High Pressure 11 bar 12 volt Diaphragm Pump 5,5L/h

Powerful High-Pressure Water Pump for Cleaning, Spraying & Misting

Need strong water pressure from a compact 12V pump? The High 11 Bar Pressure 12V Diaphragm Pump is designed for applications that need powerful water pressure without relying on a standard mains-powered pump.

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

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.

The pump features a three-diaphragm design, durable stainless steel shaft and rubber mounting feet to help reduce vibration and noise during use.

Compact and portable, it's a practical solution for cleaning and spraying equipment where high pressure and a 12V DC power supply are required.

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.

  • 12V DC Operation: Ideal for compatible portable and mobile pumping systems.

  • Automatic Pressure Switch: Controls pump operation in response to system pressure.

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

  • Dry-Run Capability: Designed to tolerate running dry without immediate motor damage.

  • Three-Diaphragm Design: Provides efficient pumping performance for high-pressure applications.

  • Viton Seals: Suitable for compatible liquids within the specified pH range of 4–11.

  • Stainless Steel Shaft: Designed for durability in demanding applications.

  • Rubber Mounting Feet: Help reduce noise and vibration during operation.

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

  • Hose Barb Connection: Features a 3/8" (10 mm) connection for compatible tubing.

Ideal for High-Pressure Cleaning & Spraying

The 11 Bar 12V Diaphragm Pump is a versatile option for applications that require strong water pressure from a compact pumping system.

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 cleaning systems.

  • Agricultural Spraying: Support compatible crop 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 equipment.

  • General Water Transfer: Move water where higher discharge pressure is required.

Automatic Pressure Control

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

When the system pressure drops, the pump starts to supply water. Once the required shut-off pressure is reached, the pump stops automatically.

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

Important: All connections must be properly sealed. Leaking fittings, taps or valves can cause repeated start-and-stop cycling, which may damage the pressure switch and motor.

Designed for Portable High-Pressure Applications

The pump's compact construction makes it suitable for installation in mobile cleaning equipment and other applications where space is limited.

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

For best performance, install the pump in a vertical position 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 use only and must not run continuously.

To protect the motor and pressure switch, follow these guidelines:

  • 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.

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

  • Check for Leaks: Poor hose connections, leaking fittings and taps that do not close properly can cause the pump to cycle repeatedly.

  • Maintain Correct Voltage: Use a suitable 12V DC power supply capable of delivering the required current. Low voltage may prevent the pump from reaching its shut-off pressure and can lead to motor damage.

  • Secure All Hoses: Use pressure-rated hose clamps and fittings to prevent connections from coming loose under pressure.

  • Use High-Pressure Hose: Ensure the hose and all connected components are suitable for the pump's maximum pressure.

  • Dry-Run Capability: Although the pump can tolerate dry running, avoid unnecessary extended dry operation.

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

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

With its 11 bar maximum pressure, automatic pressure switch and compact 12V design, this diaphragm pump is a practical choice for portable cleaning, agricultural spraying and other high-pressure water applications.
