Product Information

Full details

The Hardi 18824V electric diaphragm fuel pump is a robust, high-performance solution designed primarily for demanding marine applications requiring 24V power. It excels by providing consistent fuel delivery independent of engine speed, making it an ideal choice for high-horsepower engines. While it offers exceptional versatility and maintenance-free operation, users should ensure the pump's specific pressure and flow output align with the requirements of their particular fuel delivery system to avoid performance mismatches.

FAQs

Can I use this pump with biodiesel?

Yes, the Hardi 18824V is compatible with various fuels including petrol, diesel, and alcohol blends.

Does this pump need a return line?

The pump is designed to regulate flow based on demand, but always consult your engine manual regarding your specific fuel system architecture.

Is it safe to mount the pump in the engine room?

Yes, it is rated for temperatures up to 80C and is interference-suppressed, making it suitable for engine room installation.

What is the maximum engine horsepower this pump can support?

The unit is designed for engines rated at 100 HP and higher.

What should I do if the pump makes a loud noise?

A clicking sound is normal during operation as the diaphragm moves. If the sound is abnormal, check for loose mounting hardware.

Does the pump include an internal filter?

It is highly recommended to install a separate pre-filter in the fuel line before the pump to protect the internal diaphragm from debris.

Troubleshooting

Pump is failing to draw fuel during startup.

Check for air leaks in the intake side of the fuel line and ensure the pump is mounted within the recommended distance from the fuel tank.

Unit clicks excessively without pumping fuel.

This often indicates a blockage in the filter or fuel line; inspect and clean the fuel filters and verify that the tank vent is not obstructed.

Unstable engine performance at high RPM.

Verify that the voltage at the pump terminals is a steady 24V. Low voltage can limit the stroke frequency and reduce flow rates.

Pros and Cons

Pros

  • Independent of engine speed for consistent flow
  • Suitable for engines over 100 HP
  • Self-priming functionality
  • Maintenance-free diaphragm operation
  • Wide operating temperature range (-40C to +80C)

Cons

  • Requires 24V electrical source
  • Specific pressure range may not suit all low-pressure carburetors
  • Fixed 8mm pipe connections limit fitting options

Setup, Compatibility & Care

Ensure the installation area is protected from direct water spray, though the unit is designed for the harsh conditions of marine engine compartments.

  1. Connections: The pump features 8mm pivoted connectors; ensure your fuel lines are compatible with these dimensions and secured with appropriate hose clamps.
  2. Electrical: Connect to a stable 24V power source. Use a fused circuit to protect the pump from electrical surges.
  3. Mounting: While versatile, vertical mounting near the fuel tank is generally recommended to assist the self-priming process.
  4. Maintenance: Because the unit is maintenance-free, periodic inspection should focus solely on the exterior, checking for tight hose connections and ensuring the wiring remains free from corrosion.
