The safety valves of methanol-poor pumps are sometimes installed at the inlet and sometimes on the outlet pipeline; each placement has its own advantages. What is the best way to install them?

The safety valves on methanol pumps are sometimes installed at the inlet and sometimes on the outlet pipeline, each serving its own purpose. Is it more in exports or in imports? It’s best to install better protective equipment for everything.
It is better to install it on the inlet pipeline, as it can provide protection.
According to the specifications, it is installed at the inlet to protect the safety of the inlet pipes and equipment, while it is installed on the outlet pipeline to protect the safety of the pump and related pipelines. What the Lind engineer said
When the device is equipped with a methanol collection tank, it is reasonable to install it at the outlet.
It is installed at the outlet to prevent damage to the pump caused by liquid backflow in case the check valve at the pump outlet fails
Installing it on the inlet can provide more effective protection for the equipment; the inlet pressure is usually low
Installing a safety valve at the low-methanol inlet is used to prevent leakage from the check valve and backflow of high-pressure methanol
