Compact, reliable diaphragm pump driven by a 370series DC motor. Designed for water suction, selfpriming operation and light vacuum tasks at low DC voltages, this pump delivers large flow in a small package—ideal for hobby, appliance , small equipment and portable fluid transfer. Why you need it Provides reliable water suction and selfpriming performance where larger pumps are impractical. Runs on common lowvoltage DC power (5V–6V), making it easy to integrate with batteries, power adapters, and simple controllers. The 370 electronic starter motor offers smoother, more consistent starts and dependable operation for intermittent or continuous use. Key benefits Selfpriming: Starts pumping without manual priming, simplifying installation and use. Large flow in a compact form: Moves a useful volume of liquid while fitting into tight spaces. Lowvoltage compatibility: Operates at DC 5V–6V for flexible power options. Vacuumcapable diaphragm action: Can be used for light vacuum or suction tasks as well as liquid transfer. Easy integration: Small, lightweight design suited for DIY projects, small appliances, and portable systems. Main attributes Functionality: Diaphragmtype water suction and selfpriming pump driven by an electronic starter 370 motor; suitable for pumping and light vacuum duties. Compatibility: Designed for DC 5V to 6V input; works with battery packs, USBstyle 5V supplies (when current is sufficient), or regulated DC adapters. Size and form factor: Compact and lightweight for use in constrained spaces; typical of small 370motor driven pumps. Performance: Emphasizes large flow relative to its size and selfpriming capability; stable start provided by the electronic starter motor. Construction and reliability: Built for routine use in hobbyist, household, and lightcommercial applications where compact, lowvoltage pumping is needed. Typical applications Portable water transfer and toppingoff: Move water between containers, fill small reservoirs, or transfer water for cleaning tasks. Small circulation and fountain systems: Provide continuous flow for desktop fountains, small aquaponic setups, or compact water features. Vacuum or suction tasks in DIY projects: Useful for simple vacuum generation for clamping, smallscale fluid sampling, or laboratorystyle demonstrations. Installation and use tips Power: Use a stable 5V–6V DC supply capable of delivering adequate current for a 370series motor. Ensure wiring and connectors can handle the motor start current. Priming and orientation: Thanks to selfpriming design, initial priming is usually not required. Install with inlet and outlet hoses secured to prevent air leaks for suction performance. Mounting: Secure the pump in a vibrationdamped position where it remains protected from prolonged exposure to dirt or debris. Maintenance: Periodically check hoses and fittings for wear or leaks. Keep the pump clean from sediment and avoid running dry for extended periods to preserve diaphragm life. What makes this pump different Combines the compact 370 motor form factor with an electronic starter and diaphragmbased selfpriming mechanism to deliver strong flow in small spaces, with the lowvoltage flexibility needed for portable and DIY applications. Compatibility checklist Power source: DC 5V–6V Motor type: 370 electronic starter motor Application type: Water suction, selfpriming pumping, light vacuum/suction use If you need a compact, lowvoltage diaphragm pump for water suction, selfpriming operation, or small vacuum tasks, this DC 5V–6V largeflow small 370 electronic starter diaphragm pump offers a practical balance of size, flow capability, and ease of integration.
