Peristaltic Liquid Pump with Silicone Tubing - 5V to 6V DC Power

This peristaltic pump moves liquid by squeezing flexible silicone tubing with a rotating clover-pattern roller mechanism — the pump never directly contacts the fluid. This makes it well suited to food, beverage, gardening, and sterile applications where contamination must be avoided.

The pump is driven by a geared DC motor operating at 5–6 V. It self-primes from up to 500 mm below the fluid level and can be driven with PWM for variable flow rate control. Reversing the motor polarity reverses the flow direction. Compatible with basic transistor switching or motor driver ICs such as the L293D.

Key Features

• Peristaltic Design – Fluid stays inside the tubing; pump never contacts the liquid
• Self-Priming – Draws water from up to 500 mm below
• Reversible Flow – Swap motor polarity to change direction
• PWM Speed Control – Adjust flow rate with pulse-width modulation
• Geared DC Motor – High torque for reliable fluid movement
• Silicone Tubing Included – Pre-installed with two 500 mm extension tubes and barbed connectors
