Peristaltic pump selection guides

A.Tubing selection
Flow rate-Referring flow rates curve
Chemical compatibility-The tubing material must be compatible with the fluid
Fluid Temperature-Tubing applications are often restricted due to the pronounced temperature sensitivity
Suction Lift option- Shore hardness, wall thickness IDof tubing and will affect suction lift.
Tubing life-A pump tubing with a long life reduces the total cost of pump ownership.

B.Pump head selection
Flow rate-Referring flow rates curve
Tubing changing-Longer Pump Heads is easy to change the tubing
Channel-We have multi channel for choosing or you can stack the pump heads and connect their outlets together.
Chemical compatibility-Overflowed fluid will restrict the material of pump head

C.Drive selection
Flow rate- The rpm of the drive directly correlates to flow rate.
Controlling mode- Fixed or variable speed, flow rate adjusting, dispensing and external controlling for option.
Protection- Considering if air proof, water proof, dust proof is needed according to the application environment.

Syringe pump selection guides

A.How to select syringe?
Choosing the proper specification according to the volume of dispensing fluid

B.How to select Dirve?
Application dispensing mode of the fluid
Application environment and installation mode
Multi-channel and single channel of drive for option
Considering the flow rate and dispensing accuracy
Split unit syringe pump(drive unit and controller are all called drive )

Immersion test will be needed, when the chemical compatibility of the tubing is uncertain. In this test, weighed a small piece of tubing and measured its length and diameter, afterward immersed this tubing in specific liquid contained in an airtight vessel for minimum 48 hours, then record any changes to the tubing after it was rinsed and dried and measured. The softening, embrittlements or color changes of tubing mean the tubing had been affected by the specific liquid.

The tubing is compatible with the specific liquid if it survives through the test without discoloration, swelling, cracking, loss of flow or other signs of deterioration.
