70W 130PSI High-Pressure Diaphragm Water Pump – 6L/Min Self-Priming with Automatic Switch
70W 130PSI High-Pressure Diaphragm Water Pump – 6L/Min Self-Priming with Automatic Switch
The [70W] 130PSI High Pressure Diaphragm Water Pump is a compact, reliable, and efficient self-priming pump designed for high-demand water transfer, spray systems, and pressure-boosting applications. Capable of delivering up to 6 liters per minute (L/min) at a maximum pressure of 130 PSI, this pump is ideal for a wide variety of residential, automotive, marine, agricultural, and DIY uses.
Built with a durable diaphragm mechanism, the pump handles water and light liquids with ease, while the automatic pressure switch allows the unit to start and stop automatically based on the water flow demand. When the output valve is opened, the pump runs; when closed, it shuts off — preventing damage and conserving power.
Its self-priming capability ensures quick startup and enables the pump to draw water from low levels, even when dry for short periods. The sealed motor and corrosion-resistant materials make it suitable for long-term use in outdoor or damp environments.
