The BT101S Variable Speed Peristaltic Pump provides a flow range from 0.0001 to 720 mL/min with variable pump heads and tubing. In addition to the basic functions such as reversible direction, start/stop, full speed (for fast cleaning), and speed adjustment, it also offers quantitative liquid delivery at regular intervals through the "easy dispensing key". With the RS485 MODBUS interface, the pump can be controlled effectively by an external device, such as a computer, human-machine interface or PLC.

Functions and Features

  • Four digits LED indicator displaying speed, the internal control, external control, footswitch and other working modes.
  • Membrane keypad operation.
  • Basic functions include reversible direction, start/stop, full speed, speed adjustment and operating parameters automatic saving.
  • Easy dispensing function, repeats liquid dispensing by time or volume.
  • High torque output, compatible with various types of pump heads with single or multiple channels.
  • The circuit board with conformal coating makes it dust-proof and moisture-proof.
  • Anti-interference feature, wide input voltage range for complex power environment.
  • External on/off voltage signal controls the start/stop, reversible direction and easy dispensing function, and optically coupled isolator.
  • External analogue adjusts the rotating speed.
