How Do Micro Peristaltic Pumps Work?

The mini peristaltic pumps are low-pressure product pumps, the general working pressure does not exceed 0.7Mpa, and the large peristaltic pump (hose pump) can reach more than 1Mpa. The miniature peristaltic pump alternately squeezes and releases the elastic delivery hose of the pump, so that the peristaltic pump draws fluid. Just like pinching and squeezing a hose with two fingers, the hose moves with the fingers, and the liquid creates a negative pressure in the hose. There are many types of fluids transmitted by micro peristaltic pumps, not only fluids with particles, but also fluids with strong acids, strong bases and strong organic solvents. You only need to choose a hose suitable for the fluid.

What Are the Advantages of Using Micro Peristaltic Pumps?

How to Maintain a Micro Peristaltic Pump?

The composition of the mini peristaltic pumps is divided into three components: the driver, the pump head, and the hose. During use, the hose is consumable and needs to be replaced regularly. The driver and pump head are maintenance-free parts, and only need to be dry and cleaned daily. Work without special maintenance.

In the use of the miniature peristaltic pump head, the common damages include the following situations, which need to be paid attention to during use: First, the speed is too high, exceeding the design speed requirements of the pump head; Second, accidental fall from high altitude, resulting in deformation or damage of the pump head; Third, the leakage of the hose causes the liquid to enter the rollers of the pump head and the main shaft bearing, and damage the bearings.
