🚿 IDEAL FOR CARAVAN & RV WATER SYSTEMS

The FLOJET 11LPM pump is designed for systems that need more than basic single-tap water delivery.

It is particularly well suited to applications such as:

• 🚐 Caravan fresh water systems
• 🏕️ Camper trailer plumbing
• 🚿 Showers
• 🚰 Kitchen sinks
• 🚰 Bathroom basins
• 🚤 Compatible marine fresh water systems
• 🚙 4WD touring setups

With capacity for up to three outlets, it is a practical choice for caravans and RVs where a shower, kitchen tap and basin may all be connected to the same fresh water pump.

---

⚙️ AUTOMATIC ON-DEMAND WATER PRESSURE

The built-in pressure switch allows the pump to operate automatically as water is required.

When a tap is opened, system pressure falls and the pump starts.

When the tap is closed, pressure builds until the pressure switch stops the pump.

This provides normal household-style operation without manually switching the pump on and off every time water is used.

---

🔄 BUILT-IN BYPASS FOR SMOOTHER WATER DELIVERY

The FLOJET incorporates an internal bypass valve designed to reduce water pulsation and unnecessary rapid cycling.

This can make a noticeable difference when:

• A tap is only partially opened
• A low-flow outlet is being used
• Water demand changes frequently
• The system would otherwise cause the pump to repeatedly start and stop

The bypass helps the pump manage smaller flow demands more smoothly instead of immediately switching between full operation and shut-off.

---

💨 DO I NEED AN ACCUMULATOR TANK?

Because the pump incorporates a built-in bypass, the need for a separate accumulator tank may be reduced.

An accumulator can still be useful in some installations for additional smoothing, reduced cycling or stored pressure, but it should not automatically be considered necessary for every FLOJET installation.

---

💧 SELF-PRIMING TO 2.5 METRES

The pump is capable of self-priming to approximately 2.5 metres.

This means it can be mounted above the fresh water tank within its stated priming capability, giving significantly more installation flexibility than a non-self-priming centrifugal pump.

⚠️ Suction hose restrictions, air leaks, excessive fittings and long pipe runs can reduce real-world priming performance. Keep the inlet plumbing airtight and as unrestricted as practical.

---

💦 11LPM / 2.9GPM FLOW CAPACITY

The pump is rated at up to 11 litres per minute / 2.9 gallons per minute.

This gives it enough capacity for substantially stronger fresh water delivery than smaller 3–4LPM pumps.

⚠️ IMPORTANT: The 11LPM rating should not be interpreted as guaranteed flow through every outlet or at 50 PSI. Actual flow will decrease as pressure, plumbing restriction and simultaneous water demand increase.

---

🚿 SUITABLE FOR UP TO THREE OUTLETS

The FLOJET is designed to accommodate up to three outlets in a correctly designed fresh water system.

A typical caravan setup might include:

• 🚰 Kitchen sink
• 🚿 Shower
• 🚰 Bathroom basin

Multiple outlets can share the same pump, but opening several at once divides the available flow between them.

If strong simultaneous flow from multiple outlets is critical, total fixture demand should be compared against the pump's available flow.

---

🔇 SOFT NOISE-ABSORBING MOUNTS

Fresh water pumps can transfer vibration directly into caravan floors and cabinetry, making them sound much louder than expected.

The FLOJET uses soft mounting points designed to reduce vibration transfer into the surrounding structure.

For best results, avoid rigid plumbing immediately against the pump and make sure the mounting surface is secure.

---

🛡️ SHORT-TERM DRY-RUN CAPABILITY

The pump can run dry for short periods without damage, providing useful protection if the fresh water tank runs empty or the pump briefly loses its water supply.

⚠️ Dry-run protection is intended as a safeguard. Do not intentionally leave the pump running without water for extended periods.

---

🌡️ THERMAL OVERLOAD PROTECTION

Built-in thermal overload protection helps safeguard the pump motor if excessive operating temperature occurs.

This is useful protection in mobile installations, but repeated thermal shutdown should be investigated rather than treated as normal operation.

---

🔥 ISO 8846 IGNITION PROTECTION

The pump meets ISO 8846 ignition-protection requirements.

This makes it suitable for compatible marine and mobile applications where ignition-protected electrical equipment is required.

⚠️ Ignition protection does not override other installation requirements. Wiring, fusing, mounting and plumbing must still comply with the requirements of the application.

---

⚡ ELECTRICAL PERFORMANCE

Power Supply: 12V DC

Current Draw at 10 PSI: Approximately 4.4A

Current Draw at 50 PSI: Approximately 7.5A

Approximate Electrical Input at 10 PSI: 53W @ 12V

Approximate Electrical Input at 50 PSI: 90W @ 12V

Current draw rises as the pump operates against increasing pressure because the motor has to work harder.

---

🔋 SUITABLE FOR LITHIUM & AGM AUXILIARY SYSTEMS

The pump can operate from a suitable 12V auxiliary battery system including compatible AGM and lithium installations.

With a listed current draw of approximately 4.4A at 10 PSI and 7.5A at 50 PSI, the pump represents a manageable load for most properly designed caravan electrical systems.

Because a fresh water pump usually operates only while water is being used, its total daily battery consumption is generally modest compared with continuous loads such as fridges.

---

❓ FREQUENTLY ASKED QUESTIONS

Is this a good pump for a caravan with a kitchen sink and shower?

Yes. With up to 11LPM flow and a 50 PSI pressure switch, it is much better suited to a complete caravan fresh water system than a small 3–4LPM single-outlet pump.

Can it run a kitchen tap, bathroom basin and shower?

The pump is designed to accommodate up to three outlets. If several are opened simultaneously, the available flow will be shared between them, so actual performance depends on the flow requirement of each fixture.

Will it give me decent shower pressure?

It has substantially more flow and pressure capability than a compact low-flow pump, making shower use a strong application. Final shower performance will still depend on the shower head, hose size, filters and other plumbing restrictions.

Can I run two outlets at once?

Yes, but the 11LPM maximum available flow is shared. For example, two lower-flow outlets may work comfortably together, while two high-flow fixtures can noticeably reduce pressure and flow at each outlet.

Will it automatically start when I open a tap?

Yes. It is an automatic pressure pump. Opening a tap lowers system pressure and starts the pump, while closing the tap allows pressure to build until the pump switches off.

Do I need a separate pressure switch?

No. The 50 PSI pressure-switch system is built into the pump.

Do I need an accumulator tank?

Not necessarily. The built-in bypass is designed to reduce pulsation and pump cycling, which can reduce the need for an accumulator tank. An accumulator may still provide benefits in some systems, but it is not automatically required.

What is the advantage of the built-in bypass?

It allows the pump to better handle lower water demand without constantly switching on and off. This can provide smoother water delivery when a tap is partially opened and can reduce noticeable pulsation through the plumbing.

Can I mount the pump above the water tank?

Yes, within its specified limits. The pump can self-prime up to approximately 2.5 metres, giving you considerable flexibility when choosing a mounting location.

Is 2.5 metres the maximum hose length?

No. It refers to the stated self-priming capability rather than total hose length. Longer plumbing can still be used where appropriate, but restrictions and air leaks can reduce performance.

Will it work if the fresh water tank runs empty?

The pump can run dry for short periods without damage, providing some protection if the tank empties. It should not be left operating dry unnecessarily.

Will it run from a 100Ah lithium battery?

Yes. A maximum listed operating current of approximately 7.5A is relatively modest for most suitable 100Ah lithium auxiliary batteries.

Can I run it from an AGM battery?

Yes. A healthy 12V AGM auxiliary battery can power the pump when it is correctly wired and protected.

How much battery does the pump actually use?

Even at 7.5A, ten minutes of continuous pump operation would use approximately 1.25Ah. In normal caravan use the pump usually runs intermittently, so daily battery consumption is generally relatively small.

Why does the pump draw more amps at higher pressure?

The motor has to work harder as pressure increases. The supplied figures show approximately 4.4A at 10 PSI and 7.5A at 50 PSI.

Will I actually get 11LPM from the shower?

Not necessarily. The 11LPM figure is the pump's maximum stated flow rating. Real-world shower flow will be lower where the pump is operating against pressure and plumbing restriction.

Is 50 PSI too much for caravan plumbing?

That depends on the components fitted. Before installing the pump, confirm that hoses, filters, taps, hot-water systems and fittings are compatible with the pump's pressure specification.

Can I install a water filter with this pump?

Yes, provided the filter is suitable for the system pressure and flow. Restrictive filters can reduce performance, so the filter should be sized appropriately.

Can I use this with a caravan hot-water system?

Potentially, provided the hot-water system's inlet pressure rating, flow requirements and plumbing specifications are compatible with the FLOJET pump. Check the water heater manufacturer's maximum permitted inlet pressure before installation.

How does this compare with a 3.8LPM pump?

The FLOJET is significantly better suited to showers and multi-outlet systems. A 3.8LPM pump is ideal for a small sink or single outlet, while this 11LPM model is designed for more demanding caravan and RV plumbing.

How does it compare with the SEAFLO 42 Series 11.3LPM pump?

Both are aimed at higher-flow caravan and RV water systems and include self-priming and bypass-style technology. The FLOJET is listed at 11LPM, uses a triplex diaphragm design, self-primes to 2.5 metres and incorporates a 50 PSI pressure switch. The better choice will depend on required pressure, plumbing connections, installation space and preferred pump design.

Will the pump be noisy inside a caravan?

The soft mounting system is designed to reduce transmitted vibration, but installation makes a major difference. Mounting the pump against a lightweight hollow panel or using rigid plumbing can amplify noise, so careful positioning is worthwhile.

Does it come with plumbing fittings?

Yes. Four plug-in hose port fittings are included. Exact connection sizes have not been provided here, so check the fitting dimensions against your existing caravan plumbing before installation.

Is it suitable for a boat?

It may suit compatible marine fresh water systems, and the pump meets ISO 8846 ignition-protection requirements. The complete marine installation still needs to comply with the relevant electrical and plumbing requirements.

Would this be a good replacement for an older caravan water pump?

Potentially. Compare your existing pump's voltage, flow, pressure, port size, mounting arrangement and electrical requirements. Also check that the existing plumbing can safely handle the FLOJET's 50 PSI pressure-switch specification.

What should I check before buying?

Confirm that 11LPM is appropriate for the number of outlets in your system, check that all plumbing components can handle the pump's pressure, verify the supplied port fitting sizes, make sure your installation is within the 2.5 metre self-priming limit and confirm the required fuse and cable sizing before wiring it in.
