WT300S Basic Variable Speed Peristaltic Pump

Description

WT300S pump can work with up to 4 pump heads because of the large torque DC brushless motor drive and it's maintenance free. It has basic functions such as reversible direction, start/stop, full speed (for fast cleaning) and adjustable speed. The start/stop, reversible direction, speed adjustment functions can be controlled by external control signal, besides it also has time dispensing function. With RS485 MODBUS communication interface, the pump is easy to communicate with external device, such as PC, HMI or PLC.

Functions and Features

• Four digits LED indicator display working speed.
• The LED indicator displays the internal, external control, footswitch etc 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.
• Can 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 the 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 and easy dispensing function, optically coupled isolator; external analog control signal adjusts the rotate speed.
• RS485 MODBUS interface, easy to be controlled by external device.
• Optional footswitch or timer for dispensing fluid.
