DC12V R27 small mini water pump with 370 motor — diaphragm, selfpriming, waterproof rubber cover A compact, reliable 12V DC diaphragm water pump built for portable and smallscale fluid handling. The R27 model uses a 370series motor and a selfpriming diaphragm design to deliver consistent water transfer and circulation with minimal setup. The included waterproof rubber cover improves durability in wet or exposed environments. Key benefits Portable 12V operation: Runs from any 12V DC source (battery, vehicle, 12V adapter, small solar systems), making it convenient for mobile and offgrid use. Selfpriming diaphragm design: Automatically primes without manual filling, simplifying installation and reducing downtime. Compact but effective: Small footprint fits into tight spaces for hobby, automotive, or home projects where larger pumps won't work. Protected in wet conditions: Waterproof rubber cover adds protection to the motor assembly for increased reliability in damp environments. Main features and attributes Model: R27 Motor type: 370 motor (DC) Voltage: DC 12V Pump type: Diaphragm selfpriming water pump Protection: Waterproof rubber cover included Application fluid: Water (designed for water transfer and circulation) Installation: Simple wiring to a 12V supply; compact form factor for flexible mounting How it solves common problems Eliminates the need for large AC pumps or stationary plumbing when you need a small, portable source of water movement. Selfpriming action avoids manual priming steps, making startup quicker and easier for nontechnical users. The waterproof cover helps protect the motor from splash and moisture, extending service life in exposed installations. Use cases Mobile and automotive: Portable water transfer, small wash systems, or auxiliary pumps for vehicles and boats powered by a 12V battery. Hobby and home projects: Tabletop fountains, small garden water features, model boat bilge pumps, and DIY hydroponic or circulation systems. Offgrid and remote tasks: Water circulation or transfer on camping trips, solarpowered setups, or remote equipment cooling where AC power is not available. Practical notes Connect to a stable 12V DC source and observe correct polarity. Intended for water; avoid pumping abrasive or viscous fluids. For longevity, avoid prolonged dry running and protect the pump from freezing conditions. Compact size makes it easy to integrate into custom enclosures; the waterproof rubber cover provides additional resistance to splashes and moisture. The DC12V R27 small mini water pump with 370 motor delivers a straightforward, durable solution for compact water transfer and circulation needs, combining selfpriming convenience with a waterproof cover for improved reliability in wet environments.
