FP300S-A3 Frequency Conversion Explosion-Proof Motor Peristaltic Pump

Special explosion-proof pump head design, more safety and reliable, motor comprehensive protection, wide speed range.

Flow range:0.7-33L/min

Speed range:34.5-345rpm

Pump head:PL48

Display function: Frequency converter display the Hz or flow rate (analogue)


• Industrial grade AC frequency conversion explosion-proof motor (ExdIIBT4), with special pump head, safe and reliable.

• External frequency conversion control, with functions such as adjust speed, start-stop, reversible direction, analog adjust speed, RS485 communication.

• Pump head roller adopts planetary gear transmission structure, strong power.

• The roller rotates with power to roll and rub with the hose to extend the life of hose.

• Open the cover to stop the pump function to ensure the safety of the operator.

• Elastic pressure tube structure extends pump tube life.

Stepless speed, speed range 34.5rpm345rpm, speed resolution 0.77rpm.

• Split design, the driver is separated from the frequency conversion, suitable for a variety of working environment.

• Large torque design, stable operation, max flow is 33L/min.

• IP55, suitable for complex working environmen.

• The standard frequency conversion is not explosion-proof and cannot be placed in a flammable and explosive environment.


1. Industrial grade explosion-proof frequency conversion is optional .

2. Protective shell can be installed.

3. Customizable all-in-one model.
