How to Select the Right Peristaltic Pump Model

Peristaltic pumps are composed of three main parts: the drive, the pump head and the peristaltic pump silicone tube. One, therefore, needs to consider each of these three components when choosing the right model.

 DRIVE

Revolutions per minute (rpm): The higher the speed of the drive, the higher the flow rate. The rpms of our pumps fall within one of the three ranges: 0.1-150 rpm, 0.1-350 rpm and 0.1-600 rpm. 

Operation and control: Several factors should be considered here, such as speed control (fixed or adjustable speed), flow rate calibration for a more precise flow rate, dispensing requirements, external control and availability of optional accessories. 

Protection level: Dust- and water-proof level of the drive should be taken into consideration when a peristaltic pump is to be used in a specific or challenging environment. 

PUMP HEADS

 Flow rate: This is one of the decisive factors when choosing a peristaltic pump. Different pump heads provide different flow ranges. Based on the required flow rate for an application, one can choose a pump head which meets the flow rate requirement.  

Fluid viscosity: Viscosity refers to the "thickness" of a fluid. The higher the fluid viscosity, the slower the transmission would be. When selecting a peristaltic pump, fluid viscosity must be considered. 

Number of channels: Depending on the requirement of an application, one can choose a single or multi-channel pump head.  

Chemical compatibility: The pump head material should be compatible with the fluid handled in case of a fluid spill. 

PERISTALTIC PUMP TUBING 

Chemical compatibility: As tubing is the main part that is in contact with the fluid transferred, one must check the chemical compatibility with the tubing material. 

Tubing lifespan: To avoid frequent replacement of tubing, one needs to consider the optimal size and life span of tubing to meet the flow requirement.
