Variable-Speed Peristaltic Pump

Functions and Features

LCD displays rotating speed and working 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 number of cycles.
0.5% high precision rotating speed control with 0.1 rpm speed resolution when speed is between 0-100 rpm, 1 rpm speed resolution when speed is between 100-600 rpm.
External logic level signal can control start/stop, direction and dispense functions; external analog signal can adjust the rotating speed. Signal is optically isolated.
With RS485 MODBUS interface, easy to communicate with external device.
Internal double-layer isolation structure; circuit board with conformal coating makes the pump dust-proof and moisture proof.
Anti-electromagnetic interference feature, wide input voltage range for complex power environment.
Stainless steel enclosure, easy to clean, resistant to the corrosion of the acid, alkali, sodium and organic solvents.
