Peristaltic Pump SJB920300A (12V B08B / 12v B08b) — 12V DC DIY Liquid Metering Pump, SelfPriming Small Water Pump (also referenced as 24V electric pump option) Why choose this pump Accurate, contamination liquid transfer: As a peristaltic metering pump, the fluid only contacts the tubing, reducing contamination risk and making it appropriate for sensitive aquarium and laboratory uses. Compact, userfriendly solution for DIY and smallsystem applications: Designed for easy integration into small water systems and portable setups where a reliable, lowvoltage pump is required. Selfpriming and reliable: The selfpriming action simplifies setup and helps maintain consistent flow without manual priming. Key benefits Prevents crosscontamination: Fluid stays inside the tubing — ideal for dosing, sampling, or repeated transfers where purity matters. Lowvoltage operation: Built for 12V DC systems (product reference also includes a 24V option in listings), making it compatible with common DC power supplies, battery systems, and aquarium controllers. Simple maintenance and tubing replacement: The peristaltic design enables quick tubing access for cleaning or replacement without disassembling the pump head. Suitable for a variety of applications: Useful wherever small, controlled liquid metering is required. Main attributes Functionality: Peristaltic liquid metering pump for controlled, repeatable transfers and dosing. Power: 12V DC operation (product listing references 24V electric pump variants; confirm required voltage at ). Form factor: Small water pump suitable for compact and DIY installations. Operation: Selfpriming design simplifies startup and operation. Model and identification: SJB920300A (12V B08B / 12v B08b), per product listing title. Compatibility and use Works with standard flexible tubing used in peristaltic setups (check tubing size compatibility before installation). Compatible with common DC power sources used in aquariums, laboratory benches, and portable systems. Designed for lowvolume, precise metering rather than flow industrial pumping. Suggested use cases 1) Aquarium dosing: Controlled delivery of supplements, trace elements, or CO2 solutions where contamination prevention and gentle flow are important for aquatic life. 2) Laboratory analysis and sampling: Metering small volumes or transferring reagents and samples where fluid isolation and repeatability are required. 3) Small water systems and DIY projects: Circulation, timed dosing, or compact fluid transfer tasks in hobbyist systems, prototype rigs, and field setups. What to check before Confirm the exact voltage requirement (12V DC is specified in the product title; some listings include 24V variants). Verify tubing size compatibility for your application. Ensure the pump's flow and pressure meet your needs for dosing or transfer (flow specifications are not provided in the title; consult the seller or product sheet if exact rates are required). Practical notes The peristaltic mechanism isolates fluid within the tubing for cleaner operation and easier maintenance. Installation is straightforward for DIY users: mount the pump securely, fit appropriate tubing, and connect to the correct DC power source. Ideal for smallscale, precise metering tasks rather than heavyduty continuous pumping. Model: SJB920300A (12V B08B / 12v B08b) Type: Peristaltic liquid metering pump Power: 12V DC (check listing for 24V variant) Features: Selfpriming, small form factor, suitable for aquarium and laboratory analysis, DIYfriendly For applications that require clean, controlled, lowvoltage liquid metering in compact systems, this peristaltic pump offers a practical and maintenancefriendly solution.
