Designed to handle both viscous and non-viscous liquids — including ink, water, and other fluid media — this dosing pump delivers reliable, consistent liquid transfer through a gentle squeezing action on its internal silicone tubing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMade in Mainland China.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch3\u003eHow It Works\u003c\/h3\u003e\n\u003cp\u003eThe pump operates via three internal rollers that alternately compress a silicone tube, creating a peristaltic action that moves liquid through the system without direct contact between the fluid and the motor components. The 500-series DC motor supports both forward and reverse rotation, giving you the flexibility to control the direction of liquid flow. This makes it suitable for dosing, sampling, liquid dispensing, and experimental setups.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual Voltage Support:\u003c\/strong\u003e Operates at DC 5V (0.3A) or DC 6V (0.35A) for versatile power compatibility\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMetal Brush 500 Motor:\u003c\/strong\u003e Capable of forward and reverse rotation for bidirectional liquid flow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThree-Roller Pump Head:\u003c\/strong\u003e Smooth peristaltic squeezing action for consistent liquid transfer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWide Liquid Compatibility:\u003c\/strong\u003e Suitable for viscous and non-viscous fluids including ink, water, and similar lab liquids\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlastic + Metal Construction:\u003c\/strong\u003e Durable build designed for DIY projects, lab testing, and experimentation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompact \u0026amp; Lightweight:\u003c\/strong\u003e Ideal for integration into small-scale devices, Arduino projects, and benchtop setups\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDIY-Friendly Design:\u003c\/strong\u003e The pump head cover can be carefully pried open to reposition internal plastic retaining particles if needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVoltage (Option 1)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDC 5V — Working Current: 0.3A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVoltage (Option 2)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDC 6V — Working Current: 0.35A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMotor Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e500 Metal Brush Geared DC Motor\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePlastic + Metal (Silicone Tube Interior)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePackage Contents\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 × Micro Peristaltic Pump\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBattery Included\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOrigin\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMainland China\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eUsage Tips\u003c\/h3\u003e\n\u003cp\u003eFor best results, always use the end of the pump with the \u003cstrong\u003eplastic retaining particles as the inlet\u003c\/strong\u003e.

Because the liquid only contacts the internal silicone tube and not the motor components, it is suitable for a broad range of liquid transfer applications in DIY and laboratory settings.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can the pump run in reverse to change the flow direction?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — the 500-series DC motor supports both forward and reverse rotation. However, it is strongly recommended to always use the end of the pump with the internal plastic retaining particles as the inlet side, regardless of flow direction. This prevents the silicone tube from being displaced and the pump head from jamming. If you need to reverse the inlet\/outlet, you can carefully open the pump head cover and reposition the plastic particles manually.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What power supply do I need for this peristaltic pump?\u003c\/h4\u003e\n\u003cp\u003eA: The pump operates on DC 5V at 0.3A or DC 6V at 0.35A. It is compatible with standard USB power banks (5V), regulated lab power supplies, or Arduino\/microcontroller power sources. No batteries are included.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What liquids can this micro peristaltic pump handle?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This peristaltic pump is designed for both viscous and non-viscous liquids, including water, ink, and similar lab-grade fluids.
