BT300S Speed Variable Intelligent Peristaltic Pump

BT300S High-Precision Speed-Variable Intelligent Peristaltic Pump

The BT300S is a high-performance fluid transfer solution featuring an imported core processor and a high-torque stepper servo motor drive. It delivers a wide flow range from 0.005 to 1750 mL/min with an industry-leading speed control accuracy of ±0.2%. Housed in a durable 304 stainless steel shell, it is designed for precision, stability, and intelligent integration in laboratory and industrial environments.

Key Features & Advanced Functionality

• • Intelligent Operating System: Features a high-definition lattice LCD display with a dual Chinese-English interface. Parameters are easily adjustable with an intuitive status display.

• • Precision Drive Technology: Driven by a high-torque stepper servo motor that ensures exceptional operation stability and high-precision flow transmission across a wide speed range.

• • Industrial-Grade Durability: The 304 stainless steel housing prevents erosion from organic solvents and is easy to clean. The internal double-layer isolation design provides enhanced protection against dust, moisture, and corrosion.

• • Automated Dispensing: Users can configure running time, interval time, and cycle counts to meet specialized requirements for timing, quantitative dispensing, and flow testing.

• • Anti-Drip Mechanism: Includes a slow-speed stop and suction function to effectively prevent liquid dripping when the cycle ends.

• • Smart Integration: Equipped with an RS485 communication interface and Modbus protocol. It supports remote operation via professional App software for real-time monitoring and control.

• • External Control Compatibility: Accepts various external industrial control signals (5-24V) to manage start-stop, direction, and speed adjustment via optical coupling isolation.
