How to choose a suitable peristaltic pump?

Three main factors influencing Peristaltic Pump selection:

How to choose a suitable peristaltic pump?

1. Inner diameter of hose (ID)

When the rotation speed is the same and fixed, the flow rate pumped by the hose with larger inner diameter is larger than that of the hose with smaller inner diameter

2. Flow range

Flow rate is an important parameter of the pump, determined by many factors, such as:

Hose bore - the larger the bore, the greater the flow

Pump head speed - the faster the speed, the greater the flow

Pulse size - the larger the pulse, the greater the flow

3. The pulse

Pulsation is an important selection parameter of peristaltic pump, which is determined by various factors, such as:

Flow range - the larger the flow, the larger the pulse.

Rotor speed - the higher the speed, the greater the pulsation;

Fluid density - the greater the density, the greater the pulsation;

(note: the above parameters should be within a reasonable range)

4 handling liquid

When choosing peristaltic pump, the application environment and the nature of the liquid to be processed are also important reference factors. The optimal peristaltic pump type and supporting hose can be selected according to the requirements of viscosity, sensitivity, corrosiveness and sanitary level of the liquid
