HIGH PRESSURE 7 BAR 24 VOLT WATER DIAPHRAGM PUMP 5L/M

High Pressure 7 bar 24 Volt Water Diaphragm Pump 5L/m

Compact High-Pressure Pump for Cleaning, Spraying & Misting

Need strong water pressure without a large, bulky pump? The High Pressure 7 Bar 24 Volt Water Diaphragm Pump is a compact and practical solution for applications that require high pressure and controlled water flow.

With a maximum pressure of 7 bar (100 PSI) and a maximum flow rate of 5 litres per minute (300 L/h), this 24V DC diaphragm pump is ideal for portable cleaning equipment, agricultural spraying, patio misting and general water transfer.

Its self-priming design allows it to draw water from a source up to 1 metre below the pump, while the built-in automatic pressure switch helps control operation as system pressure changes.

Designed with three diaphragms, a stainless steel shaft and rubber mounting feet, the pump combines high-pressure performance with a compact, portable design.

Whether you're setting up a portable car wash, maintaining a garden spraying system or supplying water to compatible misting nozzles, this pump offers a convenient solution for applications where high pressure and lower water volumes are required.

Why You'll Love It

• Maximum Flow Rate of 5 L/min: Moves up to 300 litres of water per hour under ideal conditions.

• 24V DC Operation: Suitable for compatible low-voltage pumping systems.

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

• Self-Priming Up to 1 Metre: Can draw water from a suitable source below the pump.

• Three-Diaphragm Design: Designed for 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 noise and vibration during operation.

• Compact & Portable: Easy to incorporate into 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 7 Bar Diaphragm Pump is designed for applications where you need strong pressure without moving large volumes of water.

It's a practical choice for:

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

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

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

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

• Engine Washing: Provide pressurised water for compatible cleaning equipment.

• Industrial Cleaning: Support smaller cleaning systems requiring high pressure.

• Water Filtration: Transfer water through compatible pressure-rated filtration systems.

• Fresh Water Transfer: Move water in suitable low-volume, high-pressure applications.

• Seawater & Chemical Transfer: Suitable only where the liquid is confirmed compatible with all pump materials and seals.

Automatic Pressure Control

This pump features a built-in automatic pressure switch that helps manage water delivery.

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

This is particularly useful for cleaning and spraying systems where water is used intermittently.

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

Built for Compact, High-Pressure Performance

The pump's three-diaphragm design helps deliver the pressure needed for 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 construction also makes it suitable for portable equipment and installations where space is limited.

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

Because the pump can generate up to 7 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 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 sufficiently 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 delivering the required current.

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

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

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

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

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

• Chemical Compatibility: Confirm that any chemicals or seawater are compatible with the pump's seals and 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 7 bar maximum pressure, automatic pressure switch and compact 24V design, this diaphragm pump is a practical choice for portable cleaning, agricultural spraying, patio misting and other intermittent high-pressure applications.
