After the fluid enters the peristaltic pumps pump head is accumulated between the two rollers, forming a”fluid pillow." Followed by a brief break, because the back section of the pump tube has been blocked roller, again forming a”fluid pillow."So the cycle, they form a pulsating, rather than smooth continuous fluid.


If you do not want this pulsation, can be used peristaltic pumps tube locking degree adjustable pump head, which can reduce the degree of pulsation by 25%, because it makes the degree of drying fluid between the pillow slowed. However, some applications of peristaltic pumps pulsation generated more restrictive. For them, a 25% reduction in the degree of pulsation is not enough.

In this case, consider the use of other four measures to further reduce the pulsation: the use of the pump head with a staggered shape and more roller locking; the use of the multi-head form with staggered pulsation; the use of pulsation buffers; and replacement discharge pipe configuration.

Timing also requires: when the roller is located in the top dead center of the pump head(TDC)just the maximum degree of locking. However, some pumps have six to eight rollers installed in their heads and are designed with a staggered lock----that is: the maximum degree of locking, the roller has been transferred from the top dead center of the pump head. The combination of these two designs can be used to eliminate pulsation.
