Peristaltic pumps have good sealing and accuracy in transmitting liquids, but not all liquids can be transmitted. The properties of some liquids will have a certain impact on the transmission of the pump, such as the viscosity and pH value. So, what effect does the viscosity of the transmitted liquid have on the peristaltic pump?

According to experimental analysis, the greater the concentration and viscosity of the transmission liquid, the higher its adhesion and the slower the transmission. As a result, the peristaltic dosing pump tube cannot absorb the liquid, and the pump wheel idles and dry grinds. This phenomenon causes considerable loss to the service life of the pump and the hose. The specific impacts are as follows:

1. Transmission accuracy: Due to the high viscosity and strong adhesion of the liquid, the transmission accuracy and flow rate will be reduced.

2. Service life: The occurrence of dry grinding accelerates the loss of the peristaltic pump service life.

Notes:

1. When buying a peristaltic liquid pump, the accuracy is measured by water, and the standard unit is water. The actual accuracy will vary depending on the transmitted liquid.

2. Other equipment for transmitting liquids include injection pumps, gear pumps, etc. If the properties of the transmitted liquid are special, other suitable equipment can be selected.

3. After the pump tube has been used for about 220 hours, the hose can be turned over (i.e. rotated 90 degrees), because long-term squeezing of one side of the hose is prone to single-side damage, and turning it over can increase the service life.
