Compact peristaltic selfpriming pump designed for small water transfer and dosing tasks. Ideal where gentle, contamination pumping and easy maintenance are required. Available in 12V operation and shown with model identification 2021 (Kphm100ha3 24v) B10 Kphm100ha3 24v. Key benefits Clean, noncontact pumping: Fluids only contact the tubing, reducing contamination and simplifying cleaning or tubing replacement. Selfpriming, mini form factor: Starts and pumps without manual priming and fits into tight spaces where larger pumps cannot. Reliable for smallvolume tasks: Built to handle continuous or intermittent small water transfers common in hobby, lab, and light industrial projects. Simple installation and replacement: Compact design makes it straightforward to install, service, or swap tubing when needed. Main attributes Pump type: Peristaltic pump — positive displacement action that moves fluid by compressing tubing in sequence. Power options / model reference: Described as a 12V small water pump; listing and labeling also reference model 2021 (Kphm100ha3 24v) and B10 Kphm100ha3 24v. Size and form factor: Small / mini pump suitable for compact installations or portable setups. Functionality: Selfpriming capability for easy startup without external priming assistance. Maintenance: Tubingonly fluid path enables fast service and low contamination risk. How this pump solves common problems Eliminates crosscontamination: Because the fluid runs through replaceable tubing, the pump body stays isolated from the liquid. Simplifies installation in tight spaces: The mini size allows mounting in compact equipment, cabinets, or enclosures. Removes the need for manual priming: Selfpriming design makes setup faster and operation more reliable after interruptions. Practical use cases Aquarium and hydroponics: Metering nutrient or dosing additives precisely without introducing contaminants into the system. Portable water transfer and smallscale dispensing: Compact solution for camping, field tests, or small beverage dispensing where space and power are limited. Laboratory and hobby projects: Transferring small amounts of water or reagents where tubingbased isolation and easy tubing replacement are advantageous. Notes for buyers Confirm the required supply voltage for your application; the listing references 12V operation and the model designation Kphm100ha3 24v. Verify the correct voltage/model before installation to match your power source. Replacement tubing and basic maintenance are recommended to preserve performance over time. This compact peristaltic, selfpriming mini water pump is intended for users who need a small, contaminationconscious solution for controlled water transfer and dosing in tight spaces.
