12V DC Peristaltic Dosing Pump – Aquarium & DIY Lab
12V DC Peristaltic Dosing Pump – Precision Fluid Delivery for Aquariums, Labs & DIY Projects
Take precise control of fluid dosing with this compact 12V DC Peristaltic Dosing Pump. Engineered with a three-roller pump head and transparent silicone tubing, this pump delivers smooth, consistent flow — making it ideal for aquarium dosing, laboratory experiments, biochemical analysis, fine chemicals, biotechnology applications, and a wide range of DIY builds.
Key Features
- Screwless Design: Tool-free disassembly for fast, hassle-free cleaning and maintenance.
- Clockwise & Counter-Clockwise Operation: Simply reverse the positive and negative power connections to switch the direction of flow — no additional hardware needed.
- Self-Priming Capability: Starts pumping without manual priming, saving you time and effort.
- No Valves or Seals: Hose replacement is quick and straightforward, keeping downtime to a minimum.
- Wide Voltage Compatibility: Operates on 12V or 24V DC power supplies (motor rated DC 12V; confirm your power supply output before use at 24V).
- Three-Roller Pump Head: Reduces pulsation for a smoother, more consistent flow rate.
- Transparent Silicone Tubing: Allows you to visually monitor fluid flow at a glance.
- Compact Footprint: Measures just 67.5 × 54.5 × 41 mm (approx. 2.66 × 2.15 × 1.61 in) — fits easily into tight spaces.

Frequently Asked Questions
Q: What is a peristaltic dosing pump and how does it work?
A: A peristaltic dosing pump moves fluid by compressing and releasing a flexible silicone tube using rotating rollers. The squeezing action pushes liquid forward in a precise, metered flow — no fluid ever contacts the pump mechanism itself, making it easy to clean and ideal for sensitive or corrosive liquids.
Q: Can I use this pump with a 24V power supply?
A: The motor is rated at DC 12V. The listing notes 12V/24V compatibility, but always verify your specific power supply output and motor tolerance before operating at 24V to avoid overheating or damage.
Q: How do I reverse the flow direction of the pump?
A: Simply swap the positive and negative terminals on your DC power connection. Reversing polarity switches the motor between clockwise (CW) and counter-clockwise (CCW) rotation, which reverses the direction of fluid flow through the tubing.
Q: Is the pump self-priming?
A: Yes. This peristaltic dosing pump features self-priming capability, meaning it can draw fluid into the tubing automatically when powered on — no manual filling of the tube is required before startup.
Q: What size tubing does the pump use?
A: The pump comes with a transparent silicone tube. Refer to the product images for exact inner and outer diameter measurements to ensure compatibility with your system's fittings.
