Key benefits Compact allmetal mini peristaltic pump with an 8 mm stepper reduction motor for durable, longlasting operation and precise dosing. Bidirectional flow capability allows you to change water flow direction without reconfiguring hardware. Copper roller pump head and allmetal gear reduction ensure reliable performance and consistent pumping in demanding environments. Low power, 5V DC operation with a small form factor (weight 5.2 g) suitable for tight spaces and portable setups. Specifications Pump tube: 2.5 mm silicone tube Motor: 8 mm twophase fourwire stepper motor Phase resistance: 22 ohms Weight: 5.2 grams Nominal voltage: DC 5V Rated current: 150 mA Flow performance: maximum flow rate 0.5 mL/min, as tested with our store's stepper motor drive board Construction: allmetal mini peristaltic pump with metal gear reduction pump head group Head features: copper roller peristaltic pump head Direction: supports changing the direction of water flow in both directions workmanship: standards of manufacture What makes it stand out Allmetal design and copper roller head provide robustness and durability for repeated use and precise control. Small, lightweight package tailored for precision dosing projects, microfluidics experiments, and compact automation setups. Clear specification for ease of integration: 5V DC operation, 150 mA current, and a defined maximum flow rate on a standard drive board. Performance notes The stepper motor can achieve precision quantitative output; exact performance depends on the drive hardware and control method used. Applications and use scenarios Laboratory microfluidics and chemical dosing: use this pump for smallvolume, repeatable fluid delivery in experiments requiring accurate microfluidic control. Prototyping and automation: integrate into compact automation rigs or test benches where a precise, lowflow liquid pump is needed in a tight space. Educational demonstrations and hobby projects: suitable for teaching stepperdriven peristaltic pumping principles and for building smallscale demonstration setups. Additional considerations The maximum flow rate specification (0.5 mL/min) is measured with our store's stepper motor drive board; actual flow may vary with different drivers and control signals. Ensure proper handling of the 2.5 mm silicone tubing and confirm compatibility with your intended fluids and operating environment.
