12V 8W Peristaltic SelfSuction Pump with Reversible Flow and Photoelectric Encoder Key benefits Selfsuction design removes the need for manual priming, saving time and reducing setup steps. Reversible flow lets you switch pump direction for intake or discharge, simplifying plumbing and allowing one pump to handle multiple tasks. Integrated photoelectric encoder provides reliable feedback for the peristaltic motor, improving speed conversion and control accuracy. Low power consumption at 12V and 8W makes the pump suitable for DC systems and batterypowered setups. Function and performance Peristaltic action moves liquid through flexible tubing, keeping the fluid isolated from internal components for cleaner operation and easier maintenance. Reversible motor direction supports both water in and water out functions without mechanical reconfiguration. Photoelectric encoder delivers precise rotational information to controllers, enabling smoother speed changes and better repeatability. Compatibility and installation Designed for 12V DC power systems and 8W nominal power draw. Works with standard peristaltic tubing commonly used for water transfer. Confirm tubing size with your application before installation. Compatible with motor controllers and drive electronics that accept encoder feedback for closed loop control. Size and durability Compact and lightweight form factor suitable for integration into small machines or portable setups. Fluid path is limited to tubing, simplifying cleaning and replacement while reducing contact between pump internals and transferred liquid. Practical applications Aquarium maintenance and water change systems where automated suction and discharge reduce manual handling. Hydroponics and smallscale nutrient circulation where reversible flow and precise speed control improve dosing and circulation management. Portable water transfer for outdoor equipment or vehicle systems requiring a low power, reversible pump with accurate speed feedback. What to consider before Confirm your tubing size and material compatibility with the fluids you plan to transfer. Verify that your controller or system can utilize encoder feedback if closed loop speed control is required. Ensure a 12V DC supply capable of delivering the pump start and running current is available. This 12V 8W peristaltic selfsuction pump offers flexible, controllable fluid handling with reversible flow and encoder feedback for improved conversion and operational precision.
