Adjustable membrane water pump 6-12V 1-2 L/min R385 pump - 3 m head

Adjustable membrane water pump 6-12V 1-2 L/min R385 pump - 3 m head

This 6V - 12V water pump is a versatile, efficient device, ideal for a wide range of applications, including DIY projects with Arduino, ESP32, ESP8266, and Raspberry Pi. Thanks to its diaphragm design, the pump can draw liquid without needing to be submerged, which makes it extremely practical and easy to use. Flow regulation by changing the supply voltage allows precise adjustment to your circuit’s needs.

Key technical specifications

• Rated voltage: DC 6V - 12V
• Rated current: 0.6A - 2A
• Type: Diaphragm (creates vacuum to draw liquid without submerging)
• Liquid flow regulation: By changing supply voltage
• Water head (lift): Up to 300 cm maximum
• Flow rate: 1 - 2 L/min
• Inlet diameter: 7.5 mm
• Outlet diameter: 7.5 mm

Benefits

• Greater versatility: Diaphragm construction allows drawing liquid without direct submersion of the pump.
• Full control: Adjustable flow via supply voltage lets you match parameters to specific requirements.
• High performance: Can lift liquid up to 300 cm with flow around 1 - 2 L/min.
• Compact design: Small size and standard 7.5 mm inlet/outlet diameters simplify integration with various systems.
• Economical operation: Energy efficiency and low current draw keep running costs low.

Example applications

• Automatic plant irrigation systems
• Educational DIY and robotics projects (Arduino, Raspberry Pi)
• Aquarium aeration and filtration systems
• Small fountains and decorative ponds
• Household devices that need precise water transfer

This 6V - 12V water pump is a reliable choice for systems that need efficient, flexible liquid pumping. Its diaphragm design and smooth flow adjustment make it suitable for both home use and more advanced electronic projects.
