Why Choose a Peristaltic Pump?
Peristaltic pumps work by squeezing a flexible tube to move liquid through — the fluid never contacts the motor or internal gears. This design provides self-priming capability, gentle handling of sensitive liquids, and easy tube replacement for maintenance. Learn more about fluid handling and pump safety principles at CPSC.gov.
For makers and engineers interested in precision flow control, the National Institute of Standards and Technology (NIST) offers extensive resources on measurement and flow standards.
Frequently Asked Questions
Q: What voltage does this micro peristaltic dosing pump operate at?
A: The pump has a rated operating voltage of DC 3V – 3.7V, with a broader applicable voltage range of DC 2.4V – 4.2V, making it flexible for use with common Li-ion batteries and low-voltage DC power supplies.
Q: What is the planetary gear motor and why does it matter for a micro dosing pump?
A: The M20 miniature planetary gear reduction motor (10mm outer diameter) provides torque multiplication in a tiny footprint. The planetary gear arrangement distributes load evenly across multiple gears, resulting in quieter operation, higher efficiency, and longer motor life compared to standard spur-gear motors — essential qualities for a precision dosing pump.
Q: What types of liquids can this peristaltic pump handle?
A: Because of its peristaltic (squeezing) mechanism, the liquid only contacts the flexible inner tube — never the motor or pump body. This makes it suitable for water, nutrient solutions, light chemicals, and other liquids compatible with the tubing material. Always verify chemical compatibility with the specific tubing before use with corrosive fluids.
Q: Is this pump suitable for aquarium dosing systems?
A: Yes. Its compact size, precise 3-roller metering, and isolated-fluid design make it an excellent choice for aquarium additive dosing, reef tank nutrient delivery, and other small-volume liquid dosing applications.
