description

The LBT103S speed-variable peristaltic pump utilizes a high-quality closed-loop stepper motor drive, offering a speed range of 0.1～100rpm, speed accuracy <±0.2%, and a single-channel flow range of 0.0001～480ml/min. Remote control and real-time operational status monitoring are accessible via dedicated APP software. With RS485 communication and support for the MODBUS protocol, the pump integrates with upper-level control systems including computers, single-chip microcomputers, PLCs, frequency converters, and human-machine interfaces through multiple signal modes to achieve systematic centralized control.

features

• Powered by a high-quality closed-loop stepper motor drive, ensuring precise speed control, stable operation, and high-accuracy fluid transfer.

• Supports essential operations including start/stop, speed adjustment, direction reversal, full-speed operation, and power-down state memory.

• Allows configuration of running time, interval time, and cycle count parameters to meet requirements for timed, quantitative liquid dispensing and flow testing.

• Features slow-speed stop and back-suction functions, effectively preventing liquid dripping upon machine shutdown.

• Integrated with the LF-LED-OS software system, this pump comes with a high-resolution dot-matrix LCD display. It supports Chinese-English language switching, with straightforward parameter configuration and intuitive operational status visualization.

• Equipped with an industrial membrane keypad for simple, convenient operation and exceptional durability.

• Offers keypad lock functionality to prevent accidental misoperation.

• Provides an RS485 communication interface with MODBUS protocol support, allowing easy configuration of communication parameters and seamless connection with various control devices.

• Enables remote start/stop, speed adjustment, and timed operation via dedicated APP software. It also includes monitoring features such as stop alarm and pump tube replacement reminder (optional).

• Supports external analog speed adjustment, external start/stop control, direction reversal control, and physical isolation of external control signals.

• Compatible with a range of high-performance pump heads, enabling flexible combinations of pump heads and drives.

• Boasts a streamlined injection-molded shell design that is simple, aesthetically pleasing, and easy to clean.

• Its circuit board is coated with a conformal layer for dust and moisture resistance.

• Delivers superior anti-interference performance and accommodates a wide input voltage range, making it suitable for complex power supply environments.

• Optional features include blockage rotation alarm and leakage alarm.

• Can be connected to a thermal printer for real-time printing of operational parameters (optional).
