If the pump outlet leads to two paths, will backflow occur?
Thread Content
Our on-line analyzer is connected at the inlet of the pump, taken from the outlet pipeline of the shielded pump; after passing through the analyzer, the fluid returns to the inlet of this pump. But the outlet of this pump leads to the vacuum tower, where the pressure is around -91; could the negative pressure in that tower prevent the analyzer from accepting samples? Or siphoning may occur due to reasons such as a high flow rate at the pump outlet, preventing the analyzer from accessing the sample
Unless the vacuum level is higher than the pump’s outlet pressure.
There is a negative pressure pump for use in vacuum conditions. The outlet is equipped with a check valve to prevent backflow.
