R280 Water Pump Electronic Starter — 3.7V · 1.8 L/min · Large Flow Diaphragm SelfPriming Pump Key benefits Reliable start every time: the electronic starter gives smooth, consistent activation so the pump is ready when you need it. Ready for portable power: designed for 3.7V operation, making it suitable for singlecell lithium battery packs and other lowvoltage DC sources. Efficient water transfer: a largeflow diaphragm design delivers up to 1.8 liters per minute for faster filling, circulation, or drainage. Selfpriming convenience: eliminates the need for manual priming, so the pump can draw fluid from a dry line or reservoir without extra setup. Gentle, leakresistant pumping: diaphragm operation provides dependable, splash flow with good resistance to backflow. What it does (functionality) Pumps water and other compatible fluids using a diaphragm mechanism for steady, pulseminimized flow. Selfpriming suction allows the unit to start drawing liquid from a dry intake without external priming. Electronic starter controls the initial operation for consistent startup behavior. Key specifications and attributes Model: R280 Operating voltage: 3.7 V DC Maximum flow: 1.8 L/min (large flow for the size and voltage class) Pump type: diaphragm pump Feature: selfpriming suction Feature: electronic starter for reliable activation Compatibility and use considerations Designed for 3.7V DC systems — ideal for singlecell Liion battery packs or compatible lowvoltage power supplies. Confirm your power source matches the 3.7V requirement before installation. Suitable for water and similarly compatible fluids; check fluid compatibility for aggressive chemicals before use. For performance, follow installation guidance for inlet/outlet connections and avoid running dry for prolonged periods unless the design permits it. Typical applications Portable water transfer and camping: move water from containers to cooking or washing stations using a 3.7V battery pack for offgrid convenience. Smallscale circulation or filtration: use in compact aquarium, fountain, or water feature setups where selfpriming and steady flow are needed. DIY projects and lowvoltage systems: integrate into batterypowered sprayers, hobby irrigation, or mobile cleaning devices that benefit from a compact, selfpriming diaphragm pump. Why choose the R280 Combines a compact R280 diaphragm design with an electronic starter for dependable startups and a notable 1.8 L/min flow at 3.7V. Selfpriming capability reduces setup time and makes the pump more versatile in portable and limitedaccess applications. Engineered for lowvoltage use where steady water transfer and simple operation are required. Notes and safeuse tips Use only with compatible 3.7V power sources and within recommended operating conditions. Verify fluid compatibility and avoid pumping abrasive or corrosive liquids unless specified by the manufacturer. Refer to the product listing or manufacturer documentation for precise installation instructions, inlet/outlet connection sizes, and maintenance recommendations.
