24 volt High Pressure 11 bar Diaphragm Pump 5,5L/m

Powerful Water Pressure for Cleaning, Spraying & Misting

Need strong water pressure from a compact, portable pump? The 24 Volt High Pressure 11 Bar Diaphragm Pump is designed for applications that require powerful water pressure and controlled water flow without relying on mains electricity.

With a maximum pressure of 11 bar (160 PSI) and a maximum flow rate of 5.5 litres per minute (330 L/h), this 24V DC diaphragm pump is ideal for portable car washing, carpet cleaning, agricultural spraying, patio misting and general mobile water transfer.

Its self-priming design allows it to draw water from a source up to 1.5 metres below the pump, while the built-in automatic pressure switch helps control operation according to system pressure.

Featuring a three-diaphragm design, stainless steel shaft and Viton seals, the pump is built for demanding high-pressure applications. Rubber mounting feet also help reduce vibration and noise during operation.

Whether you're setting up a portable cleaning system or supplying water to compatible spraying equipment, this compact pump delivers the pressure needed for a variety of intermittent-use applications.

Why You'll Love It

  • High-Pressure Performance: Delivers up to 11 bar (160 PSI) for demanding cleaning and spraying applications.

  • Maximum Flow Rate of 5.5 L/min: Moves up to 330 litres of water per hour under ideal conditions.

  • 24V DC Operation: Ideal for compatible low-voltage and mobile pumping systems.

  • Automatic Pressure Switch: Starts and stops the pump in response to system pressure.

  • Self-Priming Up to 1.5 Metres: Draws water from a suitable source below the pump.

  • Three-Diaphragm Design: Designed to provide reliable high-pressure pumping performance.

  • Dry-Run Capability: Can tolerate running dry without immediate damage under suitable conditions.

  • Viton Seals: Suitable for certain compatible liquids within the specified pH range.

  • Stainless Steel Shaft: Provides durability for demanding pumping applications.

  • Rubber Mounting Feet: Help reduce vibration and operating noise.

  • Compact & Portable: Convenient for mobile cleaning and spraying equipment.

  • 10 mm Hose Connection: Features a 3/8" hose barb connection for compatible tubing.

Ideal for High-Pressure Applications

The 24V 11 Bar Diaphragm Pump is a practical choice for applications where strong pressure and relatively low water volumes are required.

It's particularly useful for:

  • Portable Car Washing: Supply pressurised water to compatible mobile car wash equipment.

  • Carpet Cleaning Machines: Provide water pressure for suitable carpet and upholstery cleaning systems.

  • Agricultural Spraying: Support compatible crop spraying and garden spraying equipment.

  • Patio Misting Systems: Supply pressurised water to suitable misting nozzles.

  • Mobile Cleaning Equipment: Ideal for portable cleaning and washing applications.

  • Sweepers & Cleaning Machines: Supply water to compatible cleaning equipment.

  • General Water Transfer: Move water in applications requiring higher discharge pressure.

Automatic Pressure Control

The pump features a built-in automatic pressure switch that helps manage water delivery during operation.

When system pressure drops, the pump starts automatically to supply water. Once the system reaches the switch's shut-off pressure, the pump stops.

This makes it convenient for cleaning and spraying systems where water is used intermittently.

Important: All hoses, fittings and valves must be properly sealed. Leaks can cause repeated start-and-stop cycling, placing unnecessary strain on the motor and pressure switch.

Compact Design, Powerful Performance

The pump's three-diaphragm construction is designed to provide the pressure needed for demanding spraying and cleaning applications.

Its stainless steel shaft and Viton seals provide durability, while the rubber mounting feet help reduce vibration during operation.

The compact design also makes it suitable for portable equipment and installations where space is limited.

For best performance, mount the pump vertically as specified and use suitable flexible high-pressure hose.

Because this pump can generate up to 11 bar, all hoses, clamps, fittings and connected equipment must be rated for the required operating pressure.

Important Operating Information

This pump is designed for intermittent operation only and must not run continuously.

To help protect the motor and automatic pressure switch:

  • Maximum Running Time: Operate for no longer than 30 minutes at a time.

  • Cooling Period: Allow at least 20 minutes OFF between operating cycles and ensure the motor has cooled to ambient temperature before restarting.

  • Avoid Frequent Cycling: Repeated starting and stopping can damage the automatic pressure switch.

  • Check for Leaks: Poor hose connections, leaking fittings and valves that do not close properly can cause unnecessary pump cycling.

  • Maintain Correct Voltage: Use a suitable regulated 24V DC power supply capable of supplying the required current.

  • Prevent Low Voltage: Insufficient voltage may prevent the pump from reaching its shut-off pressure, leading to overheating and motor damage.

  • Secure All Hoses: Use suitable hose clamps to prevent connections from loosening under pressure.

  • Use High-Pressure Hose: Ensure all hoses and fittings are rated for the pump's maximum pressure.

  • Avoid Kinked Pipes: Keep hoses free from bends and restrictions that could affect water flow.

  • Dry-Run Capability: Although the pump can tolerate dry running, avoid unnecessary extended operation without liquid.

  • Chemical Compatibility: Confirm that any liquid being pumped is compatible with the Viton seals and all other internal components.

  • No Flammable Liquids: Never use this pump to transfer petrol, diesel, solvents or other flammable liquids.

  • Correct Installation: Mount the pump vertically and follow the manufacturer's installation instructions.

With its 11 bar maximum pressure, automatic pressure switch and compact 24V design, this diaphragm pump is a practical choice for portable car washing, agricultural spraying, patio misting and other intermittent high-pressure applications.
