The Small Peristaltic Pump DC 12V SelfPriming Pump Liquid Pump Aquarium Reversible Metering Pump is a compact liquid transfer device built for reliability and ease of use. Powered by 12V DC, it provides selfpriming operation and a reversible flow, making it suitable for precise metering and dosing tasks in smallscale setups. Key Benefits Selfpriming design speeds up setup and reduces manual priming requirements, enabling quick deployment in hobby projects and small systems. Reversible flow adds flexibility, allowing you to switch liquid direction for metering, sampling, or backflushing as needed. Meticulous dosing capability supports controlled transfer of liquids, aiding precise budgeting of additives, nutrients, or medications. Compact form factor fits in tight spaces such as cabinet shelves, aquariums, or compact DIY rigs. Simple 12V DC operation integrates with common power supplies and hobby electronics without specialized equipment. Peristaltic pumping minimizes contamination risk, because the liquid only contacts the interior of the tubing, keeping fluids isolated from the pump mechanism. Key Attributes Functionality: Peristaltic pump with selfpriming capability and reversible flow for metering and dosing tasks. Compatibility: Operates on 12V DC power; suitable for a range of liquids used in aquarium, hydroponic, and DIY applications. Size: Small and compact design intended for use in confined or cluttered spaces. Material: Built for general liquid transfer with tubingbased contact; designed to handle common hobbyist liquids in shortterm or routine use. Performance: Designed for reliable, lowmaintenance operation in everyday liquid transfer applications; piping and tubing selection influence overall flow characteristics. Applications Aquarium dosing and automatic liquid management: dosing additives, conditioners, or supplements with precise refill or off routines in small aquariums. Hydroponics and nutrient dosing: smallscale nutrient solution metering for home gardens or hobby greenhouses. DIY projects and basic laboratory tasks: transferring reagents or samples in controlled amounts, or backflushing lines in compact test rigs. Notes Suitable for short to mediumterm use in hobby and lightduty professional tasks. Ensure proper tubing compatibility with the liquids to be pumped and follow safety guidelines for electrical connections in wet environments. Verify power supply specifications to match the 12V DC requirements for safe operation.
