This Micro DC 3V–3.7V self-priming peristaltic pump operates on low voltage, starts drawing liquid automatically, and can transfer water or other thin non-corrosive liquids quietly and consistently — perfect for DIY, garden, and aquarium projects.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I reverse the flow direction of this peristaltic pump?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! One of the standout features of this micro DC peristaltic pump is its reversible flow direction. Simply reverse the polarity of the power leads and the pump will move liquid in the opposite direction, swapping the inlet and outlet — ideal for draining or filling applications.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What power source does this pump require?\u003c\/h4\u003e\n\u003cp\u003eA: This pump runs on DC 3V to 3.7V, making it compatible with standard AA\/AAA battery packs, single-cell Li-ion\/Li-Po batteries, and USB power adapters with a step-down module. It's a great fit for battery-powered and Arduino\/Raspberry Pi projects.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What liquids can this micro peristaltic pump handle?\u003c\/h4\u003e\n\u003cp\u003eA: This pump is designed for water and other thin, non-corrosive liquids such as nutrient solutions, plant fertilizers, or aquarium additives. It is not suitable for corrosive chemicals, oils, or viscous fluids.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is a peristaltic pump and how does this micro DC pump work?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A peristaltic pump moves liquid by compressing a flexible tube in a rolling wave motion, which pushes fluid forward without it ever touching the pump's internal parts.
