Rule iL280P Plus Centrifugal Submersible & Inline Water Pump

The Rule iL280P / iL280P-24 is a portable centrifugal pump for submerged or flooded-inlet inline use, rated at 280 GPH (1,080 LPH; approx. 18 litres/minute). This pump-only listing includes the pump and removable inlet strainer.

The Rule iL280P / iL280P-24 Slimline pump is designed for portable water transfer and washdown tasks on boats, vehicles and around the home. The pump can be submerged directly into liquid with its inlet strainer fitted, or installed inline after removing the strainer and ensuring the inlet remains flooded. It is a centrifugal pump and is not self-priming.

What Is the Rule iL280P / iL280P-24 Water Pump Used For?

Typical uses include deck washdown, deck showers, sink draining, container filling and emptying, engine winterising, anchor washing and general fresh-water or seawater transfer. The pump can also handle compatible antifreeze and diesel, but every hose, connector and electrical component in the system must be suitable for the liquid being transferred.

What Is Included?

• One Rule Slimline centrifugal pump
• Removable inlet strainer

What Is Not Included?

• Permanent vessel wiring, switch and circuit protection
• Through-hull fittings and fixed plumbing
• Transfer hose, battery clips and spray nozzle

Which Water-Transfer Applications Is This Pump Suitable For?

• Choose the version that matches the available supply: 12V / 24V.
• Use submerged with the inlet strainer fitted, or inline with a flooded inlet.
• Not self-priming: do not install above the liquid source and expect it to lift water through a dry suction line.
• Do not run dry for extended periods.

Can This Pump Be Used Submerged and Inline?

Yes, where the selected model is installed within its published operating modes: Submersible with strainer or inline with strainer removed. The pump is listed as self-priming: No - flooded inlet required for inline use; an inline installation therefore requires the inlet to remain flooded.

How Do I Select the Correct Variant?

Select the pump from the complete hydraulic and electrical requirement:

• Supply voltage: 12V DC / 24V DC
• Rated flow: 280 GPH (1,080 LPH; approx. 18 litres/minute)
• Maximum head: 9.7 m (32 ft)
• Maximum pressure: 14 psi (0.96 bar)
• Outlet connection: 13 mm (1/2 in) hose connection
• Duty rating: Continuous duty; do not run dry for extended periods

Construction and Design

• Pump body material: Acetal pump body
• Duty rating: Continuous duty; do not run dry for extended periods
• Self-priming: No - flooded inlet required for inline use
• Operating modes: Submersible with strainer or inline with strainer removed
• Dimensions: 165 x 38 mm (L x diameter)

Installation and Safety

For submersible use, fully immerse the inlet and keep the strainer clear. For inline use, remove the strainer, connect the specified hose size and position the pump below the source liquid level so the inlet remains flooded. Use the correct voltage, protect the circuit with an appropriate fuse, observe liquid compatibility, and never use temporary battery connections where they could short or become wet.

Maintenance

Inspect the pump, hoses and electrical connections regularly, particularly after salt-water use or portable operation.

• Flush with clean water where practical after transferring salt water.
• Clear the inlet strainer and investigate any reduction in flow.
• Inspect hoses, clips, cables and connectors for damage or leakage.
• Do not continue operating a pump that is noisy, seized, leaking or overheating.

Key Features

• Rated flow: 280 GPH (1,080 LPH; approx. 18 litres/minute)
• Dual-use centrifugal design for submersible or inline operation
• Removable inlet strainer
• Suitable for fresh water, seawater, compatible antifreeze and diesel with suitable plumbing
• Compact body for portable marine and general-purpose use
• Continuous-duty rated on Plus models; avoid extended dry running

Frequently Asked Questions

Is this pump self-priming?
No. In inline use the inlet must be flooded before the pump is switched on.

Can it pump seawater?
Yes. The Slimline range is specified for fresh water and seawater. Rinse with fresh water after salt-water use where practical.

Can it transfer diesel?
The pump can handle diesel, but the entire hose and connection system must be fuel-compatible. Some kits include water hose that is not suitable for diesel.

Can it run dry?
Do not allow extended dry running. The basic iL200 is not continuously rated; Plus models are continuously rated but still require liquid for normal cooling and pumping.
