R365 12V DC Diaphragm Based Water Pump

R365 12V DC Diaphragm Based Water Pump offers a reliable and compact solution for fluid handling in small-scale projects and appliances. This micro pump utilizes a diaphragm mechanism, which makes it self-priming and highly effective at transferring non-corrosive liquids, including water. Operating directly from a standard 12V DC source, this pump is easy to integrate into battery-powered systems or portable devices. Its design ensures a smooth, quiet operation while delivering a steady flow rate and moderate head pressure, making it an excellent component for DIY liquid dispensing, cooling systems, and experimental fluid dynamics. You can achieve controlled and consistent liquid movement using this dependable diaphragm pump.

Key Features:

• Self-Priming Capability: The diaphragm design allows the pump to draw fluid from below its mounting level without requiring an initial manual prime.
• Compact 12V DC Operation: Requires a common 12V supply, ensuring compatibility with most embedded systems and automotive power sources.
• Versatile Fluid Transfer: Capable of handling various non-corrosive liquids, including water, ethanol, and mild cleaning solutions.
• Low Noise and Vibration: Engineered for relatively quiet operation, making it suitable for applications where noise is a concern.
• Easy Integration: Features simple two-wire connection and compact mounting holes for quick setup in projects.

Pinout and Wiring:

• Red Wire (Positive): Connect this wire to the 12V power supply’s positive (+) terminal.
• Black Wire (Negative): Connect this wire to the power supply’s negative (-) or ground terminal.
• Note on Polarity: Observe the correct polarity for proper rotation and function. Reversing the polarity will not typically reverse the flow but may damage the motor or diaphragm over time.

Commonly Used in:

• Aquariums and Terrariums: Automating small water changes or maintaining filtration circulation.
• DIY Beverage Dispensers: Providing measured fluid delivery for custom machines.
• Computer/Microchip Cooling: Circulating coolant in low-flow liquid cooling loops.

Applications:

• Automatic Plant Watering Systems: Pumping water from a reservoir to irrigate plants on a schedule.
• Medical Equipment: Used in small sampling or dispensing instruments.
• Robotics and Science Projects: Moving liquids as part of experimental or mobile systems.

Equivalent Models:

• Submersible Pumps (Mini): Offers higher flow but lacks the R365’s self-priming capability.
• Peristaltic Pumps: Provides extremely precise, pulse-free flow at the expense of complexity and cost.
• 6V/24V R365 Variants: Alternative voltage versions for different power system needs.

Package Includes:

• 1 x R365 12V DC Diaphragm Based Water Pump
