WT300S Basic Variable-Speed Peristaltic Pump

WT300S series peristaltic pump adopts DC brushless motor drive which is large torque, free maintenance, more powerful, can cascade multiple pump heads. Has basic function such as start/stop, reversible direction,full speed, adjust speed and state memory. Control the start/stop, reversible direction, adjusts the speed via external analog quality, the time dispensing function. RS485 communication, MODBUS protocol is available, easy to connect other equipments such as computer.

Flow: 1.2~3850mL/min
Max: 2 Channels

Functions and Features

WT300S Suitable Pump Heads and Tubing, Flow Parameters

Drive type Pump head Ch Tubing size Flow rate per channel (mL/min)
WT300S KZ25 1,2 15#24#35#36# 93~3850
KZ25-L 1 15#24#35#36# 93~3850
GN10 1 2.48×0.76




Above flow parameters are obtained by using silicone tube to transfer pure water under normal temperature and pressure, in actually it is effected by specific factors such as pressure, medium, etc. Above for reference only.
