HOW PERISTALTIC PUMPS WORK

Peristaltic pumps work according to the peristaltic principle. The hose, as the central component in the pump, is compressed by sliding shoes or rollers that are attached to a rotor and moved over the hose. The pinched spot moves along the tube, and the contained liquid is pushed forward. After compression, the restoring forces of the high-strength hose ensure that it opens back into its original shape. This creates a strong negative pressure, which supplies more liquid from the line.

In high-pressure hose pumps in particular, the rotor is exposed to heavy loads.

Peristaltic pumps are a pre-training pump and work according to the peristaltic principle. The hose, which can consist of a variety of materials, is paced in the pump housing. The pump rotor exerts pressure when it rotates on a set of rollers or pressure jaws which, in turn, compress the hose. This creates a vacuum behind the roller or pressure jaw that sucks in liquid in the hose while the next roller or pressure jaw gently pushes the liquid forward through the hose.The only wear part of the pump is the hose which can be quickly and economically replaced on site.

The hose, as the central component of the pump, is compressed by pressure jaws or rollers attached to a rotor and moved over the hose. The pinched spot moves along the tube and the entrapped liquid is pushed forward. After compression, restorative forces from the high-strength hose ensure that it opens back to its original shape. This creates a strong negative pressure, which adds more fluid from the pipe.
Especially in high-pressure hose pumps, the rotor is exposed to large loads. Some peristaltic pumps have a lifetime warranty on the rotor. Peristaltic pumps with an integrated rotor bearing significantly reduce the mechanical stress on the gear unit and the motor, which ensures a longer service life.
