12V 45W Self-Priming Diaphragm Booster Pump Auto Start/Stop
12V 45W Self-Priming Diaphragm Booster Pump Auto Start/Stop
12V 45W Self-Priming Diaphragm Booster Pump with Automatic Start/Stop
Deliver reliable, consistent water pressure wherever you need it with this compact 12V 45W Self-Priming Diaphragm Booster Pump. Engineered for versatility, its automatic start/stop pressure switch activates the pump on demand and shuts it off when flow stops — saving energy and extending pump life without any manual intervention.
Whether you're boosting water pressure in a commercial building, setting up a drip irrigation system, washing down equipment, or watering plants and fruit trees, this low-pressure diaphragm pump handles the job quietly and efficiently.
Made in Mainland China.
Key Features
- Automatic Start/Stop: Built-in pressure switch starts the pump when flow is detected and stops it automatically when the line closes — no manual switching required.
- Self-Priming Design: Pulls water from the source without pre-filling, making setup fast and straightforward.
- Diaphragm Sealing: Durable diaphragm construction handles clean water and alcohol-based fluids with no contamination risk.
- Compact & Lightweight: At just 650 g, this pump installs easily in tight spaces — under sinks, in caravans, RVs, boats, or field equipment.
- Low Voltage Operation: Runs on 12V DC, compatible with solar panels, batteries, and standard DC power supplies.
- 1/2" (4 min) External Thread Outlet: Standard fitting for easy integration with most hose and pipe systems.

Frequently Asked Questions
Q: What type of liquids can this 12V diaphragm booster pump handle?
A: This self-priming diaphragm pump is compatible with clean water, hot water, and alcohol-based fluids. It is not designed for abrasive slurries, corrosive chemicals, or liquids outside those specified. Always verify fluid compatibility before use.
Q: How does the automatic start/stop function work on this booster pump?
A: The pump features a built-in pressure switch that detects when a tap or valve is opened (drop in line pressure) and automatically starts the pump. When the flow is stopped, the pressure builds back up and the switch cuts power to the motor — no manual switching needed and no wasted electricity.
Q: Is this pump suitable for solar or battery-powered off-grid setups?
A: Yes. Operating at 12V DC with a maximum draw of 45W, this diaphragm booster pump is an excellent choice for off-grid systems powered by 12V solar panels or deep-cycle batteries, including RVs, boats, caravans, and remote agricultural installations.
Q: What is the maximum pressure and flow rate of this pump?
A: The pump delivers a maximum pressure of 0.7 MPa and a maximum flow rate of 4 litres per minute, making it well-suited for low-pressure boosting tasks such as garden irrigation, cleaning, and light commercial water distribution.
