WT300S Basic Speed
» Product introduction
This pump adopts DC brushless motor drive which is large torque, free maintenance, can cascade four pump heads .Has basic functions such as reversible direction, start/stop, full speed (fast cleaning) and adjust speed. Control the start/stop, reversible direction, adjusts the speed via external analog quality, and adds the time dispensing function.RS485 interface, as adopting the MODBUS communication protocol, the pump is easier to be connected with other equipments, such as computer, human machines interface and PLC.
