The WT300S High Torque Variable Speed Peristaltic Pump, powered by a maintenance-free DC brushless motor, is robust, powerful, and can be cascaded with multiple pump heads. It features fundamental operations including reversible direction, start/stop, full speed (for rapid cleaning), and adjustable speed, all controllable through external signals. The pump is further equipped with a time dispensing function. Enhanced communication capabilities are facilitated through the RS485 MODBUS interface, enabling effective interaction with external devices such as PCs, HMIs, or PLCs.

Functions and Features

  • Four digits LED indicator displaying speed, operating mode, internal/external control, footswitch control and other working modes.
  • Membrane keypad operation.
  • Reversible direction, start/stop, adjustable speed and full speed, power-off memory function
  • Easy dispensing functions, repeats liquid dispensing by time or volume.
  • High torque output, able to drive multi-channels and various types of pump heads.
  • Stainless steel housing, easy to clean, excellent resistance to the corrosion of the acid, alkali, sodium and organic solvents.
  • 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, easy dispensing function, and optically coupled isolator; external analogue control for speed adjustment.
