Dual-Channel Peristaltic Pump - 0.211-3600 mL/min per Channel Variable-speed Industrial Tubing Pump

Introduction

The peristaltic pump offers precise fluid delivery by compressing flexible tubing, making it ideal for applications requiring contamination-free and accurate fluid transfer, such as in laboratories, medical devices, and pharmaceutical industries.
The U.S. Solid M6-3L peristaltic pump is compatible with the DZ25-3L pump head and various tubing sizes, including 15#, 24#, 35#, and 36#.
It offers a speed range from 0.1 to 600 rpm, which results in a flow rate range of 0.211 to 3600 mL/min. Powered by a closed-loop stepper motor, the pump delivers high-output torque, along with significant suction stroke and lift capabilities. Speed adjustments can be made manually via a digital knob or automatically through the external control interface, offering increased flexibility and ease of use.
This listing includes a dual-channel peristaltic pump equipped with two DZ25-3L pump heads.

FAQ

1.How many channels does this peristaltic pump have?

This is a dual-channel peristaltic pump with 2×DZ25-3L pump heads. The pump settings apply to both channels and are not independently controllable; all values are per channel.

2.What type of peristaltic pump is this? What are its main functions?

As the most basic type of peristaltic pump, it supports core functions including speed adjustment, start/stop control, direction reversal, and full-speed operation. Additionally, the M6 series offers a simple timing function.

3.Does it have a timing function?

Yes, it has a basic timer. You can set the duration (max 999s), and the pump will stop automatically when the time runs out. The timer remembers the last set value. Note: It can only be set via the buttons (not by external control), and it does not support scheduling by specific date or time. Quick setup steps (refer to the manual for details):

• Press and hold the Timer button for 3–5 seconds.
• Set the desired duration by turning the adjustment knob.
• After setting the time, press the Timer button again to exit and adjust the speed as needed.
• Press the Timer button once more to start the timed run, after which the pump will stop automatically.

4.How to install the tubing?

Clamp the tubing into the tubing clamps

• The side of the tubing clamps, which marks the size of the tubing, such as "36", needs to be faced outward.
• The distance between the two sharp corners of the tubing clamps is suggested to be set as 90-95mm.
• If you think it's too tight, it doesn't matter to expand a little bit. If you think it's too loose, it doesn't matter to narrow a little bit.

5.Does it support external control?

Yes. Please note that the button and knobs will no longer work after switching to external control mode. In this mode, only start/stop, direction reversal, and speed adjustment can be controlled externally—the timing function is not supported. After pressing the external control button, you can check the indicator lights for start/stop, direction, and speed. If an indicator is on, the corresponding function can be controlled externally. The indicators may light up in different combinations: one on, two on, or all three on. If none of the indicators are lit, the unit is not in external control mode.

6.Which types of tubing are compatible with this peristaltic pump?

Applicable tubing sizes are 15#, 24#, 35# and 36#. The kit includes one piece of each size, with a length of 4 meters per piece. Common-size tubing information is provided below for reference only and does not imply full compatibility with all listed sizes.

7.What are the differences between the M6-3L, M6-6L, and M6-12L in the M6 series?

The functions are basically identical; the main difference lies in the maximum flow rate they support.
