Metal peristaltic micro pump — compact, precise, and ready to integrate Key benefits Compact size: metal construction in a 15.7 x 8 mm footprint fits tight spaces and small assemblies without sacrificing durability. Precise micro dosing: designed for micro-volume fluid delivery with a 0.5 ml resolution, ideal when accurate small amounts matter. Low-voltage operation: runs efficiently on 3–5 V, giving flexible power options for battery-powered systems and low-voltage controllers. Reliable self-absorbency: self-priming capability simplifies setup and reduces the need for external priming steps. Repeatable control: driven by an 8 mm stepper motor (two-phase, four-wire) for predictable, controllable fluid delivery. Ready to use: each pump is individually packaged so you receive a single, protected unit ready for installation. Features and technical details Material: metal body for robustness and heat resistance while keeping a small form factor. Dimensions: 15.7 x 8 mm — suited for space-constrained applications. Voltage: operates across 3–5 V. Motor: 8 mm stepper motor, two-phase, four-wire configuration for precise step control. Delivery: micro volume delivery capability of 0.5 ml per dosing action. Packaging: individually packaged pump unit included with each purchase. How this pump solves common problems Space limits: its tiny metal body lets you add controlled fluid dosing where larger pumps won’t fit. Setup complexity: self-absorbency reduces priming hassles and speeds installation. Inconsistent dosing: stepper-driven peristaltic action gives repeatable micro-volume transfers without direct contact between pump mechanics and fluid. Low-power needs: the 3–5 V range supports low-voltage projects and portable equipment. Practical applications (use scenarios) Laboratory prototyping and microfluidics: precise reagent dosing and controlled small-volume transfers for bench experiments and device development. Automated hobby and electronics projects: integration with microcontrollers and stepper drivers for controlled dispensing in DIY machines, ink/dye systems, or micro-dosing rigs. Aquaculture and small-scale dosing systems: accurate delivery of additives or supplements where compact size and low power are important. What you get One individually packaged metal peristaltic pump unit, 15.7 x 8 mm, 3–5 V operation, 8 mm two-phase four-wire stepper motor, capable of 0.5 ml micro-volume delivery. Compatibility note The pump is driven by a standard two-phase, four-wire stepper motor arrangement and operates within a 3–5 V supply range. Use appropriate stepper drivers and control signals to achieve precise dosing.
