Dosing Pump (12V)

WORKING PRINCIPLE: The 12V 5000 RPM Peristaltic Dosing Pump operates based on the peristaltic mechanism, where a motor-driven rotor compresses and releases a flexible tube to move fluid forward. When 12V DC power is applied, rollers rotate at high speed (5000 RPM), creating a consistent flow by squeezing the tube. The liquid does not come into contact with internal mechanical components, ensuring contamination-free and precise dosing. The flow direction can be reversed by changing the polarity of the supply.
MODULE STRUCTURE: The pump consists of a DC motor, a peristaltic pump head with rollers, and a flexible tube enclosed within a durable housing (often stainless steel or high-strength material). The pump head uses a buckle or screw-thread design, allowing easy removal for cleaning and tube replacement. The structure is compact, robust, and designed for high reliability in demanding environments.
PIN CONFIGURATION: The pump has two electrical terminals: Positive (+) – Connect to the 12V DC supply, Negative (−) – Connect to ground. Reversing polarity will reverse the flow direction.
INTERFACE CONNECTION: The pump operates on a 12V DC power supply (typically 10–14V range) and can be controlled using microcontrollers through motor drivers, relays, or PWM controllers for speed and flow adjustment.
OUTPUT FUNCTION: The pump provides precise and adjustable liquid dosing with flow rates ranging from approximately 1.5 mL/min to 120 mL/min (or up to ~5 L/hour depending on configuration). It ensures smooth, accurate, and pulsation-minimized fluid delivery.
OPERATING VOLTAGE: 10V – 14V DC (Nominal: 12V)
SIGNAL CONDITIONING: Flow rate control is achieved using PWM (Pulse Width Modulation) to regulate motor speed. Driver circuits or motor controllers are used for stable operation, direction control, and automation in dosing systems.
