Introduction
• Small size, compact structure, beautiful appearance.
• High-quality material selection, sanitary and non-toxic, high strength, good flexibility, and excellent
resistance to chemical corrosion.
• The pump head utilizes a spring-loaded tube mounting structure that provides long tube life and
high precision flow, the proper pressure can be obtained by adjusting the pressure tube unit.
• Adjusting the pressure tube device allows obtaining the appropriate pressure.
• The tube is easy and quick to install, and it can be adapted to various specifications, meeting a wide range of application requirements.
• Suitable for low-flow applications, it can be used as an ODM matching accessory in various instruments and equipment.

For speeds above 100rpm, it is recommended to use intermittent operation. The intermittent operation mode involves running for 0.7 seconds and then stopping for 0.3 seconds.
The above data is obtained from the test of purified water with a Lead Fluid tube under normal and pressure conditions in the laboratory. This data is for reference only.
Due to pressure in actual use, temperature, medium characteristics, tube material and other specific factors, the specific situation needs to consult our engineers.
Product Structure & Usage Method
Product Structure
Component Name and Function:
1.Pump Head Pressure Block: Squeezes the tube along with
the roller assembly.
2.Mounting Plate: Connects the motor to the pump head
bracket and allows the product to be installed on other devices.
3.Motor: Provides power.
4.Tube: Made of silicone or pharmed material.
5.Tube Connector: Secures the tube in place.
Usage Method
Disassembling the Tube
Step 1: Unscrew the hand-tightened screw counterclockwise, then rotate the
pressure plate clockwise while applying downward force to remove it.
Step 2: Remove the reversing screw, then lift the pressure block
upward, and take out the tube and tube connector.
Install Tube
Reverse the order of disassembly.
