BT100S Basic Variable-Speed Peristaltic Pump

BT100S series of peristaltic pumps adopts imported core processor,high quality stepper servo motor drive, speed control accuracy is±0.2%. Through the Lead Fluid APP software, the pump can be remotely controlled and the running status can be monitored in real time. RS485 communication, Modbus protocol, can be connected to the upper computer such as computer, single chip microcomputer,PLC, frequency converter, man-machine interface through a variety of signal modes, to achieve systematic centralized control.

Flow: 0.0002-720ml/min
Max: 4 Channels

Functions and Features

  • LF-LCD-OS software system, high definition lattice LCD display, switching between Chinese-English interface, simple parameter setting, intuitive state display.
  • High-quality and high-torque stepper servo motor drive, speed accuracy, wide range, operation stability, high-precision flow transmission.
  • Industrial mask key operation, simple and convenient, high durability.
  • LF-Easy Change universal design, large torque output, strong expansibility, can match various high-performance pump head.
  • Start/Stop, adjust speed, reversible direction, full speed and,state memory (power-down memory).
  • The parameters of running time, interval time and cycle times can be set to meet the requirements of timing, quantitative, liquid dispensing and flow testing.
  • Slow speed stop and suction function, which can effectively prevent the dropping of liquid when the machine stops.
  • Keyboard lock function to prevent misoperation.
  • The remote start-stop, adjust speed and timing operation can be realized by using Lead Fluid APP software. It also has monitoring functions such as stop alarm, change of pump tube and so on (optional).
