70W High-Pressure Diaphragm Self-Priming Water Pump

Power through every wash, irrigation, or fluid-transfer task with this 70W DC12V Diaphragm Self-Priming Pump. Delivering up to 130 PSI (0.90 MPa) and a maximum flow rate of 6 litres per minute, this compact, heavy-duty pump is built for reliable performance across a wide range of applications — from car and vehicle washing to lawn irrigation, carpet cleaning, and water treatment equipment.

Key Features

Auto On/Off Pressure Switch: The intelligent pressure valve automatically cuts power when the outlet is closed and restores it the moment flow is needed — protecting the motor and saving energy.
High-Pressure Performance: Max pressure of 130 PSI (0.90 MPa) with a pump head of up to 70 m for excellent reach and spray force.
Self-Priming Design: Primes itself from up to 1–2 m depth — no manual priming required.
Corrosion-Resistant Materials: Constructed with imported corrosion-resistant components for long-term durability with water and mild chemical solutions (pH 5–8).
Thermal Protection: Built-in thermal overload protection prevents motor burnout during extended use.
Vibration-Dampening Rubber Bracket: Minimises noise and vibration during operation for smoother, quieter performance.
Continuous Load Capable: Engineered for long-duration continuous and intermittent operation without overheating.
Compact & Portable: Handheld-friendly size of 16.5 × 10 × 6 cm — easy to install in tight spaces.

Frequently Asked Questions

Q: What power source does this 70W diaphragm water pump require?

A: This pump runs on DC 12V (compatible with 10–20V DC sources), drawing 6A of current. It is ideal for use with a 12V car battery, portable power station, or dedicated DC power supply — making it perfect for mobile vehicle washing and off-grid irrigation setups.

Q: Does this self-priming water pump turn off automatically?

A: Yes. The built-in intelligent pressure switch automatically cuts power to the motor when the outlet valve is closed and restarts it when flow is needed again. This protects the motor, saves power, and makes operation hands-free once connected.

Q: Can I use this pump for garden spraying and lawn irrigation?

A: Absolutely. With a flow rate of up to 6 L/min and a maximum pressure of 130 PSI, this pump is well-suited for lawn and garden irrigation, fertiliser spraying (pH 5–8), and general outdoor water distribution tasks.

Q: Is this pump submersible?

A: No. This is not a submersible pump. It must be installed in a dry, well-ventilated location above the water source. It can self-prime from a water source up to 1–2 metres below the pump inlet.
