Micro DC Peristaltic Self-Priming Water Pump – Compact & Reversible

Meet the 130 Micro DC Peristaltic Self-Priming Pump — a versatile, low-voltage liquid pump designed for DIY projects, lab setups, aquariums, hydroponics, and small-scale fluid transfer applications. Running on just 2–5V DC (rated at 3.7V), this compact pump can move liquids in either direction by simply reversing polarity, giving you full control over inlet and outlet flow.

Key Features

Self-Priming: Starts pumping without manual priming — simply power it on and it draws liquid automatically.
Reversible Flow Direction: Swap the inlet and outlet by reversing the motor polarity — ideal for flexible plumbing setups.
Low Voltage Operation: Compatible with 2–5V DC power sources, making it perfect for battery-powered or microcontroller-based projects (Arduino, Raspberry Pi, etc.).
Peristaltic Design: Liquid only contacts the tubing — not the pump internals — keeping your fluid uncontaminated and the pump easy to clean.
Compact & Lightweight: The 130-motor form factor fits easily into tight enclosures and portable builds.
Quiet Operation: Low noise output for use in indoor and sensitive environments.

Frequently Asked Questions

Q: What voltage does this peristaltic self-priming pump operate on?

A: This micro DC pump is rated at 3.7V and is compatible with voltage inputs ranging from 2V to 5V DC. It draws a no-load current of just 0.15A, making it suitable for battery-powered and microcontroller-driven projects.

Q: Can I reverse the flow direction of this pump?

A: Yes! One of the standout features of this peristaltic pump is its reversible flow direction. Simply reverse the polarity of the DC power input to swap the inlet and outlet — no replumbing required.

Q: Is this pump suitable for use with an Arduino or Raspberry Pi?

A: Absolutely. The low voltage (2–5V) and low current draw make this pump an excellent choice for microcontroller-based DIY builds including Arduino and Raspberry Pi projects, automatic plant waterers, and liquid dispensers.

Q: Does the liquid come into contact with the pump motor?

A: No. Thanks to the peristaltic design, fluid only travels through the flexible tubing and never contacts the pump's internal motor components. This keeps your liquid uncontaminated and makes cleaning straightforward.
