• Robust and Durable: IP31 protection rating, suitable for various working environments.

Technical Specifications

Principle

The working principle of a peristaltic pump is similar to squeezing a fluid-filled tube with your fingers. As the drive motor turns the rollers in the pump head, the rollers alternately compress and release the pump tubing. Under the roller's compression, a 'pillow' of fluid is formed in the tube. As the roller rotates, this pillow of fluid moves forward. When the roller releases the compression, the tube returns to its original shape due to its elasticity, creating a vacuum that draws in new fluid. This continuous cycle results in a smooth, steady fluid transfer. Since the fluid only comes into contact with the inner wall of the tubing, cross-contamination is avoided.

Procedure

1. Install the tubing: Open the pump head, place the appropriate peristaltic pump tubing between the rollers and the housing, then close and secure the pump head.
2. Connect the power supply: Connect the power cord to an AC100V to AC250V power outlet.
3. Power on and set up: Press the power switch. Use the knob on the panel to set the desired speed.
4. Set direction: Use the "Forward/Reverse" key to set the fluid direction as needed.
5. Start pumping: Press the "Start/Stop" key to begin operation. The speed can be adjusted at any time with the knob to change the flow rate.
6. Full speed purge/prime: Press and hold the "Full Speed" key, and the pump will run at maximum speed, suitable for quickly purging or priming the line.
7. Timed operation: Enter timing mode, set the desired duration, and press the start key to begin timed dispensing.
8. Stop and power off: After completing the operation, press the "Start/Stop" key to halt the pump, then turn off the power.

Advantages

• Contamination-Free: The fluid only contacts the inner wall of the tubing, not the pump body, ensuring high-purity transfer.
• Simple Maintenance: The only part that requires replacement is the tubing, a quick and easy process that requires no special tools.
• Low Shear Force: Ideal for transferring shear-sensitive fluids, such as live cells and proteins.
• Strong Self-Priming: Can start without priming and can run dry without damaging the pump.
• High Metering Accuracy: Achieves high-precision fluid metering and dispensing by accurately controlling speed and time.
• Reversible Flow: The direction can be easily reversed for fluid suction and drawback.
