1. pressure limitation: using flexible tube will cause pressure to be restricted.

2. the pump will generate a pulse flow when it operates.

The solution is:

Increasing the number of rollers will reduce the flow rate.

(2) Pulse Suppressor: Pulse Suppressor is a simple positioning vessel. Its working principle is that the air is more compressible than the liquid, and the air bag that the pulse flows into the vessel and the liquid sinks to absorb the pulse and then flows out smoothly.

3. the traffic will decay with time. (due to wear of hose)

The pump outlet pressure has certain limitations, generally not exceeding 0.3MPa, usually between 0.1-0.2MPa.
