This makes it compatible with single-cell lithium batteries (3.7V), USB 5V supplies, and standard 6V DC adapters — ideal for Arduino, Raspberry Pi, and other hobbyist electronics projects.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this pump self-priming, and can it pump air as well as water?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — this is a self-priming diaphragm pump, meaning it can draw liquid up from below without pre-filling. Its diaphragm design also allows it to move air, giving it dual-function capability useful in a range of DIY applications such as small fountain systems, automated plant watering, and pressure or inflation testing rigs.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the suction lift and maximum lift height of this mini pump?\u003c\/h4\u003e\n\u003cp\u003eA: The RF-310 mini pump delivers a suction lift of at least 1 metre and a total lift (head) of at least 2 metres. These figures make it well-suited for compact liquid transfer tasks, small aquarium circulation, and garden watering automation projects.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this pump compatible with Arduino or Raspberry Pi projects?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The low voltage requirements (3.7V–7.4V DC) and low current draw (approximately 150 mA at 6V) make the RF-310 mini pump an excellent match for microcontroller-based projects. Simply control it via a small relay module or MOSFET transistor from your Arduino or Raspberry Pi output pins.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What voltage does the RF-310 mini diaphragm water pump run on?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The pump operates across a wide range of DC voltages from 3.7V to 7.4V, with a rated voltage of 6V.
