causes system pressure to fall and starts the pump; closing the tap allows pressure to recover and the pump to switch off.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDo I need an accumulator tank?\u003c\/h3\u003e\n\u003cp\u003eNot normally. The pump is designed to operate without an accumulator tank and incorporates features intended to reduce cycling. An accumulator could still be considered for a specialised plumbing layout if required.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWhat does reduced cycling mean?\u003c\/h3\u003e\n\u003cp\u003eIt means the pump is designed to cope better with lower or changing water demand without constantly starting and stopping. This can improve water delivery and reduce repetitive pump noise.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eIs this better than an 11LPM pump?\u003c\/h3\u003e\n\u003cp\u003eIt is the stronger option when you need substantially higher flow or want to supply a larger number of fixtures. An 11LPM pump may be entirely adequate for a smaller caravan with a shower and one or two taps, while the 18.9LPM 51 Series is aimed at higher-demand systems.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWill a larger 18.9LPM pump use more water?\u003c\/h3\u003e\n\u003cp\u003eIt can if your fixtures allow the additional flow. A higher-capacity pump does not force every outlet to use maximum flow, but unrestricted taps and showers may consume water faster than they would with a smaller pump. This is worth considering in RVs with limited tank capacity.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eIs 4.8 Bar too much pressure for my caravan plumbing?\u003c\/h3\u003e\n\u003cp\u003eIt may be for some components. Before installing the pump, check the maximum pressure rating of all hoses, fittings, filters, taps, water heaters and other appliances in the plumbing system.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I use it with a hot-water service?\u003c\/h3\u003e\n\u003cp\u003ePotentially, provided the water heater is compatible with the pump's pressure and flow characteristics. Check the hot-water system manufacturer's maximum inlet pressure before installation.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I use it with a water filter?\u003c\/h3\u003e\n\u003cp\u003eYes, provided the filtration system is correctly sized for the required flow and pressure. Restrictive filters can reduce actual water delivery.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I mount the pump above the water tank?\u003c\/h3\u003e\n\u003cp\u003eThe pump is self-priming, which allows more flexible positioning relative to the tank. However, a maximum self-priming lift has not been provided here, so confirm the exact model specification if the pump will be installed significantly above the water source.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan it run dry if my water tank runs empty?\u003c\/h3\u003e\n\u003cp\u003eYes. Dry-run safety is one of the stated features. This provides useful protection if water is temporarily unavailable, although unnecessary dry operation should still be avoided.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I use it with salt water?\u003c\/h3\u003e\n\u003cp\u003eYes. The pump is stated as suitable for both fresh and salt-water applications.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eIs it waterproof?\u003c\/h3\u003e\n\u003cp\u003eThe pump is described as having good sealing and water- and dust-resistant characteristics, but no specific IP rating has been provided. It should therefore not automatically be treated as fully waterproof or suitable for unrestricted external exposure.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I run it from a 12V caravan battery?\u003c\/h3\u003e\n\u003cp\u003eNo. This listing is specifically for the 24V version. The pump requires a suitable 24V DC electrical supply.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I run it from two 12V batteries?\u003c\/h3\u003e\n\u003cp\u003ePotentially, if the two suitable 12V batteries are correctly configured as a 24V bank and the complete electrical system is designed for that arrangement. Two batteries connected in parallel remain a 12V system and would not provide the required voltage.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWhat current does the pump draw?\u003c\/h3\u003e\n\u003cp\u003eA current rating has not been provided here, so it should not be estimated for electrical system design. Confirm the specification for the exact 24V SEAFLO 51 Series model before selecting cable, fuse or switch ratings.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I use this for agricultural spraying?\u003c\/h3\u003e\n\u003cp\u003eYes. Agricultural spraying is one of the listed applications, provided the pressure, flow and pumped liquid are compatible with the system.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I use it for chemical spraying?\u003c\/h3\u003e\n\u003cp\u003eNo general chemical compatibility information has been provided. Do not assume that the diaphragm, valves or pump housing are compatible with a particular chemical without checking the exact fluid against SEAFLO's specifications.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I use it for drinking water?\u003c\/h3\u003e\n\u003cp\u003eThe pump is described for water systems including RVs, boats and beverage-processing applications, but no specific potable-water certification has been stated here. If certification is required for your installation, confirm it for the exact model before purchase.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWhat should I check before buying?\u003c\/h3\u003e\n\u003cp\u003eConfirm that your system is 24V, make sure you actually need the high 18.9LPM flow capacity, check that your plumbing and appliances can handle pressure up to 4.8 Bar, determine how many fixtures will operate simultaneously and verify the exact port size, current draw, fuse requirement and installation dimensions before completing the installation.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2 style=\"color: #dd1d1d;\"\u003e💦 HIGH-VOLUME 24V WATER PRESSURE FOR SERIOUS SYSTEMS\u003c\/h2\u003e\n\u003cp\u003eThe SEAFLO 51 Series is designed for water systems that have moved beyond the capabilities of a basic caravan or single-outlet pressure pump.\u003c\/p\u003e\n\u003cp\u003eWith up to 18.9LPM flow, 4.8 Bar pressure capability, a large five-chamber diaphragm, automatic pressure control, self-priming operation, reduced cycling and support for up to four fixtures, it offers serious water-delivery performance in a versatile 24V package.\u003c\/p\u003e\n\u003cp\u003eFor larger RVs, boats, remote cabins, agricultural systems or other high-demand installations, the SEAFLO 51 Series provides the flow and flexibility needed to run a more capable water system.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Home of 12 Volt Northern","offers":[{"title":"Default Title","offer_id":46511117631736,"sku":"SFDP2-24","price":259.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/9230\/4632\/files\/Screenshot2025-06-05123358.jpg?v=1749092735","url":"https:\/\/www.homeof12volt.com.au\/products\/seaflo-51-series-24v-water-pump-18-9lpm-4-8-bar","provider":"Home of 12 Volt Northern","version":"1.0","type":"link"}
