LG350FJ is a peristaltic pump with a high large flow. It can switch the transmission mode and distribution mode by adjusting the key position and adapting to different working environments. It is installed with a KZ50 pump head and the maximum flow can reach 33L. Digital knob adjustment, and two-way large torque. The current flow or speed is displayed through a 4-digit LED, and the liquid volume can be calibrated. It supports the RS485/MODBUS communication protocol, and the knob adjusts the parameters. The operation is simple and convenient.


• By adjusting the key position, the two modes of transmission or distribution can be switched.

• Quick cleaning, filling and emptying of pipes.

• It can automatically save the control parameters when the last power fails.

• After setting the target flow, input the actual flow value, and the system will automatically perform flow correction.

• Support RS485/MODBUS communication protocol, the protocol can also be customized according to customer needs.

• KZ50 pump head can be installed, the maximum transmission is 33L.


It is used in industrial fermentation, fluid transportation such as superplasticizers and admixtures, and is suitable for large-flow sub-packaging environments.

Test conditions: 

1. Flow data testing environment for room temperature 20-25 ℃, relative humidity is not more than 80%, altitude is not more than 1500 meters.

2. The test is measured using a straight-through tube, a suction range of 0.5 meters, the head is not more than 0.5 meters, and the total length of the tube is not more than 1.5 meters (inlet end + outlet end + test end).

Note: The test environment for flow data is normal temperature and pressure, and the test fluid is water. The values are for reference only, please refer to the actual situation.
