---

🔄 TWO OPERATING CONFIGURATIONS

💧 Fully Submersible

With the clip-on strainer installed, the Congo can be lowered directly into a suitable water or diesel source.

This arrangement is particularly convenient for drums, tanks and portable containers where fitting a permanent suction line is unnecessary.

🔧 In-Line

Remove the strainer and the pump reveals a connection suitable for 20mm / 3/4" hose.

The in-line configuration is useful where the pump can be installed in a flooded or gravity-fed line between the source and destination.

---

⚠️ NOT SELF-PRIMING

The Rule IL500P is a centrifugal pump and is specifically listed as not self-priming.

For correct operation, the pump must either:

• 💧 Be fully submerged in the liquid, or
• ⬇️ Receive liquid through a gravity-fed inlet, or
• 🔄 Be used with an appropriate one-way valve arrangement that maintains liquid at the pump inlet

⚠️ IMPORTANT: Do not mount the pump above a tank and expect it to draw liquid through an empty suction hose. The inlet must already be flooded or primed.

---

⏱️ CONTINUOUS-DUTY MOTOR

The Congo uses a continuously rated motor, making it better suited to larger transfer jobs than an intermittent-duty pump.

This is particularly useful when filling larger tanks or transferring significant quantities of water or diesel.

⚠️ DRY-RUN WARNING: Continuous-duty motor rating does not mean the pump should be operated dry. The pump is specifically stated not to be run dry for long periods.

---

⛽ DIESEL TRANSFER READY

The IL500P is specifically listed for diesel transfer, giving it additional versatility beyond fresh water pumping.

Its combination of high 32LPM flow, slim body, long electrical lead and alligator battery clips makes it useful for portable diesel transfer and suitable refuelling applications.

Potential uses include:

• ⛽ Transferring diesel from drums
• 🚜 Refuelling compatible diesel machinery
• 🚚 Diesel vehicle refuelling
• 🚤 Marine diesel transfer
• 🌾 Agricultural fuel transfer

⚠️ NOT FOR PETROL: The Rule IL500P is listed for diesel transfer, not petrol. Do not use it with petrol or assume compatibility with other volatile fuels.

---

📏 UP TO 9 METRE HEAD

The Congo is listed with a maximum head of approximately 9 metres.

Head represents the maximum vertical column of liquid the pump can work against under the stated conditions.

As vertical lift and plumbing resistance increase, available flow decreases.

---

🚐 FAST CARAVAN & CAMPING WATER TRANSFER

The Congo is particularly useful for travellers who carry fresh water in portable containers and want to transfer it quickly into a larger fixed tank.

Rather than lifting a heavy water container and pouring it manually, the pump can be lowered directly into a suitable drum and connected to a hose leading to the caravan or vehicle tank.

With a stated capacity of up to 32LPM, the Congo can make larger transfer jobs significantly faster.

❓ FREQUENTLY ASKED QUESTIONS

How does the IL500P Congo compare with the IL280P Amazon?

The Congo is the higher-flow option. It is rated at up to 32LPM compared with 18LPM for the Amazon. Both are continuously rated, can transfer water or diesel and operate either submerged or in-line, but the Congo uses a larger 20mm / 3/4" hose connection for higher-volume transfer.

Is the Congo worth choosing over a smaller transfer pump?

Yes if transfer speed is important. If you're regularly filling large caravan tanks, transferring diesel or moving substantial volumes of water, the 32LPM capacity can save considerable time. For occasional small-container transfer, a lower-flow model may be adequate.

How quickly could it theoretically empty a 20L container?

At the stated maximum flow of 32LPM, 20 litres would theoretically take around 38 seconds. Actual transfer will take longer because hose length, lift, fittings and restrictions reduce real-world flow.

Can I drop it straight into a 20L water drum?

Yes, provided the opening is large enough for the approximately 41mm diameter pump body. The slimline design is specifically intended to fit into many 20-litre drum openings.

Can I use it to fill my caravan water tank from jerry cans?

Yes. This is one of its most practical touring applications. Place the pump into a suitable water container, connect 20mm hose to the destination tank and power it from an appropriate 12V battery.

Is 32LPM too much for filling a caravan tank?

That depends on the tank filler and breather arrangement. A high-flow pump can transfer water quickly, but the receiving tank and filler plumbing must be able to accept the flow without backing up or overflowing. You can also restrict flow where necessary.

Can I use it as my normal caravan tap pump?

Generally no. The IL500P is a high-volume centrifugal transfer pump and no automatic demand pressure switch is specified. A self-priming diaphragm pressure pump is normally more appropriate for a caravan sink or shower system that needs automatic operation when a tap opens.

Does it automatically turn on when I open a tap?

No automatic pressure-switch function is specified. The pump requires a suitable electrical switching arrangement.

Is it self-priming?

No. It must be fully submerged or receive liquid through a flooded or gravity-fed inlet.

Can I mount it above the tank?

Not if it would need to pull liquid through an empty suction line. Because the pump is not self-priming, the inlet must already be flooded.

Will a one-way valve help?

In some in-line installations, a one-way valve can help retain liquid in the inlet line and maintain prime when the pump stops. The plumbing arrangement still needs to provide reliable liquid supply to the pump.

Can I leave it running continuously?

The motor is continuously rated, so it is intended for longer operating periods. However, the pump should remain supplied with liquid and should not be run dry for extended periods.

Can it run dry?

Not for prolonged periods. Continuous motor duty and dry-run capability are different specifications. The Congo should normally remain flooded while operating.

Can I transfer diesel with it?

Yes. Water and diesel transfer are both explicitly listed applications for the IL500P.

Can I drop it directly into a diesel drum?

The pump is listed for diesel transfer and its slim body is designed for drum applications. Confirm that the actual filler opening will accommodate the approximately 41mm pump body and use diesel-compatible transfer hose.

Can I use it to refuel a diesel 4WD, truck or tractor?

Diesel refuelling and transfer are listed applications for the pump range. Use appropriate diesel-rated hose, containers and safe fuel-handling procedures.

Can I use it for petrol?

No. The pump is specifically described for diesel transfer and not petrol.

Can I use it for AdBlue?

Do not assume compatibility. Chemical compatibility with AdBlue has not been specifically provided. Confirm suitability with the pump manufacturer before use.

Can it pump chemicals?

The broader Rule range is described as capable of pumping various chemicals, but compatibility depends on the exact liquid. Check the chemical against the pump's materials before use rather than assuming universal compatibility.

Can it pump salt water?

Salt-water deck wash and shower applications are included among the stated uses of the broader pump range. If regular salt-water operation is intended, confirm the IL500P's maintenance and flushing requirements for that application.

Can I use it as an emergency bilge pump?

The Rule range lists emergency bilge pumping as an application. If the IL500P will be relied upon as safety equipment, confirm its exact approval, installation method and required capacity for the vessel rather than treating a portable transfer pump as an automatic bilge system.

Can I use it for a portable camping shower?

Potentially, but 32LPM is substantially more flow than most shower heads require. A smaller pressure pump may provide better control for a conventional shower system. The Congo is primarily attractive where rapid transfer is required.

Will it deliver 32LPM at a 9 metre vertical lift?

No. The 32LPM maximum flow and 9 metre maximum head occur under different operating conditions. Flow decreases as vertical lift and pressure increase.

Can I use a long 20mm hose?

Yes, but longer hose adds resistance and reduces flow. Keeping the hose diameter at 20mm / 3/4" and minimising unnecessary bends will help preserve performance.

Does it come ready to clip onto a battery?

Yes. The pump includes approximately 4 metres of wiring cable with alligator clips for connection to a suitable 12V battery.

Can I run it from a lithium battery?

Yes, provided the battery supplies a suitable 12V output and the pump's actual current requirement is within the battery and wiring capability.

Can I permanently wire the Congo into my vehicle or caravan?

Potentially, but confirm the pump's actual current draw and required fuse protection before altering the supplied lead. Permanent wiring should use correctly rated cable, switching and circuit protection.

What should I check before buying?

Confirm that you need high-volume transfer rather than an automatic pressure pump, check that 20mm / 3/4" hose suits your application, measure any drum opening against the pump's 41mm body diameter, make sure the pump can remain submerged or gravity fed and confirm compatibility if you intend to pump anything other than water or diesel.
