WT300S Variable Speed Peristaltic Pump
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
- LCD displays rotating speed and operating mode.
- Membrane keypad.
- Reversible direction, start/stop control and adjustable speed.
- Time dispense mode: automatically dispense by setting the duration for each dose, lag time between doses and the number of cycles.
- High torque output, able to drive multi-channels and various types of pump heads.
- Stainless steel housing, easy to clean, excellent resistance to corrosion of 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.
- RS485 MODBUS interface, easy to be controlled by an external device.
- Optional footswitch or timer for dispensing fluid.
