Flare line at the inlet and outlet of the gas pump
Thread Content
Is it appropriate to lead the flare pipeline for the inlet and outlet of the gas pump from the upper part of the pump? Is it better to lead it out from the lower part? It doesn’t feel right to introduce it at the bottom. Thank you!
Which pump? VS6 (vertical sack pump)?
There are vertical high-speed pumps and horizontal centrifugal pumps
Vent from the upper part of the pump, and drain the residual liquid from the lower part of the pump
The liquefied gas pumps in our equipment all have a flare connected to the pump outlet, that is, they are vented to a higher location for use in filling the pumps. Some pumps also have a drain valve on the inlet pipeline (after the inlet filter), which is generally used only during purging or maintenance
When repairing the pump, the residual liquid inside the pump is discharged to the flare.
To be honest, I’m not quite sure what you mean. But I can tell you that in our workshop, the venting systems are installed at the pump outlet pipelines; there is no venting system at the inlet pipeline. The pumps are equipped with dry gas seals, and the venting system for these dry gas seals is connected above the mechanical seal
