Micro-speed Variable Peristaltic Pump with Stepper Motor for Chemical Dosing

This micro-speed variable peristaltic pump is a precision fluid transfer device focused on micro-speed precision, constant flow stability, and contamination resistance, specially designed for micro-volume fluid transfer in laboratories, biopharmaceuticals, chemical engineering, environmental protection and other fields.Equipped with a high-precision stepper motor, it supports ultra-low micro-speed operation of 0.1 rpm, with a flow accuracy of ±0.5%, enabling precise constant flow delivery from nanoliter to milliliter levels, pulse-free and backflow-free. Based on the non-contact hose transfer principle, the fluid only comes into contact with the hose, completely eliminating medium contamination and pump corrosion, making it suitable for various special media such as acid-base solutions, biological reagents, viscous liquids, and particle-containing suspensions.The product supports stepless speed regulation, forward/reverse switching, and is equipped with multiple modes including timed quantitative delivery and continuous operation, and can also achieve pipeline cleaning, realizing multi-functionality in one machine. The whole unit is compact and lightweight, operates quietly (below 40 dB), and is easy to install. It also has built-in overload protection, supporting 24-hour continuous trouble-free operation, and daily maintenance only requires hose replacement, resulting in extremely low maintenance costs.Widely applicable to scenarios such as laboratory precision metering, biopharmaceutical reagent transfer, chemical micro-dosing, and environmental water sample collection, it is an ideal choice for achieving micro-volume, precise and safe fluid transfer.
